Pathogenic bacteria produce numerous virulence factors, including protein toxins, to enhance their growth and survival within the host. Our lab seeks to understand the mechanisms of bacterial toxin delivery to identify and exploit therapeutic targets. In this project, we have focused on a member of the repeats-in-toxin (RTX) family of proteins, which are secreted by many Gram negative bacteria, including Bordetella pertussis, Escherichia coli, and Aggregatibacter actinomycetemcomitans. The leukotoxin (LtxA) secreted by A. actinomycetemcomitans specifically kills human white blood cells to disrupt the host immune response and therefore plays a key role in bacterial colonization of the host. The cell type specificity of LtxA arises from its reported targeting of the lymphocyte function-associated antigen-1 (LFA-1) integrin, which is only expressed by human white blood cells. In addition, we recently showed that LtxA binds with a strong affinity to cholesterol, and inhibition of this binding to ...
Background Huntingtons disease (HD) is caused by expanded CAG repeats encoding a polyglutamine tract in the huntingtin (HTT) protein. A number of differentially-expressed protein molecules have been identified in striatum of HD animal models. Here we examined if the expression changes could be visualized in the peripheral leukocytes of HD patients and pre-symptomatic HD (PreHD) carriers. Methods and findings The expression levels of 17 candidate genes that differentially expressed in striatum between transgenic HD and wild-type mice in literature were measured in the peripheral leukocytes of 4 PreHD carriers, 16 HD patients and 20 healthy controls. Four genes majorly involved in metabolism and oxidative stress response, including AHCY1, ACO2, OXCT1 and CAP1, demonstrated consistent downregulation in peripheral leukocytes of both PreHD carriers and HD patients, while UCP2 was only down-regulated in HD patients. Conclusion These results provide potential peripheral biomarkers to indicate disease
Cardiovascular events are the leading cause of death in developed countries worldwide, including Taiwan. Type 2 diabetes mellitus (T2DM), previously considered merely as one of the risk factors, has been recently unanimously accepted to be coronary artery disease-equivalent. How T2DM may lead to accelerated atherosclerosis remains obscure.. Hyperglycemia with or without hyperinsulinemia may lead to higher oxidative stress and generalized inflammation. The oxidative stress and inflammation may play a significant role in the pathogenesis in diabetic complications, including micro- and macro-vascular complications. Macrophages together with T-lymphocytes are the earliest cell-types found in fatty-streaks, the earliest atherosclerotic lesions. Macrophages are also well known cellular mediators of oxidative stress and inflammation. Therefore, it is plausible to hypothesize that macrophages play a crucial role in the pathogenesis of atherosclerosis in patients with T2DM. In addition, the other cell ...
Neutrophils represent the most abundant type of granulocytes, accounting for 25-75% of all circulating human white blood cells (PMID: 23435331, 22491176). Their mechanisms of action encompass degranulation of antimicrobial proteins, release of chemotactic factors (PMID: 22392929, 20140197, 25512469, 21555529), and formation of neutrophil extracellular traps or NETs (PMID: 23435331, 22491176, 15001782) in response to pathogens. Typical markers are CD15, CD66b, CD16, and the absence of CD49d.. Representing 1-10% of peripheral leukocytes, eosinophils in resting state reside mainly in the periphery, especially in lamina propria (PMID: 11877470, 25049430). They readily release their granule content including eosinophil cationic protein (ECP), eosinophil peroxidase (EPX), and major basic protein (MBP) as well as chemokines, and cytokines in response to pathogens (PMID: 25003763). They play a role in antigen presentation and T cell polarization (PMID: 25003763, 8450230, 20065995, 16551246). A specific ...
Apoptosis. Coloured scanning electron micrograph of human white blood cells (leucocytes), showing one cell undergoing apoptosis. Apoptosis is the process of genetically programmed cell death. At centre, an apoptotic white blood cell has shrunk and its cytoplasm has developed blebs (grape-like clusters). Normal white blood cells are seen beside it. These white blood cells are myeloid leucocytes, originating from bone marrow. The human myeloid cell line depends on growth factors to survive, and cells undergo apoptosis when deprived of growth factors. Research on apoptosis may provide genetic treatments for diseases such as cancer. Magnification: x1,500 at 6x7cm size. - Stock Image P248/0134
Non-healing wounds pose a major burden to patients and health care systems alike. These wounds are chronically stuck in the inflammatory phase of the healing process without transitioning to the proliferative phase. They are also characterized by the excessive presence of leukocytes which are assumed to provoke the persistent inflammation observed in pathological wound healing. Recent studies suggested a beneficial role of cold physical plasma in the treatment of chronic wounds. Hence, it was the central question, whether exposure to cold physical plasma would affect the viability and/or function of human leukocytes. Cold plasma displays various properties of which the generation of reactive molecules, such as reactive oxygen and nitrogen species (ROS/RNS), where found to be central in mediating redox changes in leukocytes. Oxidative stress was present especially in lymphocytes that readily underwent apoptosis after exposure to plasma. This was largely a direct consequence of plasma-generated hydrogen
Flow-FISH (fluorescent in-situ hybridization) is a cytogenetic technique to quantify the copy number of specific repetitive elements in genomic DNA of whole cell populations via the combination of flow cytometry with cytogenetic fluorescent in situ hybridization staining protocols. Flow-FISH is most commonly used to quantify the length of telomeres, which are stretches of repetitious DNA (hexameric TTAGGG repeats) at the distal ends of chromosomes in human white blood cells, and a semi-automated method for doing so was published in Nature Protocols. Telomere length in white blood cells has been a subject of interest because telomere length in these cell types (and also of other somatic tissues) declines gradually over the human lifespan, resulting in cell senescence, apoptosis, or transformation. This decline has been shown to be a surrogate marker for the concomitant decline in the telomere length of the hematopoietic stem cell pool, with the granulocyte lineage giving the best indication, ...
Positive evolutionary pressure has apparently preserved the ability to synthesize chemically authentic morphine, albeit in homeopathic concentrations, throughout animal phyla. ... The apparently serendipitous finding of an opiate alkaloid-sensitive, opioid peptide-insensitive, µ3 opiate receptor subtype expressed by invertebrate immunocytes, human blood monocytes, macrophage cell lines, and human blood granulocytes provided compelling validating evidence for an autonomous role of endogenous morphine as a biologically important cellular signalling molecule (Stefano et al., 1993; Cruciani et al., 1994; Stefano and Scharrer, 1994; Makman et al., 1995). ...

