Anti-N-Methyl-D-Aspartate Receptor Encephalitis: Disorder characterized by symptoms of CATATONIA; HYPOVENTILATION; DYSKINESIAS; ENCEPHALITIS; and SEIZURES followed by a reduced CONSCIOUSNESS. It is often followed by a viral-like prodrome. Many cases are self-limiting and respond well to IMMUNOMODULATORY THERAPIES against the NMDA RECEPTORS antibodies.Receptors, Amino Acid: Cell surface proteins that bind amino acids and trigger changes which influence the behavior of cells. Glutamate receptors are the most common receptors for fast excitatory synaptic transmission in the vertebrate central nervous system, and GAMMA-AMINOBUTYRIC ACID and glycine receptors are the most common receptors for fast inhibition.Encephalitis: Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections (see ENCEPHALITIS, VIRAL) are a relatively frequent cause of this condition.Dyskinesias: Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see MOVEMENT DISORDERS). Dyskinesias are also a relatively common manifestation of BASAL GANGLIA DISEASES.Teratoma: A true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs. It is composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They are classified histologically as mature (benign) or immature (malignant). (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1642)Receptors, N-Methyl-D-Aspartate: A class of ionotropic glutamate receptors characterized by affinity for N-methyl-D-aspartate. NMDA receptors have an allosteric binding site for glycine which must be occupied for the channel to open efficiently and a site within the channel itself to which magnesium ions bind in a voltage-dependent manner. The positive voltage dependence of channel conductance and the high permeability of the conducting channel to calcium ions (as well as to monovalent cations) are important in excitotoxicity and neuronal plasticity.Aspartic Acid: One of the non-essential amino acids commonly occurring in the L-form. It is found in animals and plants, especially in sugar cane and sugar beets. It may be a neurotransmitter.Autoantibodies: Antibodies that react with self-antigens (AUTOANTIGENS) of the organism that produced them.Immunoglobulins, Intravenous: Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.Encephalitis, Viral: Inflammation of brain parenchymal tissue as a result of viral infection. Encephalitis may occur as primary or secondary manifestation of TOGAVIRIDAE INFECTIONS; HERPESVIRIDAE INFECTIONS; ADENOVIRIDAE INFECTIONS; FLAVIVIRIDAE INFECTIONS; BUNYAVIRIDAE INFECTIONS; PICORNAVIRIDAE INFECTIONS; PARAMYXOVIRIDAE INFECTIONS; ORTHOMYXOVIRIDAE INFECTIONS; RETROVIRIDAE INFECTIONS; and ARENAVIRIDAE INFECTIONS.Encephalitis, Japanese: A mosquito-borne encephalitis caused by the Japanese B encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE) occurring throughout Eastern Asia and Australia. The majority of infections occur in children and are subclinical or have features limited to transient fever and gastrointestinal symptoms. Inflammation of the brain, spinal cord, and meninges may occur and lead to transient or permanent neurologic deficits (including a POLIOMYELITIS-like presentation); SEIZURES; COMA; and death. (From Adams et al., Principles of Neurology, 6th ed, p751; Lancet 1998 Apr 11;351(9109):1094-7)Encephalitis Virus, Japanese: A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), which is the etiological agent of Japanese encephalitis found in Asia, southeast Asia, and the Indian subcontinent.Chemotaxis: The movement of cells or organisms toward or away from a substance in response to its concentration gradient.Aspartate Aminotransferases: Enzymes of the transferase class that catalyze the conversion of L-aspartate and 2-ketoglutarate to oxaloacetate and L-glutamate.

