Evidence that Intestinal Glucagon-Like Peptide-1 Plays a Physiological Role in Satiety

Abstract

A physiological role in satiety is proposed for glucagon-like peptide-1 (GLP-1), secreted by the distal intestine in response to ingested nutrients. Here we report that in rats, ip injection of the GLP-1 receptor (GLP-1-R) antagonist exendin 9-39 (Ex9) elicited hyperphagia, but only at times of day when intake is otherwise low. Furthermore, ip administration of Ex9 attenuated satiety induced by either a voluntarily consumed sucrose meal (by 100%) or an intragastric glucose load (by 40%). To determine whether these effects involve blockade of GLP-1-R in brain or at a peripheral site, we injected Ex9 either centrally (into the third ventricle) or peripherally (ip) prior to GLP-1 injected either centrally or peripherally. Anorexia induced by peripheral GLP-1 was fully blocked by peripheral, but not central, pretreatment with Ex9, whereas the opposite was true for anorexic effect of central GLP-1. Thus, ip Ex9 appears to attenuate satiety via peripheral GLP-1-R blockade. Finally, anorexia induced by ip injection of exendin-4 (a GLP-1-R agonist) was due to both reduced meal size and increased duration between meals. We conclude that GLP-1 released from the intestine in response to ingested nutrients is a physiologically active satiety signal.

  • Leptin reduces food intake by enhancing the CNS response to gut-derived satiety peptides such as cholecystokinin (CCK) and glucagon-like-peptide-1 (GLP-1).

    “One mechanism proposed to explain how leptin reduces food intake is by enhancing the CNS response to gut-derived satiety peptides, such as cholecystokinin (CCK) and glucagon-like-peptide-1 (GLP-1) (196)”

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.
