Non-coding plasmid DNA induces IFN-gamma in vivo and suppresses autoimmune encephalomyelitis. (1/278)
Regulatory sequences used in plasmids for naked DNA vaccination can modulate cytokine production in vivo. We demonstrate here that injection of plasmid DNA can suppress the prototypic T cell-mediated autoimmune disease, experimental autoimmune encephalomyelitis, by inducing IFN-gamma. (+info)Non-purulent meningoencephalomyelitis of a Pacific striped dolphin (Lagenorhynchus obliquidens). The first evidence of morbillivirus infection in a dolphin at the Pacific Ocean around Japan. (2/278)
On March 22, 1998, a mature, male, hyposthenic Pacific striped dolphin (Lagenorhynchus obliquidens) was stranded at Aoshima Beach in Miyazaki prefecture, Japan. A necropsy performed 14 hr after death revealed mild diffuse congestion and edema of the leptomeninges and mild pulmonary atelectasis. Histopathologically, non-purulent inflammatory were observed throughout the cerebrum, thalamus, midbrain, pons, medulla oblongata, and spinal cord. Hematoxylin and eosin stain revealed no viral inclusion bodies. Immunohistochemistry using a monoclonal antibody against nucleoprotein of canine distemper virus (CDV-NP) revealed a number of CDV-NP-positive granular deposits in the cytoplasm and cell processes of the degenerating or intact neurons. The present paper is a first report of spontaneously occurred morbillivirus infection in a dolphin at the Pacific Ocean around Japan. (+info)Immunity to heat shock proteins and neurological disorders of women. (3/278)
Stress or heat shock proteins are constitutively expressed in normal CNS tissues in a variety of cell types (oligodendrocytes, astrocytes, and neurons). Their presence may protect cells from various stresses, such as hypoxia, anoxia, and excessive excitatory stimulation. Increased amounts of hsp are expressed in various cells of the CNS during acute toxic-metabolic states and in chronic degenerative and inflammatory diseases. Increased expression of hsp may lead to immune responses to these proteins. Antibodies to mycobacterial hsp bind to normal human myelin and to oligodendrocytes in regions of MS demyelination. Cellular immune responses to hsp occur with increased frequency and magnitude in persons with MS, especially those with recent onset of disease. In addition, there are populations of T cells expressing gamma/delta T cells in the brains and spinal fluids of persons with MS, suggesting an in situ immune response to hsps. Humoral immune responses to hsp are found in CSF, but no disease specificity has been documented. Some myelin proteins have sequence homology with particular hsps. One instance is the homology between a peptide of mycobacterial Hsp65 and the myelin protein CNP. Our data on EAE suggest that immune responses to either cross-reactive hsp epitopes or whole hsp can modify the course of both acute and chronic relapsing EAE. In addition, the severity and frequency of environmental exposure to infectious agents can modify the course of EAE, possibly by altering the patterns of immune response to hsp. Finally, tolerance to the small hsp, alpha B-crystallin, a putative autoantigen in persons with MS, alters the course of relapsing EAE, supporting its role in chronic, autoimmune CNS disease. Modifying immune responses to hsp may be a potential new treatment option for persons with MS. (+info)Antibody prevents virus reactivation within the central nervous system. (4/278)
The neurotropic JHM strain of mouse hepatitis virus (JHMV) produces an acute CNS infection characterized by encephalomyelitis and demyelination. The immune response cannot completely eliminate virus, resulting in persistence associated with chronic ongoing CNS demyelination. The contribution of humoral immunity to viral clearance and persistent infection was investigated in mice homozygous for disruption of the Ig mu gene (IgM-/-). Acute disease developed with equal kinetics and severity in IgM-/- and syngeneic C57BL/6 (wt) mice. However, clinical disease progressed in IgM-/- mice, while wt mice recovered. Viral clearance during acute infection was similar in both groups, supporting a primary role of cell-mediated immunity in viral clearance. In contrast to wt mice, in which infectious virus was reduced to below detection following acute infection, increasing infectious virus was recovered from the CNS of the IgM-/- mice following initial clearance. No evidence was obtained for selection of variant viruses nor was there an apparent loss of cell-mediated immunity in the absence of Ab. Passive transfer of anti-JHMV Ab following initial clearance prevented reactivation of infectious virus within the CNS of IgM-/- mice. These data demonstrate the clearance of infectious virus during acute disease by cell-mediated immunity. However, immunologic control is not maintained in the absence of anti-viral Ab, resulting in recrudescence of infectious virus. These data suggest that humoral immunity plays no role in controlling virus during acute infection, but plays an important role in establishing and maintaining CNS viral persistence. (+info)Pigs with highly prevalent antibodies to human coronavirus and swine haemagglutinating encephalomyelitis virus in the Tohoku District of Japan. (5/278)
From 1985 to 1988, a total of 2496 swine sera from 60 farms in the Tohoku District of the Honshu Island of Japan were examined for antibodies to swine haemagglutinating encephalomyelitis virus (HEV), human coronavirus (HCV) and bovine coronavirus (BCV) by haemagglutination-inhibition (HI) test. Antibodies to HEV 67N strain and HCV OC43 strain were highly prevalent with positivity rates of 82.1 and 91.4%, respectively, while seropositivity rate to BCV Kakegawa strain was 44.2%. No clinical signs of HEV infection were noticed in any farms including farms with relatively high seropositivity. The results suggested that HCV or antigenitically related virus(es) as well as HEV might be perpetuated in swine in the Tohoku District. (+info)The clinical and epidemiological profile of tick-borne encephalitis in southern Germany 1994-98: a prospective study of 656 patients. (6/278)
Seven hundred and nine patients fell ill in southern Germany (Baden-Wurttemberg) after infection with the tick-borne encephalitis (TBE) virus between 1994 and 1998. Detailed clinical and epidemiological data on TBE were available for 656 patients. A biphasic course of the disease occurred in 485 patients (74%). TBE presented as meningitis in 320 patients (49%), as meningoencephalitis in 270 (41%) and as meningoencephalomyelitis in 66 (10%). Eight of the patients (1.2%) died from TBE. Four hundred and forty-five patients (68%) had noticed a tick bite and the first symptoms occurred, on average, 7 days later. The most frequent neurological symptoms were impairment of consciousness (31%), ataxia (18%) and paresis of the extremities (15%) and cranial nerves (11%). Laboratory investigations revealed leucocytosis in the peripheral blood in 224 out of 392 patients (74%), elevation of the erythrocyte sedimentation rate in 223 out of 245 (91%), increased C-reactive protein in 127 out of 155 (82%), pleocytosis in the CSF of all patients tested, damage of the blood-CSF barrier in 255 out of 322 (79%), abnormalities in EEG in 165 out of 214 (77%) and abnormalities in MRI in 18 out of 102 (18%). In general, adolescents up to 14 years of age had a more favourable course of the disease than adults. Of 230 patients who were re-examined at a later time, 53 (23%) had moderate or severe sequelae. Patients with sequelae presented more frequently (P < 0.001) with impaired consciousness (Glasgow Coma Scale < 7), ataxia, pareses of the extremities or cranial nerves, a need for assisted ventilation, abnormal findings in MRI, pleocytosis > 300 cells/microl and impairment of the blood-CSF barrier (total protein > 600 mg/l). In view of the severity of the illness and the high frequency of sequelae, active immunization against TBE is recommended for all subjects living in and travelling to areas of risk. Prevention of TBE by post-exposure prophylaxis with hyperimmunoglobulins is less effective and therefore should be performed only when absolutely necessary. (+info)MR imaging findings of enteroviral encephaloymelitis: an outbreak in Taiwan. (7/278)
BACKGROUND AND PURPOSE: An outbreak of enterovirus infection occurred in Taiwan from late spring to early fall of 1998. Most of the pediatric infections presented as hand-foot-mouth disease (HFMD) and herpangina. A small portion of patients had symptoms of polio-like encephalitis and paralysis. The purpose of this study was to review the MR imaging findings in CNS involvement of enterovirus infection. METHODS: Twenty patients who had HFMD and clinical encephalitis were examined with MR imaging. T1-weighted and T2-weighted MR images were obtained. From the rectum, throat, CSF, and peripheral blood, the presence of enterovirus 71 (EV 71) was determined by virus culture, immunofluorescent microscopy, immunologic dot blotting, and reverse-transcription polymerase chain reaction. RESULTS: MR imaging studies of 20 patients showed hyperintensity in the brain stem and spinal cord in 15 patients, as seen on T2-weighted images. The major CNS lesions were in the medulla oblongata, pons, midbrain, and the dentate nuclei of the cerebellum. In some cases, the lesions involved the spinal cord (three cases) as well as the thalamus (two cases) and putamina (one case). Five patients had normal MR imaging results. After the appropriate management for tachycardia and tachypnea, 18 patients recovered within 1 to 2 weeks. In the follow-up MR imaging examination of five patients, the lesions completely disappeared within 2 weeks to 2 months. In two patients who were still respirator-dependent, MR imaging showed the tissue destruction in the posterior portions of the medulla, pons, and the ventral horns of cervical spinal cord. In one patient, most of midbrain was damaged. The presence of EV 71 was detected in specimens from 18 patients. CONCLUSION: Because EV 71 was identified in 18 patients, and no other virus was detected, EV 71 was determined to be the major causative agent of this encephalomyelitis. Brain stem and cervical spinal cord involvement are characteristic findings of enteroviral encephalomyelitis. (+info)A central role for CD4(+) T cells and RANTES in virus-induced central nervous system inflammation and demyelination. (8/278)
Infection of C57BL/6 mice with mouse hepatitis virus (MHV) results in a demyelinating encephalomyelitis characterized by mononuclear cell infiltration and white matter destruction similar to the pathology of the human demyelinating disease multiple sclerosis. The contributions of CD4(+) and CD8(+) T cells in the pathogenesis of the disease were investigated. Significantly less severe inflammation and demyelination were observed in CD4(-/-) mice than in CD8(-/-) and C57BL/6 mice (P < or = 0.002 and P < or = 0.001, respectively). Immunophenotyping of central nervous system (CNS) infiltrates revealed that CD4(-/-) mice had a significant reduction in numbers of activated macrophages/microglial cells in the brain compared to the numbers in CD8(-/-) and C57BL/6 mice, indicating a role for these cells in myelin destruction. Furthermore, CD4(-/-) mice displayed lower levels of RANTES (a C-C chemokine) mRNA transcripts and protein, suggesting a role for this molecule in the pathogenesis of MHV-induced neurologic disease. Administration of RANTES antisera to MHV-infected C57BL/6 mice resulted in a significant reduction in macrophage infiltration and demyelination (P < or = 0.001) compared to those in control mice. These data indicate that CD4(+) T cells have a pivotal role in accelerating CNS inflammation and demyelination within infected mice, possibly by regulating RANTES expression, which in turn coordinates the trafficking of macrophages into the CNS, leading to myelin destruction. (+info)Encephalomyelitis, Autoimmune, Experimental (EAE) is an animal model of multiple sclerosis (MS), a chronic inflammatory autoimmune disorder that affects the central nervous system (CNS). EAE is induced by the administration of myelin antigens, such as myelin basic protein (MBP), to susceptible animals, which triggers an autoimmune response against the myelin sheath that surrounds nerve fibers in the CNS. In EAE, the immune system mistakenly attacks the myelin sheath, leading to inflammation, demyelination, and axonal damage. This results in a range of neurological symptoms, including paralysis, loss of coordination, and cognitive impairment, which are similar to those seen in MS patients. EAE is widely used in research to study the pathogenesis of MS and to test potential treatments for the disease. It is a valuable tool for understanding the complex interplay between the immune system, the nervous system, and the environment that contributes to the development of MS.