It also causes PARATYPHOID FEVER.Chemoreceptor Cells: Cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptor cells may monitor external stimuli, as in TASTE and OLFACTION, or internal stimuli, such as the concentrations of OXYGEN and CARBON DIOXIDE in the blood.Limbic Encephalitis: A paraneoplastic syndrome marked by degeneration of neurons in the LIMBIC SYSTEM. Clinical features include HALLUCINATIONS, loss of EPISODIC MEMORY; ANOSMIA; AGEUSIA; TEMPORAL LOBE EPILEPSY; DEMENTIA; and affective disturbance (depression). Circulating anti-neuronal antibodies (e.g., anti-Hu; anti-Yo; anti-Ri; and anti-Ma2) and small cell lung carcinomas or testicular carcinoma are frequently associated with this syndrome.Encephalitis, Arbovirus: Infections of the brain caused by arthropod-borne viruses (i.e., arboviruses) primarily from the families TOGAVIRIDAE; FLAVIVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; and RHABDOVIRIDAE. Life cycles of these viruses are characterized by ZOONOSES, with birds and lower mammals serving as intermediate hosts. The virus is transmitted to humans by the bite of mosquitoes (CULICIDAE) or TICKS. Clinical manifestations include fever, headache, alterations of mentation, focal neurologic deficits, and COMA. (From Clin Microbiol Rev 1994 Jan;7(1):89-116; Walton, Brain's Diseases of the Nervous System, 10th ed, p321)Encephalitis Virus, Venezuelan Equine: A species of ALPHAVIRUS that is the etiologic agent of encephalomyelitis in humans and equines. It is seen most commonly in parts of Central and South America.Encephalitis, Herpes Simplex: An acute (or rarely chronic) inflammatory process of the brain caused by SIMPLEXVIRUS infections which may be fatal. The majority of infections are caused by human herpesvirus 1 (HERPESVIRUS 1, HUMAN) and less often by human herpesvirus 2 (HERPESVIRUS 2, HUMAN). Clinical manifestations include FEVER; HEADACHE; SEIZURES; HALLUCINATIONS; behavioral alterations; APHASIA; hemiparesis; and COMA. Pathologically, the condition is marked by a hemorrhagic necrosis involving the medial and inferior TEMPORAL LOBE and orbital regions of the FRONTAL LOBE. (From Adams et al., Principles of Neurology, 6th ed, pp751-4)Encephalitis, St. Louis: A viral encephalitis caused by the St. Louis encephalitis virus (ENCEPHALITIS VIRUS, ST. LOUIS), a FLAVIVIRUS. It is transmitted to humans and other vertebrates primarily by mosquitoes of the genus CULEX. The primary animal vectors are wild birds and the disorder is endemic to the midwestern and southeastern United States. Infections may be limited to an influenza-like illness or present as an ASEPTIC MENINGITIS or ENCEPHALITIS. Clinical manifestations of the encephalitic presentation may include SEIZURES, lethargy, MYOCLONUS, focal neurologic signs, COMA, and DEATH. (From Adams et al., Principles of Neurology, 6th ed, p750)Encephalitis Viruses: A collection of single-stranded RNA viruses scattered across the Bunyaviridae, Flaviviridae, and Togaviridae families whose common property is the ability to induce encephalitic conditions in infected hosts.Escherichia coli: A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a well-defined autoimmune disorder. Hashimotos encephalopathy (HE) is a still controversial entity, lacking definite diagnostic criteria. We described a 14-year-old-girl presenting with a clinical picture consistent with the diagnosis of anti-NMDAR encephalitis, confirmed by NMDAR antibody testing. Four years earlier, she had presented a similar episode of acute encephalopathy diagnosed as HE. Anti-NMDAR encephalitis and HE share similar clinical features so that the differential diagnosis can be difficult if specific antibodies are not tested. The correct diagnosis of anti-NMDAR encephalitis is crucial to plan the appropriate management and follow-up, namely in term of oncological screening, since it can be paraneoplastic in origin. We suggest to re-evaluate the clinical history of all subjects with previous HE diagnosis in order to evaluate the possible diagnosis of anti-NMDAR encephalitis and plan the appropriate management of these patients
Author and former New York Post writer, Susanah Cahalan, was diagnosed with anti-NMDA receptor encephalitis. This is an acute inflammation of the brain caused by autoimmunity. This diagnosis may also be considered in a differential diagnosis for HE/SREAT and can share symptoms, such as hallucinations and seizures.

