针对类风湿关节炎分子靶点的治疗药物研究进展

治疗类风湿关节炎(rheum atoid arthritis,RA)的药物虽有很多,但由于RA的发病机制和病因还没有完全阐明,目前还没有一种药物能够根治RA。随着对炎症过程的认识不断深入,特别对信号转导路径的认识,人们一直努力找寻一些调理疾病进程的具有特异性的干扰信号转导路径新的治疗药物。TNF-α阻断剂和IL-1受体拮抗剂等细胞因子拮抗剂在临床试验中治疗RA起到明显的效果。调节滑膜细胞G蛋白-AC-cAMP和Ras-MAPKs信号通路是中药白芍总苷和木瓜总苷发挥抗滑膜细胞增殖的重要分子机制。该文将对一些以细胞因子、炎症介质、细胞表面抗原、信号转导为靶点的药物研究情况进行综述。

Study of therapeutic drugs on molecular targets in rheumatoid arthritis

There are many therapeutic drugs for rheumatoid arthritis(RA) treatment,but the pathogenesis of RA have not been fully understood,therefore no curable drug has been found.With increasing knowledge of the inflammatory process,especially in signaling,some drugs modifying disease progress and interfering signaling pathways have been studied.Cytokine inhibitors such as tumor necrosis factor-blocking agents and IL-1 receptor antagonist in clinical trials and in practice have resulted in dramatic improvement in RA disease control.Important molecular mechanisms of actions on total glucosides of paeony(TGP) and Glucosides of Chaenomeles speciosa(GCS) were showed to modulate G protein-AC-cAMP and Ras-MAPKs signaling pathways and to inhibit synoviacytes proliferation.This review focuses on agents which target various cytokines,other inflammatory mediators,antigen of cells,and signaling pathways.
