摘要:

目的:探讨天山雪莲口服液(SIOL)改善胶原诱导性关节炎(CIA)的机制,分析SIOL对巨噬细胞极化和Notch1信号轴的调控作用,旨在为类风湿关节炎(RA)治疗提供新的分子靶点。方法:将60SPF级雄性SD大鼠,随机分为正常组、模型组、雷公藤多苷片(TGT)组和SIOL低、中、高剂量组。建立CIA大鼠模型,治疗组分别给予相应剂量的SIOLTGT。观察各组大鼠关节肿胀程度,关节组织病理变化经HEMasson染色显现;ELISA检测各组炎症因子水平;流式细胞术检测外周血CD86CD163标志物水平;Western Blot 检测大鼠关节滑膜组织中iNOSArg-1Notch1信号通路相关蛋白的表达。结果:模型组大鼠关节出现组织受损、组织增生、纤维化及炎症浸润等特征改变,踝关节直径和足趾容积、关节炎指数(AI)、肿瘤坏死因子-αTNF-α)、白介素(IL)-IL-6水平及外周血CD86表达和滑膜中iNOSNotch1通路相关蛋白表达占比均升高(P<0.05),IL-10IL-4水平、外周血CD163表达和滑膜中Arg-1表达均降低(P<0.05)。与模型组相比,SIOL降低CIA大鼠关节肿胀、血清TNF-αIL-IL-6(除SIOL低剂量组)水平、外周血CD86和滑膜中iNOSNotch1信号通路相关蛋白表达(P<0.05);同时,增加血清IL-10IL-4水平及外周血CD163(除SIOL低剂量组)表达和滑膜中Arg-1表达(P<0.05)。结论:SIOL可有效减轻CIA大鼠关节炎症反应,其机制可能与抑制Notch1信号通路轴调控巨噬细胞极化,抑制促炎细胞因子的分泌有关。

Abstract:

Objective: To explore the mechanism by which saussurea involucrata oral liquid SIOL improves collagen-induced arthritis CIA), focusing on its regulatory effects on macrophage polarization and the Notch1 signaling pathway providing a new molecular target for the treatment of rheumatoid arthritis RA.Methods: Sixty specific pathogen-free SPF male sprague-dawley SD rats were randomly divided into the normal group model group tripterygium wilfordii tablet TGT group and SIOL low medium and high dose groups. A CIA rat model was established and the treatment groups were administered with corresponding doses of SIOL or TGT. The degree of joint swelling in each group of rats was observed and histopathological changes in joint tissues were revealed by H&E and Masson staining. ELISA was used to detect the levels of inflammatory factors in each group.The expression levels of peripheral blood CD86 and CD163 markers were detected by flow cytometry.Meanwhile Western Blot was utilized to detect the expression of iNOS Arg-1 and Notch1 signaling pathway related proteins in the synovial tissue of rats.Results: In the model group rats exhibited characteristic pathological changes in joint tissues including tissue damage hyperplasia fibrosis and inflammatory infiltration. Significant increases were observed in ankle joint diameter paw volume arthritis index AI), serum levels of tumor necrosis factor-α TNF-α), interleukin-IL-), and IL-6 as well as peripheral blood CD86+ cell proportion and synovial expression levels of iNOS and Notch1 signaling pathway-related proteins P < 0.05.Conversely serum levels of IL-10 and IL-4 peripheral blood CD163+ cell proportion and synovial Arg-1 expression were significantly reduced P < 0.05. Compared with the model group SIOL treatment significantly alleviated joint swelling decreased serum TNF-α IL- and IL-6 levels except in the SIOL low-dose group), reduced peripheral blood CD86+ cell proportion and synovial iNOS and Notch1 pathway-related protein expression P < 0.05. Additionally SIOL upregulated serum IL-10 and IL-4 levels peripheral blood CD163+ cell proportion except in the SIOL low-dose group), and synovial Arg-1 expression P < 0.05.Conclusion: SIOL can effectively alleviate the joint inflammatory response in CIA rats and its mechanism may be related to the inhibition of the Notch1 signaling pathway which regulates macrophage polarization and suppresses the secretion of pro-inflammatory cytokines.