Investigators at Universities of Barcelona, Pennsylvania, Oviedo, and Valencia, and the Spanish NMDAR Encephalitis Work Group report the clinical features of 20 pediatric patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis seen in a single center in Spain in the last 4 years. Median patient age was 13 years (range, 8 months-18 years); 70% were female. Initial symptoms were neurologic (dyskinesias or seizures) in 12 (60%) and psychiatric in 40%. By one month after disease onset, all had involuntary movements and changes in behavior and speech. All patients received steroids, IV immunoglobulin or plasma exchange, and 7 rituximab or cyclophosphamide. At a median follow-up of 17.5 months, 85% had substantially recovered, 10% had moderate or severe deficits, and 1 had died. Three patients had previous episodes compatible with anti-NMDAR encephalitis, and 2 had additional relapses. Ovarian teratoma was identified in 2 patients (10%), 1 at disease onset and the other one-year later. A ...
Cognitive and social functioning deficits after anti-N-methyl-D-aspartate receptor encephalitis: an exploratory case series -...
Background: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a recently described life-threatening autoimmune disorder associated with a characteristic multi-stage neuropsychiatric syndrome. Although it is known that the majority of patients experience neuropsychological disturbance post-treatment, some aspects of the cognitive profile remain unclear. Methods: This study sought to investigate patterns of cognitive functioning in a sample of anti-NMDAR encephalitis patients. Seven (6F:1M; mean age, 26.4 years; range, 16-37 years) treated patients completed a comprehensive set of neurocognitive and social functioning measures. Performance was analyzed using normative data (where available), and comparison with matched controls (10F:4M; mean age, 25.8 years; range, 16-38 years). Results: Individual cognitive profiles ranged from within normal limits to extensive dysfunction. Relative to controls, the patient groups performance was affected in the domains of verbal/ visual memory, working ...
Anti-N-methyl-D-aspartate receptor encephalitis associated with ovarian teratoma: A case report | e-journal.gr
We determined that this patient had definite paraneoplastic encephalitis, with predominant involvement of the limbic system. Accordingly, she developed a gradual loss of short-term memory, seizures, psychiatric symptoms, MRI abnormalities in the limbic system and positive titres for antineuronal antibodies6-8.. Central nervous system tissue in the teratoma might be a trigger of the immune reaction. The majority of teratomas are mature cystic ones. Immature teratomas (constituting 1% of all teratomas) were present in 29% of anti-NMDAR related cases9. Bilateral teratomas were present in 14% of cases, comparable to 12% described in general.. Development of paraneoplastic syndromes in the setting of gynecologic malignancy is rare. When they occur, the neurologic symptoms most often precede and usually lead to the diagnosis of malignancy. Early diagnosis and aggressive treatment of the underlying tumor may stabilize or improve the neurologic abnormalities. Paraneoplastic neurological syndromes (PLE) ...
Link between HLA alleles and anti-NMDAR encephalitis | Journal of Neurology, Neurosurgery & Psychiatry
In their JNNP paper, Shu et al investigated whether anti-NMDAR encephalitis was associated with any HLA alleles, utilising samples from 61 patients with anti-NMDAR encephalitis and 571 healthy controls from the Chinese Han population.4 In this study, six HLA loci (HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA -DQA1 and HLA -DQB1) were typed using a PCR sequence-based typing method, while the German study mentioned above imputed HLA alleles from single nucleotide polymorphisms (SNPs) genotyped on a genome-wide SNP chip array.2 Shu et al demonstrated that the HLA-DRB1*16:02 allele was associated with disease susceptibility (allele frequency: 14.75% in cases vs 4.82% in controls; OR 3.42 (95% CI 1.82 to 6.17)) and the association did not depend on the positivity of tumours. Furthermore, the patients with anti-NMDAR encephalitis with HLA-DRB1*16:02 tended to respond less efficiently to treatment, suggesting that certain genetic backgrounds may contribute to distinct disease development..

