查询词典 antigen

As a functionally and phenotypically distictive T cell subpopulation,CD4+CD25+ regulatory T cells are anergic and retain their ability to suppress antigen-driven response of CD4+CD25- cells in a contact-dependent manner or through a way of secreting immunosuppressive cytokines such as IL-10 and TGF-β.

CD4+CD25+调节性T细胞是一群表型和功能特异的T细胞亚群，具有免疫无能和免疫抑制两大特性，通过细胞直接接触或分泌抑制性细胞因子发挥对CD4+CD25-T细胞的抑制作用。