The purpose of this study is to investigate whether low-intensity current affects cells in culture. Two types of human cells: white blood cells (lymphocytes) and leukemia cells (molt-4 cells), were studied. A low-intensity time-varying electric current (0.14 milliamp) generated by the Clark Zapper was applied to cell cultures via two platinum electrodes for 2 hrs at 37o C. Cell counts were made at different times after electric current application. Results show that the current had no significant effect on human white blood cells up to 24 hrs after exposure, whereas it significantly inhibited the growth of leukemia cells. At 24 hrs after exposure, concentration of leukemia cells exposed to the electric current was only 58% of that of non-exposed leukemia cells.. This data suggests that the electric current can selectively inhibit the growth of leukemia cells and does not significantly affect normal cells. A manuscript describing these results is in preparation for publication. Further research ...

For expression profiling to have a practical impact in the management of immune-related disease it is essential that it can be applied to peripheral blood cells. Early studies have used total peripheral blood mononuclear cells, and as a consequence the majority of the disease-related signatures identified have simply reflected differences in the relative abundance of individual cell types between patients and controls. To identify cell-specific changes in transcription it would be necessary to profile purified leucocyte subsets. We have used sequential rounds of positive selection to isolate CD4 and CD8 T cells, CD19 B cells, CD14 monocytes and CD16 neutrophils for microarray analysis from a single blood sample. We compared gene expression in cells isolated in parallel using either positive or negative selection and demonstrate that there are no significant consistent changes due to positive selection, and that the far inferior results obtained by negative selection are largely due to reduced purity.

In the past several years, scanning electron microscopy has become one of the popular methods in biology research. Two main technical advancements-improvement of specimen preparation and the improvement of the instrument-are responsible for the massive amount of data that has been generated in a relatively short time and have greatly widened our knowledge concerning a variety of surface features. However, scanning electron microscopic studies of the lymphocyte surface have provided the most excitement as well as generated many controversies. This book presents the current knowledge in this field and is a useful reference, especially for the beginners in this field. ...

With this study, we have demonstrated that we can distinguish between individuals exposed and unexposed to tobacco smoke on the basis of mRNA expression in peripheral leukocytes. Furthermore, we have shown that active exposure to tobacco smoke is associated with a biologically relevant mRNA expression signature. Previously, several studies have shown that, experimentally, in vitro and in animals, single exposures [e.g., heat shock (6) and 17β-estradiol (7)] alter gene expression in peripheral leukocytes. Our study shows that the use of expression patterns can be expanded to identify a complex exposure in human observational studies.. In this study, we examined gene expression in total leukocytes, rather than specific cellular subsets. Total numbers of peripheral leukocytes characteristically have been shown to differ by smoking status (8, 9), and differential counts have been reported to differ by number of cigarettes smoked (8) or to remain unchanged (10). Recently, interindividual variation ...
The lymphatic system includes specialised organs and tissues where leukocytes develop. During an immune response to pathogens, we may become aware of swollen lymph nodes (popularly called glands) in the neck, armpits or groin, which enlarge when the leukocytes they contain are multiplying near a site of infection. Leukocytes can distinguish between self, the cells and proteins generated by the organism whose body they patrol, and non-self (or foreign) material such as pathogens that originated outside the hosts body. Leukocytes are self-tolerant, i.e. they do not normally attack the hosts own cells or body proteins, but direct their actions only against non-self material that may pose a threat.. Although we have referred to the immune response, as if it was just one thing, in fact, there are two types of immune response, distinguished as innate and adaptive immunity.. ...