A blog post discussing a case report of anti-N-Methyl-D-Aspartate (NMDA) receptor encephalitis associated with autistic regression
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder that was only recently discovered through the identification of the anti-NMDAR autoantibody in 2007. With an increasing amount of new cases of this autoimmune disorder on the rise, it is important for healthcare providers to be aware of its pathophysiology, presentation, course of disease, and treatment modalities for the successful management of patients with anti-NMDAR encephalitis.
Neurological response to early removal of ovarian teratoma in anti-NMDAR encephalitis | Journal of Neurology, Neurosurgery &...
We report an 18-year-old woman with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, who developed psychiatric symptoms, progressive unresponsiveness, dyskinesias, hypoventilation, hypersalivation and seizures. Early removal of an ovarian teratoma followed by plasma exchange and corticosteroids resulted in a prompt neurological response and eventual full recovery. Serial analysis of antibodies to NR1/NR2B heteromers of the NMDAR showed an early decrease of serum titers, although the CSF titers correlated better with clinical outcome. Patient fs antibodies reacted with areas of the tumor that contained NMDAR-expressing tissue. Search for and removal of a teratoma should be promptly considered after the diagnosis of anti-NMDAR encephalitis. ...
Anti-AMPA receptor encephalitis associated with thymomatous myasthenia gravis. - Radcliffe Department of Medicine
No thymomatous myasthenia gravis (TMG) has been reported in patients with anti-α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor encephalitis (AMPAR-E). We described clinical presentation and autoimmune profile of the first case with both AMPAR-E and TMG. Clinical information was obtained from original medical records. Antibodies against AMPAR and confounding antigens were examined on transfected human embryonic kidney 293 cells by the indirect immunofluorescence method. In this case, anti-AMPAR antibodies and anti-acetylcholine receptor (AchR) antibodies were both positive and could explain the encephalitis and MG respectively. This report also indicated the complexity of autoimmunity network associated with thymoma. However, the relationships between thymoma, MG and AMPAR-E remained unclear.
Researchers at Johns Hopkins University published a retrospective study in which they examined the PET scans of patients who had been definitively diagnosed with autoimmune encephalitis over a ten-year period. They compared patients with anti-NMDA receptor encephalitis with other subgroups. They found those with anti-NMDAr AE consistently showed abnormalities in the form of hypometabolism (lower metabolism) in a part of the brain called the occipital lobe. The authors recalled that formerly some of the first published cases of anti-NMDAr AE included reports of PET scan abnormalities that included occipital hypometabolism, along with other notable observations.. However they mentioned there has been some uncertainty of the specificity and practicality of using PET in autoimmune encephalitis, as there can be wide variations found in patients in the same subgroup (including anti-NMDA). In addition, all hospitals do not utilize PET scans in the diagnostic workup for AE. Despite these challenges, ...

The book narrates Cahalans issues with anti-NMDA receptor encephalitis and the process by which she was diagnosed with this form of encephalitis. She wakes up in a hospital with no memory of the events of the previous month, during which time she would have violent episodes and delusions. Her eventual diagnosis is made more difficult by various physicians misdiagnosing her with several theories such as "partying too much" and schizoaffective disorder. Eventually several physicians, including Dr. Souhel Najjar, began to suspect that Cahalan was suffering from an autoimmune disease. Najjar diagnosed Cahalan using a test that involved her drawing a clock, a test normally given to people suspected of having dementia or Alzheimers disease. Rather than drawing the clock face normally, the disease caused Cahalan to draw all of the numbers 1 through 12 on the right face of the clock, because the right side of her brain, which regulates the left side of the body, was inflamed. Najjar used this ...