Encephalomyelitis is a medical condition that refers to the inflammation of both the brain and spinal cord. It can be caused by a variety of factors, including viral or bacterial infections, autoimmune disorders, or exposure to toxins. The symptoms of encephalomyelitis can vary widely depending on the location and severity of the inflammation. Common symptoms may include fever, headache, nausea, vomiting, confusion, seizures, muscle weakness, and difficulty with coordination and balance. In severe cases, encephalomyelitis can lead to permanent neurological damage or even death. Treatment for encephalomyelitis typically involves managing symptoms and addressing the underlying cause of the inflammation. This may include antiviral or antibiotic medications, corticosteroids to reduce inflammation, and supportive care such as hydration and nutrition. In some cases, physical therapy or other forms of rehabilitation may be necessary to help patients recover from the effects of the condition.
Acute disseminated encephalomyelitis (ADEM) is a rare autoimmune disorder that affects the central nervous system (CNS). It is characterized by inflammation and damage to the myelin sheath, which is the protective covering of nerve fibers in the brain and spinal cord. In ADEM, the immune system mistakenly attacks the myelin sheath, causing it to break down and release inflammatory chemicals. This leads to inflammation and damage to the nerve fibers, which can result in a wide range of symptoms, including fever, headache, fatigue, and difficulty with coordination and balance. The symptoms of ADEM can vary widely depending on the location and severity of the inflammation in the brain and spinal cord. Some people may experience only mild symptoms, while others may have more severe symptoms that can be life-threatening. ADEM is usually a self-limiting condition, meaning that it will resolve on its own over time. However, in some cases, treatment with corticosteroids or other immunosuppressive drugs may be necessary to reduce inflammation and prevent further damage to the nervous system.
Myelin-Oligodendrocyte Glycoprotein (MOG) is a protein that is expressed on the surface of oligodendrocytes, which are a type of glial cell that produce myelin in the central nervous system (CNS). Myelin is a fatty substance that surrounds and insulates nerve fibers, allowing them to transmit electrical signals more efficiently. MOG is a type of autoantigen, which means that it can trigger an immune response in the body. In some cases, this immune response can lead to the destruction of myelin and the formation of lesions in the CNS, a condition known as multiple sclerosis (MS). MOG-related disorders are a group of conditions that are characterized by the production of antibodies against MOG and the development of inflammation and demyelination in the CNS. MOG-related disorders can present with a range of symptoms, including weakness, numbness, tingling, and vision problems. Some people may also experience cognitive and emotional changes, as well as fatigue and difficulty walking. Treatment for MOG-related disorders typically involves the use of immunosuppressive medications to reduce inflammation and prevent further damage to the CNS.
Encephalomyelitis, equine refers to an inflammation of the brain and spinal cord in horses. It is a serious and potentially life-threatening condition that can be caused by a variety of factors, including viral infections, bacterial infections, and autoimmune diseases. Symptoms of equine encephalomyelitis may include fever, lethargy, loss of appetite, muscle weakness, difficulty walking, and changes in behavior or coordination. In severe cases, the horse may experience seizures, paralysis, or even coma. Diagnosis of equine encephalomyelitis typically involves a combination of clinical examination, laboratory tests, and imaging studies such as MRI or CT scans. Treatment may involve supportive care to manage symptoms and prevent complications, as well as specific therapies to address the underlying cause of the inflammation. Prevention of equine encephalomyelitis is important, and may involve vaccination against certain viruses and bacteria that can cause the condition, as well as careful management of the horse's environment and diet to reduce the risk of infection.
Myelin Basic Protein (MBP) is a protein that is found in the myelin sheath, which is a fatty layer that surrounds and insulates nerve fibers in the central nervous system (CNS). MBP plays a crucial role in the formation and maintenance of the myelin sheath, and it is thought to be involved in the development and progression of several neurological disorders, including multiple sclerosis (MS), neuromyelitis optica (NMO), and some forms of leukodystrophy. In these conditions, the immune system mistakenly attacks the myelin sheath, leading to inflammation and damage to the nerve fibers. MBP is also being studied as a potential biomarker for these disorders, as levels of MBP in the blood or cerebrospinal fluid may be elevated in people with these conditions.
Myelin-Associated Glycoprotein (MAG) is a protein that is found in the myelin sheath, which is a layer of fatty substance that surrounds and insulates nerve fibers in the central and peripheral nervous systems. MAG plays a role in the development and maintenance of myelin, and it is also involved in the regulation of nerve cell signaling. In the medical field, MAG has been studied as a potential target for the treatment of various neurological disorders, including multiple sclerosis, Guillain-Barré syndrome, and peripheral neuropathy.
Myelin proteins are a group of proteins that are essential for the formation and maintenance of myelin, a fatty substance that surrounds and insulates nerve fibers in the central and peripheral nervous systems. Myelin is critical for the proper functioning of the nervous system, as it allows electrical signals to travel quickly and efficiently along nerve fibers. There are several different types of myelin proteins, including proteolipid protein (PLP), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG). These proteins are synthesized by specialized cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Mutations in genes that encode myelin proteins can lead to a variety of neurological disorders, including multiple sclerosis, leukodystrophies, and Charcot-Marie-Tooth disease. Understanding the structure and function of myelin proteins is therefore important for developing new treatments for these conditions.
Myelin Proteolipid Protein (PLP) is a major protein component of the myelin sheath, which is a fatty layer that surrounds and insulates nerve fibers in the central nervous system (CNS). PLP is synthesized in oligodendrocytes, which are specialized cells that produce myelin in the CNS. PLP plays a critical role in the formation and maintenance of myelin sheaths. It is thought to help stabilize the myelin membrane and regulate the flow of ions across the membrane. PLP is also involved in the process of myelin repair and regeneration following injury to the CNS. Abnormalities in PLP synthesis or function have been linked to several neurological disorders, including multiple sclerosis (MS), a chronic inflammatory disease that affects the myelin sheaths of nerve fibers in the CNS. Mutations in the PLP gene have also been associated with Pelizaeus-Merzbacher disease (PMD), a rare inherited disorder that affects the development and maintenance of myelin in the CNS.
Multiple Sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system (CNS), which includes the brain, spinal cord, and optic nerves. In MS, the immune system attacks and damages the protective covering (myelin) that surrounds nerve fibers in the CNS, leading to inflammation, scarring (sclerosis), and loss of nerve function. The symptoms of MS can vary widely and may include: - Fatigue - Muscle weakness - Numbness or tingling in the limbs - Blurred vision - Difficulty with coordination and balance - Difficulty speaking or understanding speech - Seizures - Depression and anxiety MS can be diagnosed through a combination of physical exams, medical history, and imaging tests such as magnetic resonance imaging (MRI). There is currently no cure for MS, but treatments are available to manage symptoms and slow the progression of the disease.
Demyelinating diseases are a group of neurological disorders characterized by the loss of the protective myelin sheath that surrounds nerve fibers in the central nervous system (CNS). The myelin sheath is essential for the proper functioning of the nervous system, as it allows electrical signals to travel quickly and efficiently along the nerve fibers. Demyelinating diseases can be classified into two main categories: primary and secondary. Primary demyelinating diseases, also known as idiopathic demyelinating diseases, are caused by an autoimmune response in which the body's immune system mistakenly attacks and destroys the myelin sheath. Examples of primary demyelinating diseases include multiple sclerosis (MS), acute disseminated encephalomyelitis (ADEM), and neuromyelitis optica (NMO). Secondary demyelinating diseases, on the other hand, are caused by an underlying condition that damages the myelin sheath. Examples of secondary demyelinating diseases include chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), Guillain-Barré syndrome (GBS), and transverse myelitis. Symptoms of demyelinating diseases can vary widely depending on the specific disease and the location of the affected nerve fibers. Common symptoms include weakness, numbness, tingling, difficulty with coordination and balance, vision problems, and cognitive impairment. Treatment for demyelinating diseases typically involves medications to reduce inflammation and slow the progression of the disease, as well as physical therapy and other supportive measures to manage symptoms and improve quality of life.
Cardiovirus infections are a group of viral infections that primarily affect the heart and circulatory system. These viruses are members of the Picornaviridae family and include coxsackieviruses and echoviruses. Coxsackieviruses are the most common cause of cardiovirus infections and can cause a range of symptoms, including fever, headache, muscle aches, and respiratory symptoms. In some cases, coxsackievirus infections can lead to more serious complications, such as myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining around the heart). Echoviruses are another type of cardiovirus that can cause a range of symptoms, including fever, headache, and muscle aches. In some cases, echovirus infections can also lead to more serious complications, such as meningitis (inflammation of the membranes surrounding the brain and spinal cord) and encephalitis (inflammation of the brain). Cardiovirus infections are typically spread through contact with infected individuals or contaminated surfaces, and can be prevented through good hygiene practices such as washing hands frequently and avoiding close contact with sick individuals. Treatment for cardiovirus infections typically involves supportive care to manage symptoms and prevent complications. In severe cases, hospitalization may be necessary.
