摘要在不同细胞因子以及不同浓度的细胞因子作用下原始CD4 + T细胞可分化为不同的Th亚群。辅助性T细胞17（Th17）和调节性T细胞（Treg细胞）是近年的研究热点，两者通过分泌不同的效应细胞因子发挥不同的免疫调节作用，即相互区别又相互联系，其中具体调控机制复杂，均在非小细胞肺癌（NSCLC）的发生中发挥重要作用。文章就Th17和Treg细胞的分化、发育、免疫学作用及对NSCLC的免疫调节作用的研究进展进行综述。

abstractsUnder the regulation of various cytokines and different concentrations of cytokines, primary CD4 + T cells can differentiate into different Th subgroups. T helper cells 17 (Th17) and regulatory T cells (Treg cells) are research hotspots in recent years. They play diverse immunomodulatory roles by secreting various target cytokines. Th17 and Treg cells are different from each other but connect with each other, their regulatory mechanism is complex, and they play important roles in non-small cell lung cancer (NSCLC). This paper reviews the progress of the differentiation, the development and the immunological function of Th17 and Treg cells and their immunomodulatory effect on the NSCLC.
