信号3细胞因子,如IL-12或I型IFN,支持体内CD 8 T细胞的扩增和分化。这两种信号3细胞因子在不同感染期间是否以及如何在T细胞活化中相互补偿至今尚不清楚。使用缺乏IL-12,I型IFN或两者的受体的CD 8 T细胞,我们表明,CD 8 T细胞的扩增依赖于I型IFN(LCMV感染),I型IFN和IL-12(李斯特菌和水泡性口炎病毒感染)或在很大程度上独立于两种细胞因子(牛痘病毒感染)。此外,我们表明,缺乏IL-12和I型IFN信号的CD 8 T细胞在VSV和李斯特菌感染的背景下细胞因子产生和细胞溶解活性受损。这些效应CD 8 T细胞不能表达KLRG 1,从而表现出记忆样表型,其与转录因子T-bet的较低表达和Eomes的较高表达相关。这表明两种信号3细胞因子的可变相互作用对于在不同感染的情况下CD 8 T细胞的细胞命运决定是强制性的。此外,我们的研究结果表明,病原体诱导的整体炎症环境,而不是抗原负荷和/或抗原呈递的质量决定了CD 8 T细胞的信号3依赖性。
Signal 3 cytokines, such as IL-12 or type I IFN, support expansion and differentiation of CD8 T cells in vivo. If and how these two signal 3 cytokines compensate each other in T cell activation during different infections is so far unknown. Using CD8 T cells lacking receptors for IL-12, type I IFN or both, we show that the expansion of CD8 T cells depends on type I IFN (LCMV infection), type I IFN and IL-12 (Listeria and vesicular stomatitis virus infection) or is largely independent of the two cytokines (vaccinia virus infection). Furthermore, we show that CD8 T cells lacking IL-12 and type I IFN signals are impaired in cytokine production and cytolytic activity in the context of VSV and Listeria infection. These effector CD8 T cells fail to express KLRG1, thereby exhibiting a memory-like phenotype which correlated with lower expression of the transcription factor T-bet and higher expression of Eomes. This indicates that the variable interplay of both signal 3 cytokines is mandatory for cell fate decision of CD8 T cells in the context of different infections. Furthermore our results demonstrate that the pathogen-induced overall inflammatory milieu and not the antigen load and/or the quality of antigen presentation critically determine the signal 3 dependence of CD8 T cells.