Encephalomyelitis, Eastern Equine is a viral infection that primarily affects horses, but can also infect other equids such as mules and donkeys. The virus is transmitted through the bite of an infected mosquito, and the symptoms of the disease can range from mild to severe. The disease is characterized by inflammation of the brain and spinal cord, which can lead to a range of neurological symptoms such as fever, loss of appetite, weakness, and difficulty walking. In severe cases, the disease can lead to paralysis, seizures, and even death. There is no specific treatment for Eastern Equine Encephalomyelitis, and the focus of management is on providing supportive care to help the horse recover. Prevention is the best approach, and this includes controlling mosquito populations through the use of insecticides and other measures, as well as vaccination of horses at risk.
In the medical field, a peptide fragment refers to a short chain of amino acids that are derived from a larger peptide or protein molecule. Peptide fragments can be generated through various techniques, such as enzymatic digestion or chemical cleavage, and are often used in diagnostic and therapeutic applications. Peptide fragments can be used as biomarkers for various diseases, as they may be present in the body at elevated levels in response to specific conditions. For example, certain peptide fragments have been identified as potential biomarkers for cancer, neurodegenerative diseases, and cardiovascular disease. In addition, peptide fragments can be used as therapeutic agents themselves. For example, some peptide fragments have been shown to have anti-inflammatory or anti-cancer properties, and are being investigated as potential treatments for various diseases. Overall, peptide fragments play an important role in the medical field, both as diagnostic tools and as potential therapeutic agents.
Interleukin-17 (IL-17) is a cytokine, a type of signaling molecule, that plays a role in the immune system's response to infection and inflammation. It is produced by certain types of immune cells, including T cells and natural killer T cells, and is involved in the recruitment and activation of other immune cells, such as neutrophils and macrophages, to the site of infection or injury. IL-17 is also involved in the development of autoimmune diseases, such as rheumatoid arthritis and psoriasis, where it contributes to inflammation and tissue damage. In addition, IL-17 has been implicated in the pathogenesis of inflammatory bowel disease, multiple sclerosis, and other inflammatory conditions. In the medical field, IL-17 is a target for the development of new therapies for autoimmune diseases and other inflammatory conditions. Inhibitors of IL-17, such as biologic drugs, have been shown to be effective in reducing inflammation and improving symptoms in patients with these conditions.
Demyelinating autoimmune diseases of the central nervous system (CNS) are a group of disorders characterized by the loss of the protective myelin sheath that surrounds nerve fibers in the brain and spinal cord. This loss of myelin can lead to damage or dysfunction of the nerve fibers, resulting in a range of symptoms depending on the specific location and extent of the demyelination. The most well-known demyelinating autoimmune disease of the CNS is multiple sclerosis (MS), which is an inflammatory disorder that affects the myelin and the nerve fibers in the brain and spinal cord. Other demyelinating autoimmune diseases of the CNS include acute disseminated encephalomyelitis (ADEM), neuromyelitis optica (NMO), and optic neuritis. These diseases are considered autoimmune because they are caused by an abnormal immune response in which the body's immune system attacks its own tissues. In the case of demyelinating autoimmune diseases of the CNS, the immune system mistakenly attacks the myelin sheath, leading to inflammation and damage to the nerve fibers. Treatment for demyelinating autoimmune diseases of the CNS typically involves the use of immunosuppressive medications to reduce inflammation and slow the progression of the disease. In some cases, physical therapy and other supportive therapies may also be used to manage symptoms and improve quality of life.
Encephalomyelitis, Enzootic Porcine is a viral infection that affects pigs and is caused by the Porcine rubulavirus. The virus primarily affects the central nervous system of pigs, leading to inflammation of the brain and spinal cord. The disease is commonly known as "porcine rubulavirus encephalomyelitis" or "PRV encephalomyelitis." The symptoms of encephalomyelitis, enzootic porcine include fever, lethargy, loss of appetite, and neurological signs such as weakness, tremors, and seizures. In severe cases, the disease can lead to paralysis and death. Encephalomyelitis, enzootic porcine is primarily spread through contact with infected pigs or contaminated materials. The virus can also be transmitted through the air, as the virus is shed in the respiratory secretions of infected pigs. There is no specific treatment for encephalomyelitis, enzootic porcine, and the disease is usually fatal. Prevention measures include vaccination of pigs, proper hygiene and sanitation practices on pig farms, and the isolation of infected pigs.
Enterovirus infections are a group of viral infections caused by enteroviruses, which are a type of RNA virus that primarily affect the gastrointestinal tract and nervous system. These viruses are highly contagious and can be transmitted through contact with contaminated surfaces, bodily fluids, or respiratory droplets. Enterovirus infections can cause a range of symptoms, depending on the specific virus and the severity of the infection. Common symptoms include fever, headache, nausea, vomiting, diarrhea, and rash. In some cases, enterovirus infections can lead to more serious complications, such as meningitis, encephalitis, and paralysis. There is no specific treatment for enterovirus infections, as the viruses cannot be killed by antibiotics. Treatment typically involves managing symptoms and providing supportive care, such as fluids and pain relief. In severe cases, hospitalization may be necessary. Prevention of enterovirus infections involves practicing good hygiene, such as washing hands frequently and avoiding contact with infected individuals or surfaces. Vaccines are not currently available for all types of enteroviruses, but some vaccines are in development.
Chronic Fatigue Syndrome (CFS) is a medical condition characterized by persistent and unexplained fatigue that is not relieved by rest and is accompanied by a range of other symptoms that can include muscle pain, joint pain, headaches, memory problems, and difficulty concentrating. The exact cause of CFS is not fully understood, but it is believed to be related to an abnormal immune response or an issue with the body's energy metabolism. CFS can be a debilitating condition that affects a person's ability to work, attend school, and perform daily activities. Treatment for CFS typically involves a combination of medications, lifestyle changes, and therapy to manage symptoms and improve quality of life.
Cytokines are small proteins that are produced by various cells of the immune system, including white blood cells, macrophages, and dendritic cells. They play a crucial role in regulating immune responses and inflammation, and are involved in a wide range of physiological processes, including cell growth, differentiation, and apoptosis. Cytokines can be classified into different groups based on their function, including pro-inflammatory cytokines, anti-inflammatory cytokines, and regulatory cytokines. Pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1), promote inflammation and recruit immune cells to the site of infection or injury. Anti-inflammatory cytokines, such as interleukin-10 (IL-10) and transforming growth factor-beta (TGF-beta), help to dampen the immune response and prevent excessive inflammation. Regulatory cytokines, such as interleukin-4 (IL-4) and interleukin-13 (IL-13), help to regulate the balance between pro-inflammatory and anti-inflammatory responses. Cytokines play a critical role in many diseases, including autoimmune disorders, cancer, and infectious diseases. They are also important in the development of vaccines and immunotherapies.
In the medical field, "Disease Models, Animal" refers to the use of animals to study and understand human diseases. These models are created by introducing a disease or condition into an animal, either naturally or through experimental manipulation, in order to study its progression, symptoms, and potential treatments. Animal models are used in medical research because they allow scientists to study diseases in a controlled environment and to test potential treatments before they are tested in humans. They can also provide insights into the underlying mechanisms of a disease and help to identify new therapeutic targets. There are many different types of animal models used in medical research, including mice, rats, rabbits, dogs, and monkeys. Each type of animal has its own advantages and disadvantages, and the choice of model depends on the specific disease being studied and the research question being addressed.
Encephalomyelitis, Western Equine, also known as equine encephalomyelitis, is a viral disease that affects horses and other equids. It is caused by the West Nile virus, which is transmitted to horses through the bite of infected mosquitoes. The symptoms of equine encephalomyelitis can vary depending on the severity of the infection. In some cases, horses may show no signs of illness at all. However, in more severe cases, horses may develop fever, loss of appetite, muscle weakness, and difficulty moving. In some cases, the disease can also affect the brain and spinal cord, leading to neurological symptoms such as seizures, paralysis, and loss of coordination. There is no specific treatment for equine encephalomyelitis, and the prognosis for horses that develop severe symptoms is generally poor. Prevention is the best way to protect horses from the disease, and this can be achieved through measures such as mosquito control and vaccination.

Freund's Adjuvant is named after its discoverer, Paul Ehrlich's student, Paul Freund.
Glycoproteins are a type of protein that contains one or more carbohydrate chains covalently attached to the protein molecule. These carbohydrate chains are made up of sugars and are often referred to as glycans. Glycoproteins play important roles in many biological processes, including cell signaling, cell adhesion, and immune response. They are found in many different types of cells and tissues throughout the body, and are often used as markers for various diseases and conditions. In the medical field, glycoproteins are often studied as potential targets for the development of new drugs and therapies.
Autoimmune diseases are a group of disorders in which the immune system mistakenly attacks healthy cells and tissues in the body. In a healthy immune system, the body recognizes and attacks foreign substances, such as viruses and bacteria, to protect itself. However, in autoimmune diseases, the immune system becomes overactive and begins to attack the body's own cells and tissues. There are over 80 different types of autoimmune diseases, and they can affect various parts of the body, including the joints, skin, muscles, blood vessels, and organs such as the thyroid gland, pancreas, and liver. Some common examples of autoimmune diseases include rheumatoid arthritis, lupus, multiple sclerosis, type 1 diabetes, and inflammatory bowel disease. The exact cause of autoimmune diseases is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Treatment for autoimmune diseases typically involves managing symptoms and reducing inflammation, and may include medications, lifestyle changes, and in some cases, surgery.
Encephalomyelitis, Venezuelan Equine (VEE) is a viral infection that primarily affects horses, but can also infect humans and other animals. It is caused by the Venezuelan equine encephalitis virus (VEEV), which is transmitted to horses through the bite of infected mosquitoes. VEE can cause a range of clinical signs in horses, including fever, lethargy, loss of appetite, and muscle weakness. In severe cases, the virus can cause inflammation of the brain and spinal cord (encephalomyelitis), leading to neurological symptoms such as seizures, paralysis, and even death. In humans, VEE can cause a similar range of symptoms, but is generally less severe. The symptoms of VEE in humans can include fever, headache, muscle pain, and nausea. In some cases, VEE can cause more serious neurological symptoms, such as encephalitis or meningitis. VEE is considered a serious public health concern in areas where it is prevalent, as it can be transmitted to humans through the bite of infected mosquitoes. Prevention measures include vaccination of horses and other animals, as well as the use of insect repellents and other measures to reduce mosquito populations.

Vaccines have been developed to prevent COVID-19, and antiviral medications are being studied for their potential to treat the disease.