Immune cell therapy is considered one of the most promising anti-cancer strategy in many human cancers. Compared to the destructive methods such as surgery, radiation, and chemotherapy, anti-cancer immune therapy is safer and less toxic method in the treatment of human cancer patients.. Among the immune cell therapy, autologous adoptive immune cell therapy is a method to transfer the immune cells derived from peripheral white blood cells and expanded and stimulated with various cytokines and tumor specific antigens in cancer patients. Recent development of the technique to expand immune cells ex vivo make autologous adoptive immune cell therapy much more feasible and popular. However, immune cell therapy showed response of below 10% currently in several clinical trials. The reason of poor response is that the adopted immune cells have to overcome the highly immune compromised environment in advanced or recurrent cancer patients.. The low-dose radiation, defined as the radiation below the ...

Immune function is generally reported to be impaired in uncontrolled diabetes mellitus. We have previously reported that very-low-density lipoproteins (VLDL) from diabetic rat serum injure endothelial cells in vitro. Thus, we wanted to determine if VLDL would also injure lymphocytes and impair the immunity of the streptozotocin-induced diabetic rat. The immunologie functions of spleen cells from normal and diabetic rats were studied using the in vitro mitogenic stimulation assay and mixed lymphocyte responses (MLR). The effects of diabetic serum and VLDL isolated from diabetic rat serum on normal spleen cells were also determined. Both the absolute peripheral blood leukocyte (PBL) and spleen cell numbers of diabetic rats were significantly decreased from those of normal rats (P , 0.02). In PBL there was a decreased percentage of lymphocytes and increased percentage of neutrophils (both P , 0.02). The mitogenic stimulation responses of spleen cells from diabetic rats were consistently lower than ...
Leukocytes play an important role in the human immune system. The family of leukocytes is comprised of lymphocytes, monocytes, eosinophils, basophils, and neutrophils. Any infection or acute stress may increase or decrease the number of leukocytes. An increased percentage of neutrophils may be caused by an acute infection, while an increased percentage of lymphocytes can be caused by a chronic bacterial infection. It is important to realize an abnormal variation in the leukocytes. The five types of leukocytes can be distinguished by their cytoplasmic granules, staining properties of the granules, size of cell, the proportion of the nuclear to the cytoplasmic material, and the type of nucleolar lobes. The number of lobes increased when leukemia, chronic nephritis, liver disease, cancer, sepsis, and vitamin B12 or folate deficiency occurred. Clinical neutrophil hypersegmentation has been widely used as an indicator of B12 or folate deficiency.Biomedical technologists can currently recognize abnormal

Leukocytes, which mount antitumor immune responses, present a barrier and selective pressure in tumor progression (19). Innate immune responses do not rely on antigens for activation, represent the first-line of defense against pathogens and cancer, and are responsible for activating adaptive immunity. In normal breast, CD45+ leukocytes are relatively rare, but detectable in both stroma and within mammary ducts (20). In DCIS, leukocytes are abundant in the stroma surrounding the ducts (especially in high-grade and HER2+ lesions), but intraepithelial leukocytes are rarely detectable (21). Leukocytes also localize to sites of myoepithelial cell layer disruption/microinvasion (21). This limited interaction between leukocytes and cancer cells in DCIS may underlie a mechanism by which tumors evade immune surveillance. Therefore, in DCIS, tumors could still exist in the equilibrium phase, with immune escape likely occurring during or just prior to invasive transition (Fig. 1A).. Both, myeloid and ...

Several mechanisms are associated with brain dysfunction during sepsis; one of the most important are activation of microglia and astrocytes. Activation of glial cells induces changes in permeability of the blood-brain barrier, secretion of inflammatory cytokines, and these alterations could induce neuronal dysfunction. Furthermore, blood-borne leukocytes can also reach the brain and participate in inflammatory response. Mechanisms involved in sepsis-associated brain dysfunction were revised here, focusing in neuroinflammation and involvement of blood-borne leukocytes and glial cells in this process.

