缺乏白细胞介素-23(IL-23)的小鼠对T细胞介导的自身免疫具有抗性。虽然IL-23是辅助性T细胞17(Th 17)的成熟因子,但γδ T细胞的亚群组成性地表达IL-23受体(IL-23 R)。利用IL-23 R报告基因小鼠,我们发现γδ T细胞是实验性自身免疫性脑脊髓炎(EAE)中最先对IL-23产生应答的细胞。尽管γδ T细胞响应于IL-23产生Th 17细胞相关的细胞因子,但它们的主要功能是防止调节性T(Treg)细胞应答的发展。IL-23活化的γδ T细胞使αβ效应T细胞对Treg细胞的抑制活性不敏感,并且还阻止了常规T细胞在体内转化为Foxp 3 + Treg细胞。因此,IL-23本身对Treg细胞没有直接影响,但能够解除Treg细胞应答并通过活化γδ T细胞促进抗原特异性效应T细胞应答。
Mice that lack interleukin-23 (IL-23) are resistant to T cell-mediated autoimmunity. Although IL-23 is a maturation factor for T helper 17 (Th17) cells, a subset of γδ T cells expresses the IL-23 receptor (IL-23R) constitutively. Using IL-23R reporter mice, we showed that γδ T cells were the first cells to respond to IL-23 during experimental autoimmune encephalomyelitis (EAE). Although γδ T cells produced Th17 cell-associated cytokines in response to IL-23, their major function was to prevent the development of regulatory T (Treg) cell responses. IL-23-activated γδ T cells rendered αβ effector T cells refractory to the suppressive activity of Treg cells and also prevented the conversion of conventional T cells into Foxp3+ Treg cells in vivo. Thus, IL-23, which by itself has no direct effect on Treg cells, is able to disarm Treg cell responses and promote antigen specific effector T cell responses via activating γδ T cells.