Interleukin-10 (IL-10) is a cytokine, which is a type of signaling molecule that plays a role in regulating the immune system. It is produced by various immune cells, including macrophages, dendritic cells, and T cells, in response to infection or inflammation. IL-10 has anti-inflammatory properties and helps to suppress the immune response, which can be beneficial in preventing excessive inflammation and tissue damage. It also has immunosuppressive effects, which can help to prevent autoimmune diseases and transplant rejection. In the medical field, IL-10 is being studied for its potential therapeutic applications in a variety of conditions, including inflammatory diseases, autoimmune diseases, and cancer. For example, IL-10 has been shown to be effective in reducing inflammation and improving symptoms in patients with rheumatoid arthritis, Crohn's disease, and other inflammatory conditions. It is also being investigated as a potential treatment for cancer, as it may help to suppress the immune response that allows cancer cells to evade detection and destruction by the immune system.
Inflammation is a complex biological response of the body to harmful stimuli, such as pathogens, damaged cells, or irritants. It is a protective mechanism that helps to eliminate the cause of injury, remove damaged tissue, and initiate the healing process. Inflammation involves the activation of immune cells, such as white blood cells, and the release of chemical mediators, such as cytokines and prostaglandins. This leads to the characteristic signs and symptoms of inflammation, including redness, heat, swelling, pain, and loss of function. Inflammation can be acute or chronic. Acute inflammation is a short-term response that lasts for a few days to a few weeks and is usually beneficial. Chronic inflammation, on the other hand, is a prolonged response that lasts for months or years and can be harmful if it persists. Chronic inflammation is associated with many diseases, including cancer, cardiovascular disease, and autoimmune disorders.
Poliomyelitis, also known as polio, is a highly infectious viral disease that primarily affects children under the age of 5. The virus is transmitted through contaminated food and water or through contact with an infected person's feces. The symptoms of polio can vary widely, but they often include fever, fatigue, headache, and muscle pain. In some cases, the virus can cause inflammation of the spinal cord or brainstem, leading to paralysis or even death. There are three types of poliovirus: poliovirus 1, poliovirus 2, and poliovirus 3. Poliovirus 1 is the most common and is responsible for the majority of polio cases worldwide. The best way to prevent polio is through vaccination. The inactivated poliovirus vaccine (IPV) and the oral poliovirus vaccine (OPV) are both effective in preventing the disease. It is important to continue to vaccinate children and adults to prevent the spread of polio and to protect vulnerable populations, such as those with weakened immune systems.
Muscle rigidity is a condition in which the muscles become stiff and difficult to move. It can be caused by a variety of factors, including neurological disorders, metabolic disorders, and certain medications. In some cases, muscle rigidity can be a symptom of a more serious underlying condition, such as Parkinson's disease or multiple sclerosis. Treatment for muscle rigidity depends on the underlying cause and may include medications, physical therapy, or other interventions.
Pleurodynia, also known as "stomach flu" or "thoracic myalgia," is a viral infection that primarily affects the muscles of the chest wall. It is caused by the Coxsackievirus B, which is a common virus that can be transmitted through contact with infected surfaces or through the air. Epidemic pleurodynia is a type of pleurodynia that occurs when the virus spreads rapidly through a population, often in a community or school setting. It is characterized by sudden onset of severe chest pain, which can be described as aching, burning, or stabbing. The pain is usually worse when the person breathes deeply or coughs, and it may be accompanied by other symptoms such as fever, headache, and muscle aches. Epidemic pleurodynia is usually self-limiting, meaning that it will resolve on its own within a few days to a week. Treatment is typically focused on relieving symptoms, such as pain and fever, and on preventing the spread of the virus to others. This may include rest, over-the-counter pain medication, and staying home from school or work until the symptoms have resolved. In severe cases, hospitalization may be necessary.
Disease susceptibility refers to an individual's increased risk of developing a particular disease or condition due to genetic, environmental, or lifestyle factors. Susceptibility to a disease is not the same as having the disease itself, but rather an increased likelihood of developing it compared to someone who is not susceptible. Genetic factors play a significant role in disease susceptibility. Certain genetic mutations or variations can increase an individual's risk of developing certain diseases, such as breast cancer, diabetes, or heart disease. Environmental factors, such as exposure to toxins or pollutants, can also increase an individual's susceptibility to certain diseases. Lifestyle factors, such as diet, exercise, and smoking, can also impact disease susceptibility. For example, a diet high in saturated fats and sugar can increase an individual's risk of developing heart disease, while regular exercise can reduce the risk. Understanding an individual's disease susceptibility can help healthcare providers develop personalized prevention and treatment plans to reduce the risk of developing certain diseases or to manage existing conditions more effectively.
Receptors, Antigen, T-Cell, alpha-beta are a type of immune cell receptor found on the surface of T-cells in the human body. These receptors are responsible for recognizing and binding to specific antigens, which are foreign substances that trigger an immune response. The alpha-beta receptors are a type of T-cell receptor that recognizes antigens presented by major histocompatibility complex (MHC) molecules on the surface of infected or cancerous cells. When the alpha-beta receptors bind to the antigen-MHC complex, it triggers a series of events that lead to the activation and proliferation of the T-cell, which then mounts an immune response against the infected or cancerous cells.
Receptors, Antigen, T-Cell are a type of immune cell receptors found on the surface of T cells in the immune system. These receptors are responsible for recognizing and binding to specific antigens, which are foreign substances or molecules that trigger an immune response. T-cell receptors (TCRs) are a type of antigen receptor that recognizes and binds to specific antigens presented on the surface of infected or abnormal cells by major histocompatibility complex (MHC) molecules. TCRs are highly specific and can recognize a wide variety of antigens, including viruses, bacteria, and cancer cells. Once a TCR recognizes an antigen, it sends a signal to the T cell to become activated and initiate an immune response. Activated T cells can then divide and differentiate into different types of effector cells, such as cytotoxic T cells that can directly kill infected or abnormal cells, or helper T cells that can stimulate other immune cells to mount a more robust response. Overall, T-cell receptors play a critical role in the immune system's ability to recognize and respond to foreign antigens, and are an important target for the development of vaccines and immunotherapies.

Glial Fibrillary Acidic Protein (GFAP) is a protein that is primarily found in astrocytes, which are a type of glial cell in the central nervous system. GFAP is a structural protein that helps to maintain the shape and stability of astrocytes, and it is also involved in various cellular processes such as cell signaling and communication. In the medical field, GFAP is often used as a diagnostic marker for certain neurological conditions, particularly those that involve damage or dysfunction of astrocytes. For example, increased levels of GFAP in the cerebrospinal fluid or brain tissue have been associated with a variety of neurological disorders, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and traumatic brain injury. Additionally, GFAP has been studied as a potential therapeutic target for these and other neurological conditions, as it plays a key role in astrocyte function and may be involved in the development and progression of disease.
In the medical field, an acute disease is a condition that develops suddenly and progresses rapidly over a short period of time. Acute diseases are typically characterized by severe symptoms and a high degree of morbidity and mortality. Examples of acute diseases include pneumonia, meningitis, sepsis, and heart attacks. These diseases require prompt medical attention and treatment to prevent complications and improve outcomes. In contrast, chronic diseases are long-term conditions that develop gradually over time and may persist for years or even decades.
Disease progression refers to the worsening or progression of a disease over time. It is a natural course of events that occurs in many chronic illnesses, such as cancer, heart disease, and diabetes. Disease progression can be measured in various ways, such as changes in symptoms, physical examination findings, laboratory test results, or imaging studies. In some cases, disease progression can be slowed or stopped through medical treatment, such as medications, surgery, or radiation therapy. However, in other cases, disease progression may be inevitable, and the focus of treatment may shift from trying to cure the disease to managing symptoms and improving quality of life. Understanding disease progression is important for healthcare providers to develop effective treatment plans and to communicate with patients about their condition and prognosis. It can also help patients and their families make informed decisions about their care and treatment options.
Hu Paraneoplastic Encephalomyelitis Antigens (Hu-PARAs) are a group of autoantibodies that are produced by the immune system in response to certain types of cancer. These antibodies can cross-react with neural tissue, leading to the development of a type of autoimmune disorder called paraneoplastic neurological syndrome (PNS). PNS is a group of disorders that are caused by the immune system attacking healthy cells in the nervous system. Hu-PARAs are one of the most common types of autoantibodies associated with PNS, and they are often found in patients with cancer of the breast, lung, and ovaries. When Hu-PARAs bind to neural tissue, they can cause inflammation and damage to the nervous system, leading to a range of symptoms such as weakness, numbness, and cognitive impairment. In some cases, Hu-PARAs can also cause more severe neurological symptoms such as seizures, vision loss, and paralysis. Diagnosis of Hu-PARA-associated PNS typically involves the detection of the autoantibodies in the patient's blood or cerebrospinal fluid, as well as imaging studies to identify any abnormalities in the nervous system. Treatment for Hu-PARA-associated PNS typically involves the use of immunosuppressive medications to reduce the activity of the immune system and prevent further damage to the nervous system.
Antibodies, viral, are proteins produced by the immune system in response to a viral infection. They are also known as immunoglobulins or antibodies. Viral antibodies are specific to a particular virus and can help to neutralize and eliminate the virus from the body. They are typically detected in the blood or other bodily fluids using laboratory tests, such as enzyme-linked immunosorbent assays (ELISAs) or immunofluorescence assays. The presence of viral antibodies can be used as a diagnostic tool to confirm a viral infection or to determine the immune status of an individual.
CD80 is a protein that is expressed on the surface of certain cells in the immune system, including antigen-presenting cells (APCs) such as dendritic cells and macrophages. CD80 is also known as B7-1, and it plays a critical role in the activation of T cells, which are a type of immune cell that helps to fight off infections and diseases. When an APC encounters a pathogen, it engulfs the pathogen and processes its antigens, which are small pieces of the pathogen that can be recognized by the immune system. The APC then presents these antigens on its surface, along with the CD80 protein, to T cells. This interaction between the APC and the T cell is a key step in the activation of the T cell, which then becomes activated and begins to divide and differentiate into effector T cells that can directly attack the pathogen or into memory T cells that can provide long-term protection against future infections by the same pathogen. Antigens, CD80 are often used in medical research and as a tool for developing vaccines and other immune-based therapies. They can be used to stimulate the immune system to recognize and attack specific pathogens or cancer cells, or they can be used to suppress the immune system in cases where it is overactive or causing autoimmune diseases.
