在微生物感染后,防止产生白细胞介素 - 17的辅助性T细胞(Th17)出现不适当或过度反应的机制对于避免自身免疫可能是必要的。在此,我们确定了一条由树突状细胞(DC)表达的I型干扰素受体(IFNAR)参与而启动的通路,该通路最终抑制了Th17细胞的分化。IFNAR对骨桥蛋白的一种细胞内翻译异构体(称为Opn - i)的依赖性抑制解除了对白介素 - 27(IL - 27)分泌的抑制,并阻止了有效的Th17反应。此外,树突状细胞和小胶质细胞中Opn - i的表达调节了实验性自身免疫性脑脊髓炎(EAE)的类型和强度。与Opn充足小鼠的主要Th17反应相比,含有Opn - i缺陷的树突状细胞的小鼠产生过量的IL - 27,并发展出一种延迟性疾病,其特征是Th1反应增强。对控制Th17发育的IFNAR - Opn - i轴的确定为辅助性T细胞亚群发育的调控以及I型干扰素治疗多发性硬化症和其他自身免疫性疾病的分子基础提供了见解。
Mechanisms that prevent inappropriate or excessive interleukin-17-producing T helper (Th17) cell responses after microbial infection may be necessary to avoid autoimmunity. Here, we define a pathway initiated by engagement of Type-I IFN receptor (IFNAR) expressed by dendritic cells (DC) that culminated in suppression of Th17 cell differentiation. IFNAR-dependent inhibition of an intracellular translational isoform of Osteopontin, termed Opn-i, de-repressed interleukin-27 (IL-27) secretion and prevented efficient Th17 responses. Moreover, Opn-i expression in DC and microglia regulated the type and intensity of Experimental Autoimmune Encephalomyelitis (EAE). Mice containing DC deficient in Opn-i produced excessive amounts of IL-27 and developed a delayed disease characterized by an enhanced Th1 response compared with the dominant Th17 response of Opn sufficient mice. Definition of the IFNAR Opn-i axis that controls Th17 development provides insight into regulation of Th sublineage development and the molecular basis of Type I interferon therapy for MS and other autoimmune diseases.
