Outline of Final Research Achievements |
To compare the roles of Th1, Th2, and Th17 cytokines, we applied bleomycin-induced scleroderma model to mice deficient for interferon (IFN)-γ, interleukin (IL) -4, and IL-17A. The loss of IL-17A significantly attenuated bleomycin-induced skin fibrosis, whereas deficiency of IFN-γ or IL-4 did not. The leukocyte infiltration and mRNA expression levels of TGF-β and CTGF in the bleomycin-injected skin were significantly reduced in IL-17A-deficient mice. Bleomycin injection stimulated the differentiation of naive T cells into Th17 cells and increased IL-17 expression in the skin. Cell lines of skin fibroblasts expressed increased TGF-β, CTGF, and collagen by the addition of IL-17A. IL-17A, a representative Th17 cytokine, plays a dominant role during the development of skin fibrosis. That is, bleomycin injection induces IL-17A production and increased IL-17A likely stimulates collagen production from fibroblasts probably via cytokine production such as TGF-β and CTGF in mice.