Monoclonal antibodies (mAbs) are laboratory-made proteins that can mimic the immune system's ability to fight off harmful pathogens, such as viruses and bacteria. They are produced by genetically engineering cells to produce large quantities of a single type of antibody, which is specific to a particular antigen (a molecule that triggers an immune response). In the medical field, monoclonal antibodies are used to treat a variety of conditions, including cancer, autoimmune diseases, and infectious diseases. They can be administered intravenously, intramuscularly, or subcutaneously, depending on the condition being treated. Monoclonal antibodies work by binding to specific antigens on the surface of cells or pathogens, marking them for destruction by the immune system. They can also block the activity of specific molecules involved in disease processes, such as enzymes or receptors. Overall, monoclonal antibodies have revolutionized the treatment of many diseases, offering targeted and effective therapies with fewer side effects than traditional treatments.
Autoantibodies are antibodies that are produced by the immune system against the body's own cells, tissues, or organs. In other words, they are antibodies that mistakenly target and attack the body's own components instead of foreign invaders like viruses or bacteria. Autoantibodies can be present in people with various medical conditions, including autoimmune diseases such as rheumatoid arthritis, lupus, and multiple sclerosis. They can also be found in people with certain infections, cancer, and other diseases. Autoantibodies can cause damage to the body's own cells, tissues, or organs, leading to inflammation, tissue destruction, and other symptoms. They can also interfere with the normal functioning of the body's systems, such as the nervous system, digestive system, and cardiovascular system. Diagnosis of autoantibodies is typically done through blood tests, which can detect the presence of specific autoantibodies in the blood. Treatment for autoimmune diseases that involve autoantibodies may include medications to suppress the immune system, such as corticosteroids or immunosuppressants, as well as other therapies to manage symptoms and prevent complications.

It is a part of the major histocompatibility complex (MHC) and plays a crucial role in the immune response to infections and other foreign substances. The HLA-DR2 Antigen is specifically associated with the HLA-DR2 gene, which is located on chromosome 6. This gene codes for a protein called the HLA-DR2 molecule, which is composed of two subunits: a heavy chain and a light chain. The HLA-DR2 Antigen is expressed on the surface of antigen-presenting cells (APCs), such as dendritic cells and macrophages, where it can bind to foreign antigens and present them to T cells. This process is a key step in the activation of the immune response and the elimination of pathogens from the body. In addition to its role in the immune response, the HLA-DR2 Antigen has also been associated with certain autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis. In these conditions, the immune system mistakenly attacks healthy cells and tissues, leading to inflammation and damage.
Myelitis is a medical condition characterized by inflammation of the spinal cord, which is a bundle of nerves that runs from the brain down through the back of the neck and back to the pelvis. The inflammation can cause damage to the spinal cord, leading to a range of symptoms, including pain, weakness, numbness, and tingling sensations in the affected area. Myelitis can be caused by a variety of factors, including infections, autoimmune disorders, and certain medications. Some common causes of myelitis include viral infections such as herpes simplex virus, West Nile virus, and poliovirus, as well as bacterial infections such as tuberculosis and Lyme disease. Autoimmune disorders such as multiple sclerosis and neuromyelitis optica can also cause myelitis. The symptoms of myelitis can vary depending on the location and severity of the inflammation. In some cases, the symptoms may be mild and resolve on their own, while in other cases, they can be severe and require medical treatment. Treatment for myelitis typically involves managing symptoms and addressing the underlying cause of the inflammation. This may include medications, physical therapy, and other supportive care.
Interleukin-12 (IL-12) is a cytokine that plays a critical role in the immune response to infections and cancer. It is produced by activated immune cells, such as macrophages and dendritic cells, and acts on other immune cells, such as natural killer cells and T cells, to enhance their ability to kill pathogens and tumor cells. IL-12 is a heterodimeric cytokine composed of two subunits, p35 and p40, which are encoded by separate genes. The p35 subunit is responsible for the biological activity of IL-12, while the p40 subunit is shared with other cytokines, such as IL-23 and IL-27. IL-12 has several important functions in the immune system. It promotes the differentiation of naive T cells into Th1 cells, which produce IFN-γ and other pro-inflammatory cytokines that are important for the clearance of intracellular pathogens, such as viruses and bacteria. IL-12 also enhances the activity of natural killer cells, which are important for the elimination of tumor cells and virally infected cells. In addition to its role in innate and adaptive immunity, IL-12 has been implicated in the pathogenesis of several autoimmune diseases, such as multiple sclerosis and psoriasis, and has been studied as a potential therapeutic agent for cancer and infectious diseases.

Treatment for chronic diseases may also involve rehabilitation, physical therapy, and other supportive care.
Chemokines are a family of small signaling proteins that play a crucial role in the immune system. They are produced by various cells in response to infection, injury, or inflammation and act as chemical messengers to attract immune cells to the site of injury or infection. Chemokines bind to specific receptors on the surface of immune cells, such as neutrophils, monocytes, and lymphocytes, and guide them to the site of infection or injury. They also play a role in regulating the migration and activation of immune cells within tissues. In the medical field, chemokines are important for understanding and treating various diseases, including cancer, autoimmune disorders, and infectious diseases. They are also being studied as potential therapeutic targets for the development of new drugs to treat these conditions.
In the medical field, RNA, Messenger (mRNA) refers to a type of RNA molecule that carries genetic information from DNA in the nucleus of a cell to the ribosomes, where proteins are synthesized. During the process of transcription, the DNA sequence of a gene is copied into a complementary RNA sequence called messenger RNA (mRNA). This mRNA molecule then leaves the nucleus and travels to the cytoplasm of the cell, where it binds to ribosomes and serves as a template for the synthesis of a specific protein. The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein that is synthesized. Therefore, changes in the sequence of nucleotides in the mRNA molecule can result in changes in the amino acid sequence of the protein, which can affect the function of the protein and potentially lead to disease. mRNA molecules are often used in medical research and therapy as a way to introduce new genetic information into cells. For example, mRNA vaccines work by introducing a small piece of mRNA that encodes for a specific protein, which triggers an immune response in the body.
Hypersensitivity, delayed, also known as type IV hypersensitivity or cell-mediated hypersensitivity, is a type of immune response that occurs after an initial exposure to a foreign substance, such as a protein or a drug. Unlike immediate hypersensitivity, which occurs within minutes or hours of exposure, delayed hypersensitivity takes several days to develop. In delayed hypersensitivity, immune cells called T cells recognize and remember the foreign substance. When the immune system encounters the same substance again, the T cells become activated and release chemicals that cause inflammation and damage to the tissue where the substance is located. This can lead to symptoms such as redness, swelling, and itching, and in severe cases, can cause tissue damage or even organ failure. Delayed hypersensitivity is often associated with allergic reactions to certain drugs, metals, or chemicals, as well as with certain infections, such as tuberculosis and leprosy. It is also a key component of the immune response to transplanted organs, as the immune system recognizes the foreign tissue and mounts an attack against it.
Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of foreign substances, such as viruses, bacteria, and other pathogens. Antibodies are designed to recognize and bind to specific molecules on the surface of these foreign substances, marking them for destruction by other immune cells. There are five main classes of antibodies: IgG, IgA, IgM, IgD, and IgE. Each class of antibody has a unique structure and function, and they are produced by different types of immune cells in response to different types of pathogens. Antibodies play a critical role in the immune response, helping to protect the body against infection and disease. They can neutralize pathogens by binding to them and preventing them from entering cells, or they can mark them for destruction by other immune cells. In some cases, antibodies can also help to stimulate the immune response by activating immune cells or by recruiting other immune cells to the site of infection. Antibodies are often used in medical treatments, such as in the development of vaccines, where they are used to stimulate the immune system to produce a response to a specific pathogen. They are also used in diagnostic tests to detect the presence of specific pathogens or to monitor the immune response to a particular treatment.
Membrane glycoproteins are proteins that are attached to the cell membrane through a glycosyl group, which is a complex carbohydrate. These proteins play important roles in cell signaling, cell adhesion, and cell recognition. They are involved in a wide range of biological processes, including immune response, cell growth and differentiation, and nerve transmission. Membrane glycoproteins can be classified into two main types: transmembrane glycoproteins, which span the entire cell membrane, and peripheral glycoproteins, which are located on one side of the membrane.
Interleukins are a group of signaling proteins that are produced by various cells of the immune system, including white blood cells, and play a crucial role in regulating immune responses. They are also involved in a wide range of other physiological processes, such as cell growth, differentiation, and apoptosis (programmed cell death).

Some of the most well-known interleukins include interleukin-1 (IL-1), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-12 (IL-12). Interleukins can act locally within tissues or be transported through the bloodstream to other parts of the body. They can also bind to specific receptors on the surface of target cells, triggering a signaling cascade that leads to changes in gene expression and cellular function. In the medical field, interleukins are often used as therapeutic agents to treat a variety of conditions, including autoimmune diseases, cancer, and infections. They can also be used as diagnostic tools to help identify and monitor certain diseases.
Central Nervous System Viral Diseases (CNSVDs) are infections caused by viruses that affect the brain and spinal cord. These viruses can enter the central nervous system (CNS) through various routes, such as the bloodstream, respiratory system, or mucous membranes. CNSVDs can cause a range of symptoms, including fever, headache, nausea, vomiting, confusion, seizures, and paralysis. Some viruses can also cause more severe neurological complications, such as meningitis, encephalitis, or Guillain-Barré syndrome. Examples of viruses that can cause CNSVDs include herpes simplex virus, varicella-zoster virus, West Nile virus, Japanese encephalitis virus, dengue virus, and Zika virus. Treatment for CNSVDs typically involves antiviral medications, supportive care, and management of symptoms. In some cases, hospitalization may be necessary for severe cases or complications.
Gliosis is a term used in the medical field to describe the process of scar tissue formation in the brain or spinal cord. It occurs when there is damage to the central nervous system (CNS) due to injury, infection, or disease. During gliosis, astrocytes, a type of glial cell, become activated and proliferate, forming a scar tissue called gliosis. This scar tissue helps to protect the surrounding healthy tissue and limit the spread of damage. However, it can also interfere with the normal functioning of the CNS and contribute to the development of neurological disorders. Gliosis can be classified into two types: reactive gliosis and neoplastic gliosis. Reactive gliosis is a normal response to injury or disease, while neoplastic gliosis refers to the abnormal proliferation of astrocytes that can lead to the development of gliomas, a type of brain tumor.
