Activating and inhibitory cell surface receptors play important roles in regulation of immune responses. Recent progress has demonstrated that many inhibitory receptors pair with activating, as well as inhibitory, isoforms, both of whose genes are located in small clusters on a chromosome. We and others identified paired activating and inhibitory immunoglobulin-like receptors, designated myeloi...

in this study 71 head of conceiving ewe and their progeny (91 head) from the flock of lori-bakhtiari sheep (360 head), in sholi station were randomly selected to determine the relationship between the immunoglobulin (igg) concentration in the ewe's serum and colostrum, and lamb's serum. ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...

abstract: chronic lymphocyte leukemia (cll) is the most common leukemia in elderly individuals that is accompanied by the presence of cd5/cd19/cd20/cd23 positive, fmc7 negative and reduced levels of surface membrane immunoglobuline (igm & igd), cd79b on b lymphocytes in the blood, bone marrow and lymph nodes. remarkably, based on the mutational igvh status, b-cll cases can be subdivided into tw...

humans suffer transient or persistent starvation due to a lack of food intake, either because of fasting, voluntary dieting, or due to the scarcity of available food. at the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of enric...

Le déficit sélectif en IgA (DSIgA) est défini par l’European Society for Immunodeficiencies (ESID) comme un taux d’IgA sériques inférieur à 0,07 g/L avec normal d’IgG et d’IgM, une réponse vaccinale normale, chez patient de plus 4 ans, après exclusion des autres causes d’hypogammaglobulinémie. Quand le supérieur mais deux déviations standard au-dessous la valeur normale pour l’âge, il s’agit d’...

background and objective: lowering serum glucose and lipid levels in diabetic patients by using natural materials is of great importance. in this study, the effect of oral consumption of fumaria parviflora lamwas was assessed on serum glucose and lipid levels in streptozocin diabetic rats. materials and methods: in this experimental study, 32 male wistar rats were divided into four groups of co...

genus leishmania is a protozoan parasite that causes different severe diseases. fetal calf serum (fcs) is the major part of the leishmania culture media, for mass cultivation and the most expensive ingredient in these media. in the present work, the efficacy of chicken serum was evaluated in leishmania culture media. the results indicated that, the (10%) chicken serum enriched culture medium su...
