Tas2r105 ameliorates gut inflammation, possibly through influencing the gut microbiota and metabolites.

ABSTRACT: Inflammatory bowel disease (IBD) is an immune-mediated gastrointestinal disorder that significantly impacts the life quality of people worldwide. Genetic factors play crucial roles in the development of IBD. Tas2rs, members of the G protein-coupled receptor (GPCR) superfamily, are known for their roles in bitter taste perception. However, Tas2rs have also been identified in the gut, where they help sense luminal contents and regulate gastrointestinal hormones. Periodontal Tas2r105 has been shown to modulate innate immunity by interacting with metabolites produced by oral bacteria. In this study, we observed increased Tas2r105 in the inflammatory colons induced by dextran sulfate sodium salt (DSS). We also noted that α-gustducin, the α-subunit of GPCRs, is present in the intestine, and that
