Interleukin-3-induced downregulation of the expression of interleukin-2 receptor beta chain in human T cells.
We examined the effect of interleukin-3 (IL-3) on human CD4+ cloned T cells, P607 and 1C2. By flow cytometric analysis, we found that IL-3 downregulated the surface expression of IL-2 receptor (R) beta chain in a dose-dependent manner but had little effect on that of IL-2R alpha chain. A simultaneous 125I-labeled IL-2 binding assay showed a decrease in the number of high-affinity, but not of lo...

Introduction: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role Background and Objective: Interleukin-2 (IL-2) as a T helper type 1 (Th1) cytokine has an important role in activation, growth and differentiation of several immune cells. Moreover IL-2 is known as a pro-inflammatory and anti-tumoral cytokine. In addition deysregulation of IL-2 in some diseases such as ...
متن کاملP-33: Expression of Toll-Like Receptor 2-3 Genes in Human Sertoli Cells
Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...
متن کاملInduction of interleukin 2 receptor beta chain expression by self- recognition in the thymus
1-2% of adult mouse thymocytes express the T cell receptor alpha/beta (TCR-alpha/beta) together with the interleukin (IL) 2R beta (p70), but not the alpha (p 55) chain. We show that the previously described alpha/beta-TCR +CD4-8- and the partially overlapping Ly6C+ thymocytes are contained within this subset. Most IL-2R beta+ alpha/beta-TCR+ cells have a mature and activated (heat stable antige...
متن کاملExpression of interleukin-2 receptor beta subunit in hematopoietic malignancies.
The expression of the interleukin-2 (IL-2) receptor was studied in neoplastic cells derived from acute leukemias, T-cell lymphoblastic lymphomas, peripheral T-cell lymphomas, chronic lymphocytic leukemias, well-differentiated lymphocytic lymphomas, and established cell lines by both flow cytometric analysis and sodium dodecyl sulfate/polyacrylamide gel electrophoresis (SDS-PAGE) after affinity ...
