Fleishaker and colleagues reported on a double-blind placebo controlled clinical trial of a C-C chemokine-receptor type 5 (CCR5) antagonist, maraviroc, in rheumatoid arthritis (RA) patients with inadequate response to methotrexate, showing that it was ineffective. Two additional CCR5 antagonists, SCH351125 and AZD5672, also failed to demonstrate clinical efficacy. In addition, CCR5-blocking antibodies could not inhibit synovial fluid-induced monocyte chemotaxis. Thus, CCR5 appears not to be a desirable target in RA treatment. Given the multiple functions of CCR5, redundancies in the chemokine system, and patient selection in the trial, we overview the recent understanding for chemokine receptor blockade in the treatment of RA
弗莱沙克及其同事报告了一项关于 C-C 趋化因子受体 5(CCR5)拮抗剂马拉维若治疗对甲氨蝶呤反应不足的类风湿关节炎(RA)患者的双盲安慰剂对照临床试验,结果显示其无效。另外两种 CCR5 拮抗剂,SCH351125 和 AZD5672,也未能显示临床疗效。此外,CCR5 阻断抗体不能抑制滑液诱导的单核细胞趋化。因此,CCR5 似乎不是 RA 治疗的理想靶点。鉴于 CCR5 的多种功能、趋化因子系统的冗余性以及试验中的患者选择,我们综述了趋化因子受体阻断在 RA 治疗中的最新认识。
