Short-Chain Fatty Acid Receptor and Its Contribution to Glucagon-Like Peptide-1 Release

Abstract

Background: Gut microbiota affects host homeostasis and dysbiosis causes host diseases. Therefore, uncovering the sensing mechanism of bacterial metabolites such as short-chain fatty acid (SCFA) may help us to understand the host-microbiota interaction both in physiological and nonphysiological conditions. Summary: The colonic lumen is continually exposed to many kinds of chemicals, including beneficial and harmful compounds that are produced by gut microbiota in addition to ingested nutrients. In the mammalian colon SCFAs such as acetate, propionate and butyrate are produced by bacterial fermentation and reach about 100 mM under physiological conditions. In this decade, SCFA receptor genes and their expression in the intestine have been identified as free fatty acid receptor (FFA)2 and FFA3. The FFAs are located in colonic enteroendocrine L cells producing and releasing an insulinotropic hormone, glucagon-like peptide-1 (GLP-1), and an anorectic hormone, peptide YY. Recent in vivo and in vitro studies suggest that SCFAs stimulate gut hormone secretion. Therefore, the SCFA-FFA signal is likely to be important for gut physiological functions. Key Message: Colonic epithelial cells express chemical receptors that detect the luminal contents, particularly bacterial metabolites, and may be involved in the host's energy metabolism via GLP-1 release, as well as the mucosal defense system.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