We demonstrate an additional step and a positive feedback loop in leukocyte accumulation on inflamed endothelium. Leukocytes in shear flow bind to adherent leukocytes through L-selectin/ligand interactions and subsequently bind downstream and roll on inflamed endothelium, purified E-selectin, P-selectin, L-selectin, VCAM-1, or peripheral node addressin. Thus adherent leukocytes nucleate formation of strings of rolling cells and synergistically enhance leukocyte accumulation. Neutrophils, monocytes, and activated T cell lines, but not peripheral blood T lymphocytes, tether to each other through L-selectin. L-selectin is not involved in direct binding to either E- or P-selectin and is not a major counterreceptor of endothelial selectins. Leukocyte-leukocyte tethers are more tolerant to high shear than direct tethers to endothelial selectins and, like other L-selectin-mediated interactions, require a shear threshold. Synergism between leukocyte-leukocyte and leukocyte-endothelial interactions ...
Analysis of the effect of cyclophosphamide on peripheral blood leukocyte gene expression. Certain chemotherapeutic drugs such as cyclophosphamide can enhance the antitumor efficacy of immunotherapy because of their capacity to modulate innate and adaptive immunity. Indeed, it has been argued that this capacity may be more significant to chemotherapeutic efficacy in general than is presently appreciated. To gain insights into the core mechanisms of chemoimmunotherapy, we methodically profiled the effects of cyclophosphamide on gene expression in bone marrow, spleen and peripheral blood, and on cytokine expression in plasma and bone marrow of tumor-bearing mice. Gene and protein expression were modulated early and transiently by cyclophosphamide, leading to upregulation of a variety of immunomodulatory factors, including danger signals, pattern recognition receptors, inflammatory mediators, growth factors, cytokines, chemokines and chemokine receptors. These factors are involved in sensing
Interaction of leukocytes in flow with adherent leukocytes may contribute to their accumulation at sites of inflammation. Using L-selectin immobilized in a flow chamber, a model system that mimics presentation of L-selectin by adherent leukocytes, we characterize ligands for L-selectin on leukocytes and show that they mediate tethering and rolling in shear flow. We demonstrate the presence of L-selectin ligands on granulocytes, monocytes, and myeloid and lymphoid cell lines, and not on peripheral blood T lymphocytes. These ligands are calcium dependent, sensitive to protease and neuraminidase, and structurally distinct from previously described ligands for L-selectin on high endothelial venules (HEV). Differential sensitivity to O-sialo-glycoprotease provides evidence for ligand activity on both mucin-like and nonmucin-like structures. Transfection with fucosyltransferase induces expression of functional L-selectin ligands on both a lymphoid cell line and a nonhematopoietic cell line. L-selectin ...
Glutathione S-transferase activity was identified in cytosol from human lymphoid-cell lines and peripheral leucocytes (polymorphonuclear-leucocyte/monocyte and small-lymphocyte fractions) and compared with human liver enzyme. The findings of closely similar elution volume in gel filtration, substrate (1-chloro-2,4-dinitrobenzene) and inhibitory (probenecid) kinetics indicate that the liver, leucocyte and lymphoid-cell transferases are closely related. The interaction of reduced glutathione and 1-chloro-2,4-dinitrobenzene was shown to occur in intact-lymphoid-cell culture, to be linear with time and quantity of cells and to have kinetics similar to those of the enzyme reaction catalysed by cytosol. ...
Apoptosis or programmed cell death plays a critical role in both inflammatory and immune responses. Recent evidence demonstrates that control of leukocyte apoptosis is one of the most striking immune system-related roles of melatonin. For this reason, this study evaluated the protective effects of melatonin on human leukocyte apoptosis induced by sustained cytosolic calcium increases. Such protective effects are likely mediated by melatonins free-radical scavenging actions. Treatments with the specific inhibitor of cytosolic calcium re-uptake, thapsigargin (TG), and/or the calcium-mobilizing agonist, N-formyl-methionyl-leucyl-phenylalanine (FMLP), induced intracellular reactive oxygen species (ROS) production, caspase activation as well as DNA fragmentation in human leukocytes. Also, TG- and/or FMLP-induced apoptosis was dependent on both cytosolic calcium increases and calcium uptake into mitochondria, because when cells were preincubated with the cytosolic calcium chelator, dimethyl BAPTA, and the
Background: Bulky DNA adducts are markers of exposure to genotoxic aromatic compounds, which reflect the ability of an individual to metabolically activate carcinogens and to repair DNA damage. Polycyclic aromatic hydrocarbons (PAHs) represent a major class of carcinogens that are capable of forming such adducts. Factors that have been reported to be related to DNA adduct levels include smoking, diet, body mass index (BMI), genetic polymorphisms, the season of collection of biologic material, and air pollutants.. Methods: We pooled 11 studies (3,600 subjects) in which bulky DNA adducts were measured in human white blood cells with similar 32P-postlabeling techniques and for which a similar set of variables was available, including individual data on age, gender, ethnicity, batch, smoking habits, BMI, and season of blood collection, and a limited set of gene variants.. Results: Lowest DNA adduct levels (P = 0.006) were observed in the spring (median = 0.50 adducts per 108 nucleotides), followed ...
In the present condition of the technique of cultivation of tissues, the only possible way of studying leucocytic secretions was to grow colonies of leucocytes in a medium of known properties and to examine the modifications of these properties under the influence of the living cells. The method was far from perfect, because the secretions were mixed with serum and accumulated for 48 hours in a medium where they probably underwent partial destruction. But an approximate idea of certain of the qualities of the secretions, although not of their quantity, could be derived from the experiments. In the fluids extracted from the cultures, we attempted to detect the presence of the leucocytic secretions through their physiological effects on homologous and foreign cells. Two kinds of substances were sought, those which act on homologous cells, and those which destroy foreign erythrocytes.. The secretion by leucocytes of substances necessary to the nutrition of other cells was considered as probable ...
By a News Reporter-Staff News Editor at VerticalNews Science -- DURHAM, N.C. - Physicians and patients who are wary of addiction to pain medication and opioids may soon have a healthier and more natural alternative. A Duke University study revealed that a derivative of DHA (docosahexaenoic acid), a main ingredient of over-the-counter fish oil supplements, can sooth and prevent neuropathic pain caused by injuries to the sensory system. The results appear online in the Annals of Neurology. The research focused on a compound called neuroprotectin D1=protectin D1 (NPD1=PD1), a bioactive lipid produced by cells in response to external stimuli. NPD1=PD1 is present in human white blood cells, and was first identified based on its ability to resolve abdominal and brain inflammation. These compounds are derived from omega-3 fatty acids found in fish oil, but are 1,000 times more potent than their precursors in reducing inflammation, said Ru-Rong Ji, professor of anesthesiology and neurobiology at Duke ...
TY - JOUR. T1 - Leukocyte differentiation antigens in canine cutaneous and oral plasmacytomas. AU - Schrenzel, Mark D.. AU - Naydan, Diane K.. AU - Moore, Peter F. PY - 1998/3. Y1 - 1998/3. N2 - Seventeen cutaneous and oral tumours with light microscopic features of plasmacytomas from 16 dogs were studied. Clinically, most neoplasms were benign, although three recurred after excision and three were locally invasive. Tumours most often arose on the pinnae, digits, gingiva, and inguinal regions near areas of chronic inflammation and exhibited variable degrees of plasmacytic differentiation microscopically. Diagnosis of plasmacytoma was confirmed in paraffin-embedded tissues with a panel of leukocyte differentiation antigen markers that included cross-reactive antibodies for Mb-1 (CD79a), CD3, and vimentin and canine-specific antibodies for CD45RA and CD18. Immunoreactivity for Mb-1 and CD45RA, including staining of multinucleate cells and cells with karyomegaly, confirmed a B-cell origin of ...
The blood delivers leukocytes to the various tissues from the bone marrow, where they are produced. Normal blood leukocyte counts are 4.3-10.8 × 109/L, with neutrophils representing 45-74% of the cells, bands 0-4%, lymphocytes 16-45%, monocytes 4-10%, eosinophils 0-7%, and basophils 0-2%. Variation among individuals and among different ethnic groups can be substantial, with lower leukocyte numbers for certain African-American ethnic groups. The various leukocytes are derived from a common stem cell in the bone marrow. Three-fourths of the nucleated cells of bone marrow are committed to the production of leukocytes. Leukocyte maturation in the marrow is under the regulatory control of a number of different factors, known as colony-stimulating factors (CSFs) and interleukins (ILs). Because an alteration in the number and type of leukocytes is often associated with disease processes, total white blood cell (WBC) count (cells per μL) and differential counts are informative.

