In this report, we describe a novel activation antigen that appears very early after T cell activation and is absent in resting lymphocytes, through which agonistic proliferative signals can be triggered by mAb binding. It has been designated as activation inducer molecule (AIM) and is a disulphide-linked heterodimeric structure containing two polypeptide chains of Mr 33,000 and 27,000. The exp...
مقدمه: به نظر می رسد سلول های موثر و مرتبط با سقط جنین مکرر شامل دو گروه لنفوسیت های t و سلول های کشنده طبیعی(nk) باشند. ما در این مطالعه به بررسی درصد و تعداد مطلق سلول های کشنده طبیعی +cd16+/56 و سلول های cd16+/56+bright و cd16+/56+dim موجود در خون محیطی پرداخته، همچنین با بررسی مارکرهای cd69/cd56، درصد و تعداد مطلق سلول های کشنده طبیعی فعال شده در خون محیطی بیماران مبتلا به سقط جنین مکررو ز...
Over recent decades, multiple data were accumulated on immunotropic activity of Bifidum flora, based effects these bacteria isolated lymphoid follicles, dendritic cells, B-cell aggregates, pro- and anti-inflammatory cytokines chemokines, as well participation bifidoflora in the recognition non-self during development microsymbiocenosis. The relevance research field is associated both with funda...
EBV infection is more common in patients with systemic lupus erythematosus (SLE) than in control subjects, suggesting that this virus plays an etiologic role in disease and/or that patients with lupus have impaired EBV-specific immune responses. In the current report we assessed immune responsiveness to EBV in patients with SLE and healthy controls, determining virus-specific T cell responses a...
OBJECTIVES Non-obese diabetic (NOD) mice develop spontaneous type 1 diabetes. We have shown that sphingosine-1-phosphate (S1P) reduces activation of NOD diabetic endothelium via the S1P1 receptor. In the current study, we tested the hypothesis that S1P could inhibit CD4(+) T-cell activation, further reducing inflammatory events associated with diabetes. RESEARCH DESIGN AND METHODS CD4(+) T-ce...
