Abstract Recent studies of the pathogenesis of rheumatoid arthritis RA have revealed that both synovial fibroblasts and T cells participate in the perpetuation of joint inflammation as dynamic partners in a mutual activation feedback via secretion of cytokines and chemokines that stimulate each other. In this study we investigated the role of IL-17 a major Th1 cytokine produced by activated T cells in the activation of RA synovial fibroblasts. Transcripts of IL-17R IL-17 receptor and IL-17RB IL-17 receptor B were present in fibroblast-like synoviocytes FLS of RA patients. IL-17R responded with increased expression upon in vitro stimulation with IL-17 while the level of IL-17RB did not change. IL-17 enhanced the production of IL-6 and IL-8 in FLS as previously shown but did not affect the synthesis of IL-15. IL-17 appears to be a stronger inducer of IL-6 and IL-8 than IL-15 and even exerted activation .