In the 9 years since the last review on leukocyte and endothelial interactions was published in this journal many of the critical structures involved in leukocyte adherence to and migration across endothelium have been elucidated. With the advent of cell and molecular biology approaches, investigations have progressed from the early descriptions by intravital microscopy and histology, to functional and immunologic characterization of adhesion molecules, and now to the development of genetically deficient animals and the first phase I trial of anti-adhesion therapy in humans. The molecular cloning and definition of the adhesive functions of the leukocyte integrins, endothelial members of the Ig gene superfamily, and the selectins has already provided sufficient information to construct an operative paradigm of the molecular basis of leukocyte emigration. The regulation of these adhesion molecules by chemoattractants, cytokines, or chemokines, and the interrelationships of adhesion pathways need ...
NK cells have therapeutic potential for a wide variety of human malignancies. However, because NK cells expand poorly in vitro, have limited life spans in vivo, and represent a small fraction of peripheral white blood cells, obtaining sufficient cell numbers is the major obstacle for NK-cell immunot …
Ending your shower in cold water improves circulation. It helps bring the blood back from the surface of the skin to all the internal organs. This process supports the prevention of cardiovascular disease by decreasing inflammation. Cold water contrast also stimulates metabolism, increasing oxygen absorption and carbon dioxide excretion. Carbon dioxide can actually be very toxic to the body when we dont get rid of it efficiently. (This is why deep breathing is so important.) It also increases nitrogen absorption and excretion, increases tissue tone, peripheral white blood cell and red blood cell counts, and decreases blood glucose. In other words, this routine will support many different functions of digestive and cardiovascular health as well as immunity ...

