Cutting Edge: Intestinal IL-17A Receptor Signaling Specifically Regulates High-Fat Diet-Mediated, Microbiota-Driven Metabolic Disorders.

ABSTRACT: Previous studies indicate that IL-17A plays an important role in mediating the intestinal microbiota and systemic metabolic functions. However, it is not known where IL-17RA signaling occurs to mediate these effects. To investigate this question, we used intestinal epithelial-specific (Il17ra ^ΔIEC ) and liver-specific (Il17ra^ΔLiver ) IL-17RA knockout mice as well as littermate control mice. Our results indicate that intestinal IL-17RA signaling helps mediate systemic metabolic functions upon exposure to prolonged high-fat diet. Il17ra ^ΔIEC mice display impaired glucose metabolism, altered hormone and adipokine levels, increased visceral adiposity, and greater hepatic lipid deposition when compared with their littermate con
