| Research Abstract |
Although interleukin-17 (IL-17)-producing T cells were reported to play pathogenic roles in murine autoimmune disease models, there are few information about it in human autoimmune diseases. One of the aims of this study was to analyze which are the predominant cells, IL-17 producing T cells or IFN-gamma producing T cells in murine arthritis models as well as rheumatoid arthritis.
IL-17 producing T cells were predominant population in both collagen-induced arthritis (CIA) in mice and SKG mice in affected joints. In CIA mice, the majority of IL-17 producing T cells were not alpha/beta T cells but gamma/delta T cells, in contrast, IL-17 producing T cells were not gamma/delta T cells but alpha/beta T cells in affected joints of SKG mice. Furthermore, IFN-gamma producing T cells were predominant in the joints of RA. These results demonstrate that there were significant differences in the cytokine profile of T cells in the arthritic joints of two murine models and human RA.
