CD4~+T细胞被激活后会分化为不同的具有特异生物学功能的辅助性T细胞。分泌IL-9的Th9细胞是新近被鉴定出的一种具有独立功能的效应T细胞亚群,它与变态反应性疾病、自身免疫性疾病和肿瘤等多种疾病关系密切,本文对Th9细胞的生物学特点及其在疾病中的最新研究进展作一综述。
After CD4 ~ + T cells are activated, they differentiate into different T helper cells with specific biological functions. Th9 cells secreting IL-9 is a newly identified subset of effector T cells with independent function. It is closely related to many diseases such as allergic diseases, autoimmune diseases and tumors. In this paper, Biological characteristics and the latest research progress in the disease are reviewed.
