通过与白细胞介素17受体(IL-17R)结合,TRAF3阻止IL-17R-Act1-TRAF6复合体的形成,并抑制下游信号转导。白介素17(IL-17)在包括实验性自身免疫性脑脊髓炎(EAE)在内的多种自身免疫性疾病的发病机制中起重要作用。这种强大的炎症细胞因子是如何控制信号以避免异常炎症反应的,目前尚不清楚。在本研究中,我们报道了TRAF3是IL-17受体(IL-17R)信号的受体近端负调节因子。TRAF3可显著抑制IL-17诱导的NF-κB和丝裂原活化蛋白激酶的激活,以及随后炎性细胞因子和趋化因子的产生。从机制上讲,TRAF3与IL-17R的结合干扰了IL-17R-Act1-TRAF6受体信号激活复合体的形成,导致下游信号的抑制。TRAF3在体内可明显抑制IL-17诱导的炎性细胞因子和趋化因子基因的表达,从而延缓EAE的发病,显著降低EAE的发生率和严重程度。因此,TRAF3是IL-17R近端信号的负调控因子。
By binding to the interleukin 17 receptor (IL-17R), TRAF3 blocks formation of the IL-17R–Act1–TRAF6 complex and inhibits downstream signaling. Interleukin 17 (IL-17) plays critical roles in the pathogenesis of various autoimmune diseases, including experimental autoimmune encephalomyelitis (EAE). How the signals triggered by this powerful inflammatory cytokine are controlled to avoid abnormal inflammatory responses is not well understood. In this study, we report that TRAF3 is a receptor proximal negative regulator of IL-17 receptor (IL-17R) signaling. TRAF3 greatly suppressed IL-17–induced NF-κB and mitogen-activated protein kinase activation and subsequent production of inflammatory cytokines and chemokines. Mechanistically, the binding of TRAF3 to IL-17R interfered with the formation of the receptor signaling activation complex IL-17R–Act1–TRAF6, resulting in suppression of downstream signaling. TRAF3 markedly inhibited IL-17–induced expression of inflammatory cytokine and chemokine genes in vivo and consequently delayed the onset and greatly reduced the incidence and severity of EAE. Thus, TRAF3 is a negative regulator of IL-17R proximal signaling.
