Glucagon-Like Peptide-1 7-36 Amide and Peptide YY from the L-Cell of the Ileal Mucosa Are Potent Inhibitors of Vagally Induced Gastric Acid Secretion in Man

Abstract

GLP-1 and PYY are both potent inhibitors of the cephalic phase of acid secretion, indicating that at least part of the inhibitory effect of GLP-1 and PYY in man is mediated through neural pathways. Furthermore, the inhibitory effect seems to be independent of circulating concentrations of gastrin and somatostatin.