PECAM-1 is a well-studied cellular adhesion and signaling receptor that plays an important role in supporting leukocyte diapedesis during the leukocyte adhesion cascade (4, 21). In contrast to this proinflammatory effect, PECAM-1 was shown in a number of situations to function as an ITIM-containing inhibitory receptor capable of dampening cellular activation events in lymphocytes (9, 22, 23), mast cells (24), and platelets (25-28). Numerous reports also demonstrated an anti-inflammatory role for PECAM-1 in well-established acute and chronic inflammatory disease models. For example, mice expressing PECAM-1 produce lower levels of inflammatory cytokines (7, 11-13), exhibit enhanced vascular barrier protection (10-12), and paradoxically, accumulate fewer leukocytes at sites of inflammation (10-13). However, the mechanisms by which PECAM-1 serves to confer protection in inflammation and how it regulates these aspects of the inflammatory response are still poorly understood.. One intriguing ...
The Mayo Clinic study is the first to identify an atrial fibrillation-associated genetic mutation of the ATP-sensitive potassium (KATP) channel. Researchers uncovered its role as a safeguard against atrial arrhythmia under stress conditions. The fail-safe mechanism present in most people to provide electrical stability to the heart under stress was defective in this patient. The sequencing of KATP channel genes, using genomic DNA extracted from the patients peripheral white blood cells, revealed a genetic mutation.. The discovery of the genetic mutations role in contributing to atrial fibrillation may ultimately improve physicians ability to identify patients who have a hereditary predisposition to atrial fibrillation, which is often complicated by increased risk for stroke and heart failure. Our findings support the emerging understanding of atrial fibrillation in younger patients as an inherited disease of ion channels, the building blocks of electrical pathways, says Timothy Olson, M.D., ...

In some countries, including India, the belief persists that watching a solar eclipse may be so stressful that it is bad for ones health. British researchers Omar Mian at Manchester University and Rubina Mian and Doug Thake at Coventry University were skeptical of tales about eclipses making people sick, and even causing deformities in unborn babies. To find out if there was any evidence either way, Rubina Mian took her graduate students to a field in Briey, France, to watch the 1999 summer eclipse. By analysing their blood samples with a luminometer, the researchers found that leukocyte activity increases by 8.7 percent during the eclipse. These white blood cells usually help our immune system, but if overstimulated they can damage DNA by releasing free radicals. Experiments after the eclipse showed that darkness, silence and temperature had no effect on leukocyte activity. But in other studies being prepared for publication, Rubina Mian has found that stress can have a big effect.. If ...
PolySia expression and function have been extensively studied in the nervous system, but the distribution and role of polySia in the immune compartment is still undefined. Herein we demonstrated the presence of polySia on human NK cells and its absence on other immune subsets, a finding that is in accord with two earlier reports (26, 27). NK cells up-regulated the expression of polySia and its scaffold NCAM upon activation by IL-2 treatment. This coregulation suggested that the heightened polySia signals were due to an up-regulation of both scaffold and glycan, rather than solely attributable to expanded polySia chain length. In support of this conclusion, a comparison of DP on resting and activated cells showed that upon activation total polySia was increased and the DP became more homogenous, tending toward small- to medium-length chains. To our knowledge, this is the first elucidation of polySia DP on primary human cells. The DP values we observed were slightly larger than analogous ...
The mechanisms of leukocyte recruitment have been studied extensively in vitro and have shed light on the basic molecular structure-function relationship of adhesion and signaling molecules involved in this essential immune response. This review will summarize how these in vitro observations extend to leukocyte behavior in inflamed blood vessels in the microcirculation. We highlight physiological results that might not have been predicted from in vitro systems. Special attention is placed on the physiology of rolling, adhesion, and intralumenal crawling in blood vessels. The importance of the glycocalyx, secondary tethers, shear, and the microenvironment are discussed. Docking structures forming rings of adhesion molecules together with a novel endothelial dome-like structure in vivo during transmigration are highlighted. Transcellular and paracellular emigration out of inflamed blood vessels is also discussed. The last section highlights leukocyte recruitment in some organs that do not always ...
The leukocyte adhesion cascade is an important paradigm of immunity and mediates leukocyte recruitment in acute or chronic inflammatory responses. Leukocyte recruitment requires several adhesive interactions between leukocytes and endothelial cells. The adhesion of leukocytes to the endothelial cell surface is mediated by interactions between leukocyte integrins, such as the beta1-integrin family member VLA-4 (a4b1) or the beta2-integrin family members LFA-1 (aLb2, CD11a/CD18), Mac-1 (aMb2, CD11b/CD18, complement receptor-3), and their endothelial counter-receptors of the immunoglobulin superfamily (ICAM-1, VCAM-1) (1). Our lab has made significant contributions to the leukocyte adhesion cascade, including the recent identification of a novel endogenous inhibitor of leukocyte recruitment, the endothelial-derived molecule Developmental Endothelial Locus-1 (Del-1, Edil3) (2-4).. Mobilization of hematopoietic stem cells (HSC) from the bone marrow to the periphery takes place upon infection. HSC ...

