Title	CCL20-CCR6 signaling alters the metabolic reprogramming to promote the pathogenic Th17 cell differentiation
Description	Chemokine receptor CCR6 is a G-protein-coupled receptor that binds its high-affinity ligand, CCL20. Among the CD4+ T cells, Th17 and regulatory T cells express CCR6, which facilitates their migration in CCL20-enriched, inflamed tissue. Migration of CCR6+ T cells from secondary lymphoid tissues into inflamed tissues exposes them to a distinct metabolic microenvironment. What drives the metabolic adaptation of cells in these tissues and what contributes to their effector or regulatory function is not clearly understood. During colitis, increased gut production of CCL20 promotes the recruitment of these cells. We demonstrated that the intrinsic signaling of CCL20-CCR6 in CD4+ T cells promotes the differentiation of inflamatory Th1-like Th17 cells (T-bet+RORγt+) during colitis in both mouse models and humans. This signaling induces rapamycin-sensitive phosphorylation of PI3K, Akt, mTORC1, and STAT3 in a CCR6-dependent manner. RNA-seq and proteomics analysis revealed alterations in CCL20 during Th17 differentiation, affecting several metabolic pathways, including energy metabolism. CCL20 significantly increased glycolysis and inhibited oxidative phosphorylation, thereby driving the differentiation of pathogenic Th17 cells. Our findings suggest that alterations in CCR6-induced changes in Th17 metabolism offer an interesting therapeutic target for gut inflammation and autoimmunity.