In the medical field, recurrence refers to the reappearance of a disease or condition after it has been treated or has gone into remission. Recurrence can occur in various medical conditions, including cancer, infections, and autoimmune diseases. For example, in cancer, recurrence means that the cancer has come back after it has been treated with surgery, chemotherapy, radiation therapy, or other treatments. Recurrence can occur months, years, or even decades after the initial treatment. In infections, recurrence means that the infection has returned after it has been treated with antibiotics or other medications. Recurrence can occur due to incomplete treatment, antibiotic resistance, or other factors. In autoimmune diseases, recurrence means that the symptoms of the disease return after they have been controlled with medication. Recurrence can occur due to changes in the immune system or other factors. Overall, recurrence is a significant concern for patients and healthcare providers, as it can require additional treatment and can impact the patient's quality of life.
Tumor Necrosis Factor-alpha (TNF-alpha) is a cytokine, a type of signaling protein, that plays a crucial role in the immune response and inflammation. It is produced by various cells in the body, including macrophages, monocytes, and T cells, in response to infection, injury, or other stimuli. TNF-alpha has multiple functions in the body, including regulating the immune response, promoting cell growth and differentiation, and mediating inflammation. It can also induce programmed cell death, or apoptosis, in some cells, which can be beneficial in fighting cancer. However, excessive or prolonged TNF-alpha production can lead to chronic inflammation and tissue damage, which can contribute to the development of various diseases, including autoimmune disorders, inflammatory bowel disease, and certain types of cancer. In the medical field, TNF-alpha is often targeted in the treatment of these conditions. For example, drugs called TNF inhibitors, such as infliximab and adalimumab, are used to block the action of TNF-alpha and reduce inflammation in patients with rheumatoid arthritis, Crohn's disease, and other inflammatory conditions.
Paraneoplastic syndromes are a group of medical conditions that are not directly caused by the cancer itself, but rather by the body's immune response to the cancer. These conditions can occur in association with various types of cancer, including lung cancer, breast cancer, and ovarian cancer, among others. Paraneoplastic syndromes can affect various organs and systems in the body, including the nervous system, the endocrine system, the skin, and the muscles. Some common examples of paraneoplastic syndromes include: * Cushing's syndrome, which is caused by the overproduction of cortisol due to a tumor in the pituitary gland or adrenal gland. * Hypercalcemia, which is caused by the overproduction of parathyroid hormone due to a tumor in the parathyroid gland. * Pemphigus vulgaris, which is a skin disorder caused by an autoimmune response to the body's own cells. * Myasthenia gravis, which is a neuromuscular disorder caused by an autoimmune response to the body's own acetylcholine receptors. Paraneoplastic syndromes can be difficult to diagnose and treat, as they are not directly caused by the cancer. However, they can provide important clues to the presence of cancer, and can sometimes be used to help diagnose the type and location of the cancer. Treatment for paraneoplastic syndromes typically involves managing the symptoms and addressing the underlying cause, which may be the cancer itself.
Interleukin-23 (IL-23) is a cytokine that plays a critical role in the regulation of the immune system. It is composed of two subunits, p19 and p40, which are encoded by separate genes. The p19 subunit is a 19-kilodalton protein that is responsible for binding to the IL-23 receptor on the surface of immune cells, such as T cells and dendritic cells. Activation of the IL-23 receptor by the p19 subunit leads to the production of other cytokines, such as IL-17 and IL-22, which are involved in the regulation of immune responses. In the medical field, the p19 subunit is often studied as a potential target for the treatment of autoimmune diseases, such as psoriasis and inflammatory bowel disease, as well as for the prevention and treatment of cancer.
Viral vaccines are a type of vaccine that use a weakened or inactivated form of a virus to stimulate the immune system to produce an immune response against the virus. This immune response can provide protection against future infections with the virus. There are several different types of viral vaccines, including live attenuated vaccines, inactivated vaccines, and subunit vaccines. Live attenuated vaccines use a weakened form of the virus that is still able to replicate, but is not strong enough to cause disease. Inactivated vaccines use a killed form of the virus that is no longer able to replicate. Subunit vaccines use only a small part of the virus, such as a protein or a piece of genetic material, to stimulate an immune response. Viral vaccines are used to prevent a wide range of viral diseases, including influenza, measles, mumps, rubella, polio, hepatitis A and B, and human papillomavirus (HPV). They are typically given by injection, but can also be given by mouth or nose in some cases. Viral vaccines are an important tool in preventing the spread of viral diseases and reducing the number of cases and deaths caused by these diseases. They are generally safe and effective, and are an important part of public health efforts to control the spread of viral diseases.
Cuprizone is a copper chelating agent that is used in the medical field as an experimental tool to induce demyelination in the central nervous system. It is commonly used in animal models of multiple sclerosis (MS) to study the disease process and potential treatments. In humans, cuprizone is not used as a therapeutic agent and is only administered under controlled conditions in clinical trials. When given orally, cuprizone selectively accumulates in the liver and exerts its effects by chelating copper ions, leading to a deficiency of copper in the brain. This copper deficiency causes damage to oligodendrocytes, the cells responsible for producing myelin, the protective sheath around nerve fibers. The resulting demyelination in the brain leads to a range of neurological symptoms, including gait abnormalities, loss of coordination, and cognitive impairment. These symptoms are similar to those seen in MS, making cuprizone a useful tool for studying the disease and testing potential treatments.
Chemokine CCL2, also known as monocyte chemoattractant protein-1 (MCP-1), is a small protein that plays a crucial role in the immune system. It is a member of the chemokine family of proteins, which are responsible for regulating the movement of immune cells within the body. CCL2 is primarily produced by cells such as monocytes, macrophages, and endothelial cells in response to inflammatory stimuli. It functions as a chemoattractant, drawing immune cells towards the site of inflammation or infection. Specifically, CCL2 attracts monocytes and T cells to the site of injury or infection, where they can help to clear the infection and promote tissue repair. In addition to its role in immune cell recruitment, CCL2 has also been implicated in a variety of other physiological processes, including angiogenesis (the formation of new blood vessels), tissue repair, and cancer progression. Dysregulation of CCL2 expression or function has been linked to a number of diseases, including atherosclerosis, diabetes, and certain types of cancer.
Interleukin-2 (IL-2) is a cytokine, a type of signaling molecule that plays a crucial role in the immune system. It is produced by activated T cells, a type of white blood cell that plays a central role in the body's defense against infection and disease. IL-2 has several important functions in the immune system. It promotes the growth and differentiation of T cells, which helps to increase the number of immune cells available to fight infection. It also stimulates the production of other cytokines, which can help to amplify the immune response. IL-2 is used in the treatment of certain types of cancer, such as melanoma and kidney cancer. It works by stimulating the immune system to attack cancer cells. It is typically given as an injection or infusion, and can cause side effects such as fever, chills, and flu-like symptoms. In addition to its use in cancer treatment, IL-2 has also been studied for its potential role in treating other conditions, such as autoimmune diseases and viral infections.
CD274, also known as programmed death-ligand 1 (PD-L1), is a protein that plays a role in the immune system's response to infections and cancer. It is expressed on the surface of certain cells, including cancer cells, and interacts with the PD-1 protein on the surface of T cells to inhibit their activity. This interaction can prevent the immune system from attacking and eliminating cancer cells. In recent years, PD-L1 has become an important target for cancer immunotherapy, with drugs that block the interaction between PD-L1 and PD-1 being developed to help the immune system recognize and attack cancer cells.
Paraneoplastic polyneuropathy (PNP) is a type of peripheral neuropathy that is caused by a reaction to a cancerous tumor in the body. It is a rare condition that affects the nerves that control movement, sensation, and other functions in the body. PNP can occur in association with a variety of different types of cancer, including lung cancer, breast cancer, and ovarian cancer. The symptoms of PNP can vary depending on which nerves are affected, but may include weakness, numbness, tingling, and pain in the affected areas. Treatment for PNP typically involves managing the underlying cancer and addressing the symptoms of the neuropathy.
Arbovirus infections are a group of viral diseases that are transmitted to humans and animals through the bite of infected arthropod vectors, such as mosquitoes, ticks, and fleas. The term "arbovirus" is derived from the words "arthropod-borne virus." There are many different types of arboviruses, including dengue, Zika, chikungunya, West Nile virus, Japanese encephalitis virus, and tick-borne encephalitis virus. These viruses can cause a range of symptoms, from mild fever and rash to more severe illness, such as meningitis, encephalitis, and hemorrhagic fever. Arbovirus infections are typically found in tropical and subtropical regions, but they can also occur in temperate regions during the summer months when the vectors are most active. Prevention measures include avoiding mosquito bites by using insect repellent, wearing protective clothing, and eliminating standing water where mosquitoes can breed. Vaccines are available for some arboviruses, such as Japanese encephalitis and yellow fever, but not for all. Treatment is typically supportive, focusing on managing symptoms and preventing complications.

As with any medical product, it is important to use propylene glycols-containing products as directed by a healthcare professional and to report any adverse reactions to your healthcare provider.
Interferon-beta (IFN-beta) is a type of cytokine that is naturally produced by the body's immune system in response to viral infections. It is also used as a medication to treat certain autoimmune diseases, such as multiple sclerosis (MS), by reducing inflammation and slowing the progression of the disease. IFN-beta is typically administered as an injection or infusion, and its effects can last for several days. It works by activating immune cells and inhibiting the growth of virus-infected cells. In MS, IFN-beta is thought to reduce the frequency and severity of relapses by modulating the immune response and reducing inflammation in the central nervous system. There are several different types of IFN-beta available, including beta-1a, beta-1b, and beta-2a. These different forms of IFN-beta have slightly different mechanisms of action and are used in different ways to treat MS and other autoimmune diseases.
Neuromyelitis optica (NMO) is a rare autoimmune disorder that affects the central nervous system, specifically the optic nerves and spinal cord. It is characterized by episodes of severe optic neuritis (inflammation of the optic nerve) and transverse myelitis (inflammation of the spinal cord). The symptoms of NMO can include vision loss, pain or numbness in the limbs, difficulty walking, and bladder or bowel problems. The disease can be very debilitating and can lead to permanent disability if left untreated. NMO is caused by the immune system attacking the protective covering of the nerves, called myelin. This can disrupt the normal functioning of the nerves and lead to the symptoms associated with the disease. Diagnosis of NMO typically involves a combination of clinical examination, imaging studies, and laboratory tests. Treatment typically involves the use of immunosuppressive medications to reduce inflammation and prevent further damage to the nerves.
Methylprednisolone is a synthetic glucocorticoid hormone that is used in the medical field to treat a variety of conditions. It is a potent anti-inflammatory and immunosuppressive agent that is commonly used to reduce inflammation and swelling, as well as to suppress the immune system.