White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system.[1] All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. Types of white blood cells can be classified in standard ways. Two pairs of broadest categories classify them either by structure (granulocytes or agranulocytes) or by cell lineage (myeloid cells or lymphoid cells). These broadest categories can be further divided into the five main types: neutrophils, eosinophils (acidophiles), basophils, lymphocytes, and monocytes.[2] These types are distinguished by their physical and functional ...
Introduction: Psoriasis vulgaris (PV) is a chronic skin disease, mediated by environmental risk factors and aberrant immune response to unknown antigens. CD8+ cytotoxic lymphocytes make a large proportion of the leukocyte infiltrate. Their secretion of IL-17/IFN-γ/TNF-α helps in growing inflammatory state in a skin, keratinocytes proliferation and dedifferentiation and consequently, forming scaly plaques. Objectives: To examine and compare frequency of CD3+CD8+ T lymphocytes in PV patients and healthy controls and determine their association with demographic and clinical features of psoriasis. Material and methods: Peripheral blood was collected from 21 PV patients and 22 healthy controls. Peripheral leukocytes were isolated during centrifugation in density gradient Lymphoprep™ medium. Dead cells were excluded with „LIVE/DEAD™ Fixable Dead Cell Stain Kit. Immunophenotyping CD3+CD8+ T lymphocytes was performed on a flow cytometry (BD FACS Canto II) after labeling samples with anti-human ...
Clone 390 reacts with the cell surface protein CD31. The murine CD31 antigen is also known as PECAM-1. The encoded protein is a single-pass type I membrane protein containing six Ig-like C2-type (immunoglobulin-like) domains and functions as cell adhesion molecule. CD31 is present on mature endothelial cells as well as on most leukocyte subtypes and platelets where the expression level can vary. Besides its function in exhibiting adhesive properties, the protein is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions. | Belgique
The liver plays a major role for the metabolism, but it is also of general importance for the immune system, e.g. for the deletion of activated T cells or the induction of peripheral tolerance. Under physiological conditions T cells and other leukocytes can be found in the liver, in the sinusoids as well as in the parenchyma. This hepatic accumulation of T cells might be due to immunosurveillance, but it would also be a prerequisite for modulation of T cells by hepatic cells. The present study investigated two different aspects of the interaction of liver sinusoidal endothelial cells (LSEC), the barrier between the sinusoidal lumen and the hepatic parenchyma, and CD4+ T cells. In the first part of the study it could be demonstrated that LSEC support the spontaneous transmigration of CD4+ T cells as well as their chemotaxis to CXCL12 and CXCL9 more efficiently than other endothelial cells. Whereas a direct endothelial activation by chemokines could be excluded the efficient chemokine presentation ...
Aside from nutritional significance, milk affords infant mammals immunologic benefits. However, it is not without immunologically based hazards. These stem from its antigenicity and the fact that in certain species that receive their maternal immunologic endowment postpartum, hemolytic disease of the newborn may be mediated by colostral antibodies. Awareness that viable leukocytes are ingredients of colostrum and milk has stimulated interest in the significance of these cells. Skin grafting tests on foster-nursed rats and mice have given circumstantial evidence that, in these species, leukocytes may be transmitted naturally from the mothers blood stream to the sucklings blood stream through the milk, and that these cells may be beneficial (adoptive immunization) or, in some genetic contexts, harmful (initiating graft-versus-host disease). In man, too, studies on necrotizing enteritis and other diseases provide increasing support for the thesis that leukocytes in milk fulfill a protective ...

