the immune responses that develop following epstien-barr virus (ebv) infection are complex and involve both humoral and to a greater extent cell-mediated immune mechanisms. to evaluate the immune response, flow cytometric analysis of the peripheral blood of six patients during the acute phase of ebv infection was performed. this analysis revealed a significant increase in the percentages and th...

contact hypersensitivity (chs) mouse model induced by 2, 4-dinitrofluorobenzene (dnfb) is thought to be a t helper 1 (th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. however, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. in this study, we focused on whether t lym...

The immune system of 90-day old piglets SM-1 Novosibirsk breed depends on sex and stress-reactivity. Stress-reactivity was measured using halothane test. immunologic testing performed 30 days after weaning. Our results show that overall piglet demonstrated high proliferative activity T- B- immunocompetent cells with active formation mature T-and B-lymphocytes did not signs immunosuppression. Co...

background lichen planus is a disease with unknown etiology that affects the skin and the mucous membranes. immune dysregulation in the pathogenesis of oral lichen planus (olp) is well-known phenomenon. objectives in this study, we compared the levels of the peripheral blood t lymphocytes between patients with olp and control group. patients and methods in this study, 32 and 16 patients respect...

background: cd4+ and cd8+ t cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. the frequencies of t cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dln) can be considered as useful markers for evaluation of the immune system in cancers. methods: in this study,...

background : an elevation in the mean percentages of the gamma delta t lymphocytes per total t cells in the epithelium of the small intestine has a diagnostic value for celiac disease.  this study aimed to measure the percentages of the peripheral blood gamma delta t lymphocytes in the adults' celiac disease and healthy controls. materials and methods: in this case-control study the absolute nu...

glycoconjugates and their programmed changes during the course of development in the cell-surface as well as in the extracellular matrix, are known to affect cell differentiation, cellular interaction and other developmental phenomena during embryogenesis. the purpose of this study was to localize n-acetylgalactosamin as well as fucose-containing glycoconjugates in situ during thymus developmen...
