Glucagon-Like Peptide-2 Inhibits Centrally Induced Antral Motility in Pigs

Pages 828-832 | Published online: 08 Jul 2009
 

Abstract

Background: Glucagon-like peptide-2 is formed from proglucagon in the intestinal L-cells and is secreted postprandially in parallel with the insulinotropic hormone GLP-1 (glucagon-like peptide-1), which in addition acts to inhibit gastric motility (enterogastrone effect) by inhibiting central parasympathetic outflow. GLP-2 has no effect on the endocrine pancreas. We here tested the hypothesis that GLP-2 acts as an enterogastrone. Methods: Fourteen anesthetized pigs with their splanchnic nerves cut were subjected to insulin hypoglycemia, and force transducers were sutured to the antrum to record motility. GLP-2 was infused intravenously in doses from 1 to 6 pmol/kg/min after the onset of antral motility in response to hypoglycemia. Results
