辅助性T细胞17(T helper 17 cell,Th17)是一种以分泌IL-17为主要特征的新型CD4+T细胞亚群。CD4+T细胞分为效应T细胞和调节性T细胞(regulatory T cells,Treg)两类。传统观念根据分泌细胞因子的不同又将效应T细胞分为两型:一型能产生IFN-γ的Thl细胞,参与介导细胞免疫应答;另一型
T helper 17 cell (Th17) is a novel subsets of CD4 + T cells characterized by the secretion of IL-17. CD4 + T cells are divided into effector T cells and regulatory T cells (Tregs). The traditional concept according to the different secretion of cytokines in turn the effect of T cells are divided into two types: one can produce Th1 IFN-γ cells, involved in the induction of cellular immune response; the other type
