Rheumatoid arthritis (RA) is an autoimmune disorder which shows production of autoantibodies, inflammation, bone erosion, swelling and pain in joints. In this study, we examined the effects of an immune-modulating peptide, WKYMVm, that is an agonist for formyl peptide receptors (FPRs). Administration of WKYMVm into collagen-induced arthritis (CIA) mice, an animal model for RA, attenuated paw thickness, clinical scores, production of type II collagen-specific antibodies and inflammatory cytokines. WKYMVm treatment also decreased the numbers of TH1 and TH17 cells in the spleens of CIA mice. WKYMVm attenuated TH1 and TH17 differentiation in a dendritic cell (DC)-dependent manner. WKYMVm-induced beneficial effects against CIA and WKYMVm-attenuated TH1 and TH17 differentiation were reversed by cyclosporin H but not by WRW4, indicating a crucial role of FPR1. We also found that WKYMVm augmented IL-10 production from lipopolysaccharide-stimulated DCs and WKYMVm failed to suppress TH1 and TH17 differentiation in the presence of anti-IL-10 antibody. The therapeutic administration of WKYMVm also elicited beneficial outcome against CIA. Collectively, we demonstrate that WKYMVm stimulation of FPR1 in DCs suppresses the generation of TH1 and TH17 cells via IL-10 production, providing novel insight into the function of FPR1 in regulating CIA pathogenesis.

甲酰肽受体 1 的激活对胶原诱导的关节炎产生治疗作用

类风湿性关节炎 (RA) 是一种自身免疫性疾病,表现为自身抗体的产生、炎症、骨侵蚀、关节肿胀和疼痛。在这项研究中,我们检查了免疫调节肽 WKYMVm 的作用,它是甲酰肽受体 (FPR) 的激动剂。将 WKYMVm 给药到胶原诱导的关节炎 (CIA) 小鼠(一种 RA 的动物模型)中,减少了爪子的厚度、临床评分、II 型胶原特异性抗体和炎性细胞因子的产生。WKYMVm 治疗还减少了CIA 小鼠脾脏中T H 1 和 T H 17 细胞的数量。WKYMVm 衰减 T H 1 和 T H17 以树突状细胞 (DC) 依赖性方式分化。WKYMVm 诱导的对 CIA 和 WKYMVm 减弱的 T H 1 和 T H 17 分化的有益作用被环孢菌素 H 而不是 WRW4 逆转,表明 FPR1 的关键作用。我们还发现 WKYMVm 增加了脂多糖刺激的 DCs 的 IL-10 产生,并且 WKYMVm在抗 IL-10 抗体存在下未能抑制 T H 1 和 T H 17 分化。WKYMVm 的治疗性给药也对 CIA 产生了有益的结果。总的来说,我们证明了 DCs 中 FPR1 的 WKYMVm 刺激抑制了 T H 1 和 T H的产生17 个细胞通过 IL-10 产生,提供了对 FPR1 在调节 CIA 发病机制中的功能的新见解。