Organic Anion Transporting Polypeptide - Cenicriviroc, a Novel CCR5 (R5) and CCR2 Antagonist blocks HIV entry
Steiner (9) tested serum from 459 sufferers with either schizophrenia or other psychiatric disorders for the presence of NMDAR autoimmunity. They found two individuals with GluN1 IgG antibodies, but both experienced classic anti-NMDAR encephalitis with neurologic features, and their conditions had been misdiagnosed. Additional immunoglobulin subtypes were recognized in 10% of individuals with schizophrenia in the initial statement (IgA or IgM antibodies, or both, reacting with GluN1/GluN2 NMDAR subunits). However, subsequent work found that the rate of recurrence of IgA and IgM antibodies realizing NMDARs is similar in control and healthy individuals (10), again casting doubt over the scientific Afatinib relevance of the NMDAR antibody subtypesa bottom line consistent with function by Hammer (5), also displaying ~10% serum positivity of IgM and IgA NMDAR antibodies in sufferers and control topics. Pathmanandavel (1) tested for Afatinib the current presence of NMDAR autoantibodies within a people ...
Every disease needs a patient advocate, and NMDA receptor encephalitis has found its spokesperson in Susannah Cahalan. For several years prior to and during the onset of her illness, Cahalan worked as a journalist at the New York Post, and she tackles the book with the intensity, readability, and bluntness expected of a Post journalist. Here, she finds the balance between being biographical and educational without becoming laden with facts or burdened by irrelevant detail - it is an engaging read.. In Brain on Fire, Cahalan describes her battle with NMDA receptor encephalitis, a condition first well described by neurologist Josep Dalmau, MD, PhD, and colleagues in 2007. The condition, which is is still not widely and commonly recognized, even among physicians, is an acute autoimmune encephalitis caused by immune-mediated attack against NR1- and NR2-subunits of the glutamate NMDA receptor. NMDA encephalitis is often associated with ovarian teratoma when diagnosed in young women, though it can ...

Abstract Since its discovery in 2007, the encephalitis associated with antibodies against the N-methyl-D-aspartate receptor (NMDAR) has entered the mainstream of neurology and othe..
Anti-N-methyl-D-aspartate receptor (anti-NMDA-R) encephalitis is an immune-mediated syndrome that remains under-recognized despite a growing body of literature. This syndrome has been predominantly described in young females with a constellation of symptoms, including personality changes, autonomic dysfunction and neurologic decompensation. It is commonly associated with mature ovarian teratomas. We describe the classic presentation of anti-NMDA-R encephalitis in three dramatically different patients: Case A, a young woman with ovarian teratoma; Case B, the eldest case reported to date; and Case C, a young male with no identifiable tumor. We review the literature summarizing the differential diagnosis, investigative approach, treatment options and challenges inherent to this disorder. We advocate good supportive care, involvement of multiple health disciplines and use of immune-modulating therapies in patient management. These cases underscore the need for increased awareness and high diagnostic ...

First-line immunotherapy was often insufficient to control the disease; in the group of patients in the cited study, the addition of second-line immunotherapy was associated with a better outcome compared with those not receiving second-line immunotherapy.4 Immunotherapy and tumor removal, if applicable, result in substantial neurological improvement in 81% of patients with anti-NMDAR encephalitis after a median follow-up of 24 months. Moreover, second-line immunotherapy with rituximab, cyclophosphamide, or both, improved the outcome of patients who did not respond to first-line treatment and decreased the occurrence of relapses.4 However, 25% of patients suffer from severe neurological deficits or die. Upon recovery, amnesia is evident for the duration of the illness, and there is a risk of relapse of the encephalitic syndrome.6,7 The gradual process of clinical recovery may take a long time (sometimes years) but can, in some patients, even be associated with improvement of frontotemporal brain ...

BACKGROUND: Paraneoplastic neurological syndromes (PNNS) are remote effects of a tumor and mediated by an altered immune reaction. In the last ten years, the spectrum of PNNS has changed profoundly with the discovery of a new category of neurological diseases that are associated with antibodies against surface or synaptic antigens. In contrast to classical PNNS, patients with surface receptor autoimmunity are often highly responsive to immunotherapy. OBJECTIVES: This article provides an update on the most relevant PNNS, focusing on specific syndromes associated with antibodies against classical onconeuronal antigens as well as surface and synaptic proteins ...
