Fenofibrate represses interleukin-17 and interferon-gamma expression and improves colitis in interleukin-10-deficient mice.
Interleukin-10 knockout (IL-10(-/-)) mice spontaneously develop colitis characterized by T-helper cell type 1-polarized inflammation. We tested the possible therapeutic activity of the peroxisome proliferator-activated receptor alpha (PPARalpha) ligand fenofibrate, and the PPARdelta ligand GW0742, in IL-10(-/-) mice and investigated the cellular/molecular mechanisms for fenofibrate action.. The effect of fenofibrate or GW0742 on the progression of colitis in C3H.IL-10(-/-) mice was evaluated. Effects of fenofibrate on cytokine and chemokine gene expression were studied in cultured splenocytes, pathogenic T cells isolated from C3H/HeJBir mice, and HT-29 colorectal cancer cells.. Treatment of C3H.IL-10(-/-) mice with fenofibrate delayed the onset of colitis, decreased the colonic histopathology score, and decreased colonic expression of genes encoding the inflammatory cytokines interferon-gamma and interleukin (IL)-17. The target for fenofibrate, PPARalpha, was expressed in lymphocytes, macrophages, and crypt and surface epithelial cells of the colon. The mean number of lymphocytes was decreased by more than 75% in colonic sections of fenofibrate-treated as compared with control IL-10(-/-) mice, and fenofibrate repressed interferon-gamma and IL-17 expression in isolated T cells. Fenofibrate also repressed the expression of the genes encoding 3 chemokines, CXCL10, CCL2, and CCL20, and repressed CXCL10 gene promoter activity in tumor necrosis factor-alpha-treated HT-29 cells. In contrast to the beneficial effect of fenofibrate, the PPARdelta ligand GW0742 accelerated the onset of colitis in IL-10(-/-) mice.. The immunopathology observed in IL-10(-/-) mice resembles that seen in Crohn's disease. The novel therapeutic activity of fenofibrate in this mouse model suggests that it may also have activity in Crohn's disease.
