Several studies have suggested that chemokine receptors are important mediators of inflammatory response in rheumatoid arthritis (RA). B cells are also known to play an important role in RA pathology. C-X-C chemokine receptor type 3 (CXCR3) is considered a potential therapeutic target in different inflammatory diseases; however, the mechanism remains unclear. Here, we evaluated the potentially protective effect of AMG487, a selective CXCR3 antagonist, in collagen-induced arthritis (CIA) mouse model. CIA mice were treated with AMG487 (5 mg/kg) every 48 h, from day 21 until day 41. We then investigated the effect of AMG487 on NF-κB p65-, NOS2-, MCP-1-, TNF-α-, IFN-γ, IL-4-, and IL-27-producing CD19 Show less