Tuftsin has been shown to have immune-stimulating properties and has been used in the treatment of various infections, including bacterial, viral, and fungal infections. It is also being studied for its potential use in the treatment of cancer and other diseases.
Genetic predisposition to disease refers to the tendency of an individual to develop a particular disease or condition due to their genetic makeup. It means that certain genes or combinations of genes increase the risk of developing a particular disease or condition. Genetic predisposition to disease is not the same as having the disease itself. It simply means that an individual has a higher likelihood of developing the disease compared to someone without the same genetic predisposition. Genetic predisposition to disease can be inherited from parents or can occur due to spontaneous mutations in genes. Some examples of genetic predisposition to disease include hereditary breast and ovarian cancer, Huntington's disease, cystic fibrosis, and sickle cell anemia. Understanding genetic predisposition to disease is important in medical practice because it can help identify individuals who are at high risk of developing a particular disease and allow for early intervention and prevention strategies to be implemented.
RNA, Viral refers to the genetic material of viruses that are composed of RNA instead of DNA. Viral RNA is typically single-stranded and can be either positive-sense or negative-sense. Positive-sense RNA viruses can be directly translated into proteins by the host cell's ribosomes, while negative-sense RNA viruses require a complementary positive-sense RNA intermediate before protein synthesis can occur. Viral RNA is often encapsidated within a viral capsid and can be further protected by an envelope made of lipids and proteins derived from the host cell. RNA viruses include a wide range of pathogens that can cause diseases in humans and other organisms, such as influenza, hepatitis C, and SARS-CoV-2 (the virus responsible for COVID-19).
Neuritis, autoimmune, experimental refers to a type of inflammation of the nerves that is caused by an autoimmune response, which is when the body's immune system mistakenly attacks its own healthy cells and tissues. This type of neuritis is typically studied in experimental settings, such as in laboratory animals or in clinical trials, in order to better understand the underlying mechanisms of the disease and to develop new treatments. It is important to note that this type of neuritis is not yet a recognized or well-understood condition in humans, and more research is needed to fully understand its causes and potential treatments.
Transforming Growth Factor beta (TGF-β) is a family of cytokines that play a crucial role in regulating cell growth, differentiation, and migration. TGF-βs are secreted by a variety of cells, including immune cells, fibroblasts, and epithelial cells, and act on neighboring cells to modulate their behavior. TGF-βs have both pro-inflammatory and anti-inflammatory effects, depending on the context in which they are released. They can promote the differentiation of immune cells into effector cells that help to fight infections, but they can also suppress the immune response to prevent excessive inflammation. In addition to their role in immune regulation, TGF-βs are also involved in tissue repair and fibrosis. They can stimulate the production of extracellular matrix proteins, such as collagen, which are essential for tissue repair. However, excessive production of TGF-βs can lead to fibrosis, a condition in which excessive amounts of connective tissue accumulate in the body, leading to organ dysfunction. Overall, TGF-βs are important signaling molecules that play a critical role in regulating a wide range of cellular processes in the body.
Anaphylaxis is a severe and potentially life-threatening allergic reaction that occurs rapidly after exposure to an allergen. It is a systemic reaction that affects multiple body systems, including the respiratory, cardiovascular, and gastrointestinal systems. The symptoms of anaphylaxis can develop within minutes of exposure to an allergen and can include: - Hives or welts on the skin - Swelling of the face, lips, tongue, or throat - Difficulty breathing or wheezing - Rapid or weak pulse - Drop in blood pressure - Nausea or vomiting - Dizziness or fainting Anaphylaxis is a medical emergency that requires immediate treatment with epinephrine (also known as adrenaline) and other medications to counteract the symptoms and prevent further complications. If left untreated, anaphylaxis can lead to respiratory failure, cardiac arrest, and death.
Immunoglobulin G (IgG) is a type of protein that is produced by the immune system in response to the presence of foreign substances, such as bacteria, viruses, and toxins. It is the most abundant type of immunoglobulin in the blood and is responsible for the majority of the body's defense against infections. IgG is produced by B cells, which are a type of white blood cell that plays a key role in the immune response. When a B cell encounters a foreign substance, it produces IgG antibodies that can recognize and bind to the substance, marking it for destruction by other immune cells. IgG antibodies can also be transferred from mother to child through the placenta during pregnancy, providing the baby with some protection against infections during the first few months of life. In addition, some vaccines contain IgG antibodies to help stimulate the immune system and provide protection against specific diseases. Overall, IgG is an important component of the immune system and plays a critical role in protecting the body against infections and diseases.
Autoimmune diseases of the nervous system are a group of disorders in which the immune system mistakenly attacks healthy cells and tissues in the nervous system. These diseases can affect any part of the nervous system, including the brain, spinal cord, peripheral nerves, and autonomic nervous system. Examples of autoimmune diseases of the nervous system include multiple sclerosis (MS), Guillain-Barré syndrome (GBS), myasthenia gravis (MG), and lupus erythematosus (LE). These diseases can cause a range of symptoms, including muscle weakness, numbness, tingling, pain, difficulty with coordination and balance, vision problems, and cognitive impairment. The exact cause of autoimmune diseases of the nervous system is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Treatment typically involves medications to suppress the immune system and manage symptoms, as well as physical therapy and other supportive care.
CD86 is a protein that is expressed on the surface of certain immune cells, including dendritic cells and B cells. It is a member of the B7 family of proteins, which play a key role in regulating the immune response. CD86 is involved in the activation of T cells, which are a type of immune cell that plays a central role in the body's defense against infection and disease. When dendritic cells present an antigen (a foreign substance that triggers an immune response) to a T cell, they also express CD86 on their surface. This allows the T cell to recognize the antigen and become activated, leading to the production of immune cells that can attack and destroy the invading pathogen. In addition to its role in activating T cells, CD86 has also been shown to play a role in the regulation of the immune response. For example, it has been shown to promote the differentiation of regulatory T cells, which are a type of immune cell that helps to prevent autoimmune diseases by suppressing the activity of other immune cells. Overall, CD86 is an important protein in the immune system that plays a role in both the activation and regulation of immune responses.
Recombinant fusion proteins are proteins that are produced by combining two or more genes in a single molecule. These proteins are typically created using genetic engineering techniques, such as recombinant DNA technology, to insert one or more genes into a host organism, such as bacteria or yeast, which then produces the fusion protein. Fusion proteins are often used in medical research and drug development because they can have unique properties that are not present in the individual proteins that make up the fusion. For example, a fusion protein might be designed to have increased stability, improved solubility, or enhanced targeting to specific cells or tissues. Recombinant fusion proteins have a wide range of applications in medicine, including as therapeutic agents, diagnostic tools, and research reagents. Some examples of recombinant fusion proteins used in medicine include antibodies, growth factors, and cytokines.

It is a subunit of the cytokine interleukin-12 (IL-12), which is produced by immune cells such as macrophages and dendritic cells in response to infections or other inflammatory stimuli. IL-12 is a heterodimeric cytokine composed of two subunits, p35 and p40. The p35 subunit is encoded by the "IL12B" gene and is responsible for the biological activity of IL-12. IL-12p35 is a type I interferon-stimulating factor that promotes the differentiation of T cells into Th1 cells, which are involved in cell-mediated immunity against intracellular pathogens such as viruses and bacteria. In addition to its role in T cell differentiation, IL-12p35 also plays a role in the regulation of innate immune responses. It can stimulate the production of other pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), and can also enhance the activity of natural killer (NK) cells. Disruptions in the regulation of IL-12p35 signaling have been implicated in a number of autoimmune and inflammatory diseases, including multiple sclerosis, psoriasis, and inflammatory bowel disease.
CD11b is a type of protein found on the surface of certain immune cells, such as neutrophils and monocytes. It is a member of the integrin family of proteins, which are involved in cell adhesion and signaling. CD11b is also known as the alpha chain of the integrin receptor Mac-1 (Macrophage-1 antigen). Antigens, CD11b are molecules that bind to CD11b on the surface of immune cells. These antigens can be foreign substances, such as bacteria or viruses, or they can be self-molecules that have been altered in some way. When CD11b binds to an antigen, it triggers a series of signaling events that activate the immune cell and cause it to respond to the presence of the antigen. This response can include the production of inflammatory molecules, the recruitment of other immune cells to the site of the antigen, and the destruction of the antigen. CD11b and its antigens play an important role in the immune response and are the subject of ongoing research in the field of immunology.
Multiple Sclerosis, Relapsing-Remitting (MS-RR) is a type of multiple sclerosis (MS), a chronic autoimmune disorder that affects the central nervous system (CNS), which includes the brain, spinal cord, and optic nerves. In MS-RR, the disease is characterized by episodes of relapse or flare-ups, followed by periods of remission or recovery. During a relapse, symptoms of MS may worsen or new symptoms may appear, such as muscle weakness, numbness, tingling, difficulty walking, double vision, and fatigue. These symptoms can last for days to weeks and may be accompanied by inflammation in the brain or spinal cord. During remission, symptoms may improve or disappear altogether, and the individual may return to their normal activities. However, the disease can continue to progress over time, leading to permanent disability and cognitive impairment. MS-RR is the most common form of MS, accounting for about 85% of all cases. Treatment for MS-RR typically involves medications that can reduce the frequency and severity of relapses, slow disease progression, and manage symptoms.
Bunyaviridae infections refer to a group of viral infections caused by viruses belonging to the Bunyaviridae family. These viruses are enveloped RNA viruses that can infect a wide range of hosts, including humans, animals, and insects. The Bunyaviridae family is divided into several genera, including Orthobunyavirus, Hantavirus, Nairovirus, Tospovirus, and Phlebovirus. Each genus contains a variety of viruses that can cause different types of infections in humans and animals. Some of the most well-known bunyaviruses include the Rift Valley fever virus, which can cause severe fever and hemorrhagic fever in humans and animals, and the Crimean-Congo hemorrhagic fever virus, which can cause severe bleeding and organ failure in humans. Bunyaviridae infections can be transmitted through a variety of routes, including bites from infected insects, contact with infected bodily fluids, or inhalation of infected aerosols. Symptoms of bunyaviridae infections can range from mild to severe and may include fever, headache, muscle aches, nausea, vomiting, and diarrhea. Treatment for bunyaviridae infections typically involves supportive care to manage symptoms and prevent complications. In some cases, antiviral medications may be used to treat the infection. Vaccines are also available for some bunyaviruses, such as the Rift Valley fever vaccine.
