NOX1 and colitis: Notably, Akkermansia muciniphila stimulates the proliferation and migration of enterocytes adjacent to the colonic wounds, through FPR1 (formyl peptide receptor 1) and NOX1 (NADPH Oxidase 1)-mediated redox signaling in epithelial cells, thus enhancing the repair of mucosal wounds and protecting mice from chemically induced colitis (79).
