T细胞按功能不同可分为辅助性T细胞(T helper cell,Th)、细胞毒性T细胞(cytotoxic T cell,Tc)和调节性T细胞(regulatory T cells,Treg),其中Th细胞根据分泌细胞因子谱的差异又可分为Th1和Th2两个亚群[1]。Thl和Th2细胞在感染性疾病的发病过程中发挥着重要的作用,它们分别通过介
T cells can be divided into T helper cells (Th), cytotoxic T cells (Tc) and regulatory T cells (Tregs) according to different functions. The Th cells are classified according to the secretory cells Factor spectrum differences can be divided into two sub-groups Th1 and Th2 [1]. Th1 and Th2 cells play an important role in the pathogenesis of infectious diseases,