Howard Forman (HF): In Brain on Fire, your debut book that has been called by NPR "stunningly brave" and a "gift of a book from one of Americas most courageous young journalists," you write about some harrowing experiences that occurred during 2009, when you were 24 years old. Can you describe some of the symptoms that you experienced during that time?. Susannah Cahalan (SC): The earliest symptoms were subtle. At first, I just felt "off." I was tired and emotional. I became fixated on certain things: I believed I had bedbugs to the point that I urged an exterminator to debug my apartment even when he insisted I didnt have an infestation. I thought my boyfriend was cheating on me and went in search of nonexistent clues of his philandering.. Then, I felt numbness on the left side of my body, which my neurologist ascribed to "mono." But I didnt link my odd feelings with this physical experience.. Later, my behavior became increasingly irrational. My moods fluctuated from extreme happiness to ...
FDG-PET hyperactivity in basal ganglia correlating with clinical course in anti-NDMA-R antibodies encephalitis | Journal of...
A form of encephalitis associated with anti-N-methyl-d-aspartate receptor (anti-NMDA-R) antibodies has recently been described.1 Reported patients are mainly young women, presenting with severe encephalitis and additional distinctive neurological features. Around 60% have an ovarian teratoma.1 The severe course of the disease does not rule out favourable prognosis. Immunotherapy is advocated1-3 and appears to be associated with improved outcome.. We present a patient with anti-NMDA-R encephalitis and serial [18F]-fluorodeoxyglucose-positron emission tomography (FDG-PET) examinations showing markedly increased activity in the basal ganglia as compared with that in the cortex when extrapyramidal features were prominent, which normalised after improvement of this movement disorder. ...
OBJECTIVE: We tested whether antibody screening samples of patients with suspected autoimmune encephalitis with additional research assays would improve the detection of autoimmune encephalitis compared with standard clinical testing alone. METHODS: We examined 731 samples (333 CSF, 182 sera, and 108 pairs) from a cohort of 623 patients who were tested for CNS autoantibodies by the University of Pennsylvania clinical laboratory over a 24-month period with cell-based assays (CBAs) on commercially obtained slides of fixed cells for antibodies to NMDA receptor (NMDAR), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR), γ-aminobutyric acid-B receptor (GABABR), leucine-rich glioma-inactivated 1 (LGI1), contactin-associated protein-like 2 (Caspr2), and glutamic acid decarboxylase (GAD65 ...
N-methyl-D-aspartate receptor antibodies in pediatric dyskinetic encephalitis lethargica. - Nuffield Department of Clinical...
Encephalitis lethargica (EL) describes an encephalitis with psychiatric, sleep, and extrapyramidal movement disorders. Dyskinetic and parkinsonian forms have been described. EL shares clinical features with the anti-N-methyl-D-aspartate receptor (NMDAR-Ab) encephalitis. We studied 20 sera from pediatric patients with contemporary EL. Ten sera (from 2 males and 8 females, aged 1.3-13 years) and 6/6 cerebrospinal fluid samples were positive for NMDAR-Ab. NMDAR-Ab-positive patients had dyskinesias, agitation, seizures, and insomnia, whereas parkinsonism and somnolence dominated in the NMDAR-Ab-negative children. We were unable to identify any tumors. The dyskinetic form of EL is an NMDAR-Ab encephalitis and can affect very young children.

Mapping autoantigen epitopes: molecular insights into autoantibody-associated disorders of the nervous system | Journal of...
Autoantibodies targeting extracellular, rather than intracellular, domains of an antigen have a higher probability of being pathogenic by modulating receptor function, which can be studied in vitro and in vivo. However, since epitopes may vary between species, matching epitope targets between human autoantibodies and murine models is important for animal studies. For instance, the majority of patients with anti-MOG antibodies did not recognize conformational intact mMOG , whereas epitopes recognized by anti-NMDAR antibodies are similar between the two species , or at least share some cross-reactivity as in the case of anti-AQP4 antibodies [62, 134]. Longitudinal studies of autoimmune neurological disorders in humans are necessary to substantiate findings from animal models and determine whether the same mechanisms are relevant to human disease. Based on these results, decisions can be made as to whether the therapies that have proved effective in animal models are translatable to human ...