© 2016 International Union of Biochemistry and Molecular Biology Type 1 diabetes mellitus (T1DM) results from immune cell-mediated reductions in function and mass of the insulin-producing β-cells within the pancreatic islets. While the initial trigger(s) that initiates the autoimmune process is unknown, there is a leukocytic infiltration that precedes islet β-cell death and dysfunction. Herein, we demonstrate that genes encoding the chemokines CXCL9, 10, and 11 are primary response genes in pancreatic β-cells and are also elevated as part of the inflammatory response in mouse, rat, and human islets. We further established that STAT1 participates in the transcriptional control of these genes in response to the pro-inflammatory cytokines IL-1β and IFN-γ. STAT1 is phosphorylated within five minutes after β-cell exposure to IFN-γ, with subsequent occupancy at proximal and distal response elements within the Cxcl9 and Cxcl11 gene promoters. This increase in STAT1 binding is coupled to the rapid

Cellular hypersensitivity to an extract of human pancreas, using the leucocyte migration test (LMT), was found in twenty-nine of 101 diabetic and eight of fifty normal control subjects. However, the difference in response between diabetics and controls was confined to young insulin-dependent patients, there being no distinction between normal subjects and older diabetics treated by diet or oral hypoglycemic agents. The use of rat liver mitochondria and bovine insulin as antigens in the LMT did not induce inhibition of leucocyte migration in diabetics or controls.. ...

Octanoate and palmitate beta-oxidation in human leukocytes: implications for the rapid diagnosis of fatty acid beta-oxidation disorders.:
White blood cells, or leucocytes (also spelled leukocytes, from the Greek word leuko-, meaning white), are a component of blood. As part of the bodys immune system, their function is to protect the body from disease and infection if pathogens get in the bloodstream. White blood cells come in several varieties, each with a different role to play in neutralizing harmful foreign substances. White blood cells, like all blood cells, are produced in the bone marrow. They are also known as leukocytes. There are many types of leukocytes, and these types are produced from immature cells in the lymphatic system in response to the bodys needs. For example, infection with bacteria will cause more macrophages to be produced and fewer NK cells, in response to alarm signals called chemokines. Macrophages then exit the bloodstream, migrate towards the site of infection, and attempt to neutralize the invading pathogens. Others begin producing antibodies or recruit other systems to help. The immune system of ...
The immune system works through leukocytes interacting with each other, with other cells, with tissue matrices, with infectious agents, and with other antigens. These interactions are mediated by cell-surface glycoproteins and glycolipids. Antibodies against these leukocyte molecules have provided powerful tools for analysis of their structure, function, and distribution. Antibodies have been used widely in hematology, immunology, and pathology, and in research, diagnosis, and therapy. The associated CD nomenclature is commonly used when referring to leukocyte surface molecules and antibodies against them. It provides an essential classification for diagnostic and therapeutic purposes. The most recent (8th) Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA), held in Adelaide, Australia, in December 2004, allocated 95 new CD designations and made radical changes to its aims and future operational strategy in order to maintain its relevance to modern human biology and clinical
Biological measures of aging are important for understanding the health of an aging population, with epigenetics particularly promising. Previous studies found that tumor tissue is epigenetically older than its donors are chronologically. We examined whether blood Δage (the discrepancy between epigenetic and chronological ages) can predict cancer incidence or mortality, thus assessing its potential as a cancer biomarker. In a prospective cohort, Δage and its rate of change over time were calculated in 834 blood leukocyte samples collected from 442 participants free of cancer at blood draw. About 3-5 years before cancer onset or death, Δage was associated with cancer risks in a dose-responsive manner (P = 0.02) and a one-year increase in Δage was associated with cancer incidence (HR: 1.06, 95% CI: 1.02-1.10) and mortality (HR: 1.17, 95% CI: 1.07-1.28). Participants with smaller Δage and decelerated epigenetic aging over time had the lowest risks of cancer incidence (P = 0.003) and mortality ...
An improved multi-purpose blood diluent for use with a gentle lysing agent and improved detergent reagent system are disclosed which are especially suitable for use in routine electronic enumeration and volumetric differentation of blood cells. The preferred imidazole stabilizer used in the diluent reagent is found to be an excellent cell stabilizing agent and buffer for maintaining cell morphology during operation. A synergistic combination of a superior antimicrobial agent, the preferred Triadine-10, used in the diluent and the detergent reagents, not only prevents bacterial or fungal growth, but also helps to stabilize cells and to obtain distinct volumetric differentiation of certain leukocyte subpopulations. The preferred Brij 35 in a balanced salt solution has proved to be an efficient and cost effective detergent to ensure accurate results and trouble-free operation of the analyzers.

Helpful, trusted answers from doctors: Dr. Dohan on white blood cells in urine no infection: White blood cells in urine usually are there because of an infection in the urinary tract. However, they can also be there in large numbers in a female when there is a vaginal infection or when she is having her period (always see red cells also in this situation). My best advice is to see your doctor and have a urine culture done to see what is going on.
