WebJan 27, 2014 · Our laboratory has identified a critical role of IL-9 in promoting endogenous tumor-specific cytotoxic T lymphocyte response. In this study, we found that differentiation of CD8 + T cells under T helper 9-polarizing conditions induces the development of an IL-9–producing less cytolytic IL-9–skewed CD8 + T (Tc9) cell subset. Noticeably, adoptive … WebCD8+ T cells play a crucial role in eliminating virus-infected cells and tumors. Armed with potent cytolytic potential and an inherent capacity to produce proinflammatory cytokines, CD8+ T cells are generally highly effective at killing their target cells upon T cell receptor (TCR) recognition of cognate antigen presented in the context of MHC-I [1].