Stem cells of these tumors formed nests consisting of undifferentiated embryonic cells in the center with more differentiated cells towards the periphery. A type viral particles were seen in the cisternae of rough endoplasmic reticulum. Ultrastructurally the stem cells of ovarian teratomas did not differ from stem cells of testicular or embryo-derived teratomas. They were however distinct from the cleavage stage embryonic cells and/or the unfertilized ovum, they stemmed from. They correspond both cytologically and developmentally to ectodermal embryonic cells from the egg-cylinder, the most advanced developmental stage of parthenotes observed previously in the ovary of LT mice.

Progressive encephalomyelitis with rigidity and myoclonus: glycine and NMDA receptor antibodies. - Oxford Neuroscience
BACKGROUND: The syndrome of progressive encephalopathy with limb rigidity has been historically termed progressive encephalomyelitis with rigidity and myoclonus (PERM) or stiff-person syndrome plus. METHODS: The case is presented of a previously healthy 28-year-old man with a rapidly fatal form of PERM developing over 2 months. RESULTS: Serum antibodies to both NMDA receptors (NMDAR) and glycine receptors (GlyR) were detected postmortem, and examination of the brain confirmed an autoimmune encephalomyelitis, with particular involvement of hippocampal pyramidal and cerebellar Purkinje cells and relative sparing of the neocortex. No evidence for an underlying systemic neoplasm was found. CONCLUSION: This case displayed not only the clinical features of PERM, previously associated with GlyR antibodies, but also some of the features associated with NMDAR antibodies. This unusual combination of antibodies may be responsible for the particularly progressive course and sudden death.

There are multiple etiologies that could potentially cause the sub-acute neurological decline in "Rapidly-Progressive Dementias." First, there are complications of medical conditions that can cause a subacute decline, including metabolic, infectious, inflammatory, neoplastic or vascular conditions. Each of these disease categories have specific treatment strategies that are important to identify early in the disease course. Examples of medical conditions that could cause a rapid decline in cognition include thyroid abnormalities, auto-immune diseases (i.e. the bodys immune system attacking itself as in systemic lupus erythematosis), infections of the nervous system (i.e.meningitis), and cardiac or pulmonary insufficiency. Second, there are conditions that specifically target the central nervous system. Examples include the neurodegenerative condition subacute spongiform encephalopathy, or Creutzfeldt-Jakob disease, auto-immune diseases of the central nervous system (i.e. anti-NMDA ...
The Rokitansky nodule or dermoid plug of ovarian teratomas is a frequent site of malignant transformation and imaging findings suggestive of malignant transformation have been proposed. Transmural growth of the Rokitansky nodule should raise concern for malignant transformation. Softer signs of malignant transformation include contrast enhancement of the Rokitansky nodule and an obtuse angle between the nodule and the inner wall of the cyst ...

- Recently, several studies have reported human leucocyte antigen (HLA) associations with antibody-mediated encephalitis, including anti-NMDAR encephalitis and anti-leucine-rich glioma-inactivated1 (LGI1) encephalitis. (bmj.com)
- only a borderline association with HLA-B*07:02 in German patients with anti-NMDAR encephalitis has been reported. (bmj.com)
- In their JNNP paper, Shu et al investigated whether anti-NMDAR encephalitis was associated with any HLA alleles, utilising samples from 61 patients with anti-NMDAR encephalitis and 571 healthy controls from the Chinese Han population. (bmj.com)
- Furthermore, the patients with anti-NMDAR encephalitis with HLA-DRB1*16:02 tended to respond less efficiently to treatment, suggesting that certain genetic backgrounds may contribute to distinct disease development. (bmj.com)
- Although replication studies are required in other cohorts from multiple populations to assess whether the findings are commonly shared across populations or are unique to specific populations, this study highlights the possible link between HLA alleles and anti-NMDAR encephalitis and paves the way for further discussions on how and what kinds of T cells contribute to the disease pathogenesis.
