IL-17 is a cytokine produced by CD4 T cells that activates the production of inflammatory mediators by synoviocytes. To study the contribution of soluble factors in the interaction between T cells and synoviocytes in rheumatoid arthritis (RA), we looked at the effect of IL-17 on these cells in the presence of cytokines classified as pro (IL-1)- and(More)
IL-17 is defined as a proinflammatory cytokine and produced by activated CD4+ T cells. In rheumatoid arthritis synovial tissue, high levels of IL-17 contribute to IL-6 production by synoviocytes. The present study was performed to see whether Th cells that produce IL-17 are associated with the Th1, Th2, or Th0 subset. Thirty-three CD4+, alphabeta+ T cell(More)
The origin and role of IL-17, a T-cell derived cytokine, in cartilage and bone destruction during rheumatoid arthritis (RA) remain to be clarified. In human ex vivo models, addition of IL-17 enhanced IL-6 production and collagen destruction, and inhibited collagen synthesis by RA synovium explants. On mouse cartilage, IL-17 enhanced cartilage proteoglycan(More)
