CD4+ effector T cells effectuate T cell immune responses, producing cytokines to orchestrate the nature and type of immune responses. The non-receptor tyrosine kinase IL-2 inducible T cell kinase (ITK), a mediator of T cell Receptor signaling, plays a critical role in tuning the development of these effector cells. In this review we discussed the role that signals downstream of ITK, including the Ras/MAPK pathway, play in differentially controlling the differentiation of TH17, Foxp3+ T regulatory (Treg) cells, and Type 1 regulatory T (Tr1) cells, supporting a model of ITK signals controlling a decision point in the effector T cell differentiation process.
CD4+效应 T 细胞实现 T 细胞免疫应答,产生细胞因子来协调免疫应答的性质和类型。非受体酪氨酸激酶白细胞介素 2 诱导的 T 细胞激酶 (ITK) 是 T 细胞受体信号转导的介质,在调节这些效应细胞的发育中起着关键作用。在这篇综述中,我们讨论了 ITK 下游信号(包括 Ras/MAPK 途径)在差异控制 TH17、Foxp3+T 调节(Treg)细胞和 1 型调节性 T(Tr1)细胞分化中的作用,支持 ITK 信号控制效应 T 细胞分化过程中的决策点的模型。