Interleukin-9 (IL-9) is a cytokine, a type of signaling molecule, that plays a role in the immune system. It is produced by various types of immune cells, including T cells, mast cells, and basophils, and acts on other immune cells to regulate their activity. IL-9 has several functions in the immune system. It promotes the growth and differentiation of T cells, particularly those that are involved in fighting infections and allergies. It also stimulates the production of antibodies by B cells, which are cells that produce antibodies to help fight infections. IL-9 has been implicated in several autoimmune diseases, such as asthma, rheumatoid arthritis, and multiple sclerosis, as well as in some types of cancer. It is also being studied as a potential therapeutic target for these conditions.
STAT4 (Signal Transducer and Activator of Transcription 4) is a transcription factor that plays a crucial role in the regulation of immune responses and inflammation. It is a member of the STAT family of proteins, which are involved in transmitting signals from the cell surface to the nucleus in response to various cytokines and growth factors. In the context of the immune system, STAT4 is activated by the cytokine interleukin-12 (IL-12) and its receptor, and it plays a key role in the differentiation of T helper 1 (Th1) cells, which are important for the immune response against intracellular pathogens such as viruses and bacteria. STAT4 also regulates the expression of genes involved in the production of pro-inflammatory cytokines and chemokines, which recruit immune cells to sites of infection or inflammation. In addition to its role in the immune system, STAT4 has been implicated in the pathogenesis of several autoimmune diseases, including rheumatoid arthritis, systemic lupus erythematosus, and psoriasis. Mutations in the STAT4 gene have been associated with an increased risk of these diseases, and STAT4 inhibitors are being investigated as potential therapeutic agents for the treatment of autoimmune disorders.
Receptors, Chemokine are proteins found on the surface of cells that bind to specific chemokines, which are small signaling molecules that play a role in immune cell trafficking and inflammation. These receptors are involved in the regulation of immune cell migration and are important for the recruitment of immune cells to sites of infection or injury. There are several different types of chemokine receptors, each of which is specific to a particular chemokine or group of chemokines. Dysregulation of chemokine receptors has been implicated in a variety of diseases, including cancer, autoimmune disorders, and infectious diseases.
DNA vaccines are a type of vaccine that uses a small piece of genetic material, usually DNA, to stimulate an immune response in the body. This genetic material is designed to encode a specific protein that is found on the surface of a pathogen, such as a virus or bacteria. When the DNA is introduced into the body, it is taken up by cells and used to produce the protein. The immune system recognizes the protein as foreign and mounts an immune response against it, which can provide protection against future infections by the pathogen. DNA vaccines are still in the experimental stage and have not yet been widely used in humans. However, they have shown promise in preclinical studies and are being investigated as a potential way to prevent a variety of infectious diseases, including influenza, HIV, and malaria. One advantage of DNA vaccines is that they can be easily and quickly produced, and they do not require the use of live or attenuated pathogens, which can be more difficult to work with and may pose a risk of causing disease.
Meningoencephalitis is a medical condition that refers to the inflammation of both the meninges, which are the protective membranes that surround the brain and spinal cord, and the brain itself. This inflammation can be caused by a variety of factors, including viral or bacterial infections, autoimmune disorders, or certain medications. Symptoms of meningoencephalitis can include fever, headache, nausea and vomiting, sensitivity to light, confusion, seizures, and changes in mental status. In severe cases, meningoencephalitis can lead to coma or even death. Diagnosis of meningoencephalitis typically involves a combination of physical examination, medical history, and laboratory tests, such as blood tests, cerebrospinal fluid analysis, and imaging studies like MRI or CT scans. Treatment for meningoencephalitis depends on the underlying cause and can include antiviral or antibiotic medications, corticosteroids to reduce inflammation, and supportive care to manage symptoms and prevent complications. In some cases, hospitalization and intensive care may be necessary.
Stiff-Person Syndrome (SPS) is a rare autoimmune disorder that affects the nervous system. It is characterized by muscle stiffness and spasms, particularly in the trunk and limbs, which can be triggered by emotional stress or physical stimuli. SPS can also cause a variety of other symptoms, including muscle weakness, fatigue, and joint pain. The stiffness and spasms can be so severe that they can interfere with daily activities and make it difficult to walk or perform other basic tasks. SPS is a lifelong condition, but treatment can help manage symptoms and improve quality of life.
CD4 antigens, also known as CD4 molecules, are a type of protein found on the surface of certain cells in the immune system. These cells, called T cells, play a crucial role in the body's defense against infection and disease. CD4 antigens are specifically associated with helper T cells, which are a type of T cell that works to coordinate the immune response by activating other immune cells. Helper T cells express high levels of CD4 antigens on their surface, which allows them to bind to and activate other immune cells, such as B cells and macrophages. In the context of the human immunodeficiency virus (HIV), the virus specifically targets and destroys CD4+ T cells, leading to a weakened immune system and an increased susceptibility to opportunistic infections and certain types of cancer. Therefore, CD4+ T cell count is often used as a key indicator of HIV infection and disease progression.
Immune sera refers to a type of blood serum that contains antibodies produced by the immune system in response to an infection or vaccination. These antibodies are produced by B cells, which are a type of white blood cell that plays a key role in the immune response. Immune sera can be used to diagnose and treat certain infections, as well as to prevent future infections. For example, immune sera containing antibodies against a specific virus or bacteria can be used to diagnose a current infection or to prevent future infections in people who have been exposed to the virus or bacteria. Immune sera can also be used as a research tool to study the immune response to infections and to develop new vaccines and treatments. In some cases, immune sera may be used to treat patients with severe infections or allergies, although this is less common than using immune sera for diagnostic or preventive purposes.
Ovalbumin is a protein found in egg whites. It is a major allergen and can cause allergic reactions in some people. In the medical field, ovalbumin is often used as a model antigen for studying allergic reactions and for developing allergy vaccines. It is also used in research to study the structure and function of proteins, as well as in the production of various medical products, such as diagnostic reagents and pharmaceuticals.
CD28 is a protein found on the surface of T cells, a type of white blood cell that plays a central role in the immune system. CD28 is a co-stimulatory molecule, meaning that it works together with other molecules to help activate and regulate T cells. Antigens, CD28 refers to molecules that bind to the CD28 protein on T cells and activate them. These antigens are typically found on the surface of other cells, such as infected cells or cancer cells, and are recognized by T cells as foreign or abnormal. When a T cell encounters an antigen that binds to its CD28 receptor, it becomes activated and begins to divide and produce more T cells, which can then attack and destroy the infected or cancerous cells. CD28-based antigens are being studied as potential targets for immunotherapy, a type of cancer treatment that uses the body's own immune system to fight cancer. By activating T cells with CD28-based antigens, researchers hope to boost the immune system's ability to recognize and attack cancer cells.
T-Box Domain Proteins are a family of transcription factors that play important roles in the development and differentiation of various cell types in the body. They are characterized by the presence of a conserved T-box DNA binding domain, which allows them to interact with specific DNA sequences and regulate gene expression. T-Box Domain Proteins are involved in a wide range of biological processes, including cell proliferation, differentiation, migration, and apoptosis. They have been implicated in the development and progression of various diseases, including cancer, cardiovascular disease, and neurological disorders. In the medical field, T-Box Domain Proteins are the subject of ongoing research, with the goal of understanding their roles in disease pathogenesis and developing targeted therapies for the treatment of these conditions.
Wallerian degeneration is a process that occurs in the nervous system following damage to a nerve or neuron. It is named after the scientist Sir Charles Bell's student, John Charles Waller, who first described it in the 19th century. When a nerve or neuron is damaged, the part of the nerve that is closest to the site of injury begins to break down and die. This is called the axon. The axon is surrounded by a layer of supportive cells called the myelin sheath, which helps to insulate and protect the nerve fibers. As the axon dies, the myelin sheath begins to break down as well. The process of Wallerian degeneration is a natural response to injury, and it helps to prevent the spread of damage to healthy tissue. However, it can also lead to the loss of function in the affected nerve or neuron. This is because the myelin sheath is important for transmitting electrical signals along the nerve fibers, and its breakdown can disrupt this process. Wallerian degeneration can occur in a variety of conditions that affect the nervous system, including traumatic injuries, infections, and certain neurological disorders. It is an important area of study in the field of neuroscience, as it helps researchers to understand the mechanisms of nerve damage and repair.
Nerve tissue proteins are proteins that are found in nerve cells, also known as neurons. These proteins play important roles in the structure and function of neurons, including the transmission of electrical signals along the length of the neuron and the communication between neurons. There are many different types of nerve tissue proteins, each with its own specific function. Some examples of nerve tissue proteins include neurofilaments, which provide structural support for the neuron; microtubules, which help to maintain the shape of the neuron and transport materials within the neuron; and neurofilament light chain, which is involved in the formation of neurofibrillary tangles, which are a hallmark of certain neurodegenerative diseases such as Alzheimer's disease. Nerve tissue proteins are important for the proper functioning of the nervous system and any disruption in their production or function can lead to neurological disorders.
Orchitis is an inflammation of one or both testicles. It is usually caused by a bacterial or viral infection, but can also be caused by other factors such as injury, certain medications, or an allergic reaction. Symptoms of orchitis may include pain or swelling in the affected testicle, fever, chills, and tenderness in the groin area. Orchitis can be a serious condition if left untreated, as it can lead to complications such as infertility or the formation of a testicular cyst or abscess. Treatment typically involves antibiotics or antiviral medication, depending on the cause of the inflammation.
Interleukin-2 receptor beta subunit (IL-2Rβ) is a protein that plays a crucial role in the immune system. It is a component of the interleukin-2 receptor complex, which is found on the surface of immune cells such as T cells, B cells, and natural killer cells. The IL-2Rβ subunit is necessary for the binding of interleukin-2 (IL-2), a cytokine that is produced by activated T cells and plays a key role in the proliferation and differentiation of immune cells. When IL-2 binds to its receptor complex, it triggers a signaling cascade that leads to the activation and proliferation of T cells and other immune cells. In the medical field, the IL-2Rβ subunit is often studied in the context of autoimmune diseases, cancer, and infectious diseases. For example, in some autoimmune diseases, the overproduction of IL-2 and its receptor complex can lead to the activation of immune cells and the destruction of healthy tissues. In cancer, the IL-2Rβ subunit is often overexpressed on tumor cells, making it a potential target for cancer therapies. In infectious diseases, the IL-2Rβ subunit is involved in the immune response to pathogens and can be a target for vaccines and other treatments.
