Abstract

Calcitonin gene-related peptide (CGRP) is a 37 amino acid peptide recently demonstrated to be a peptide expressed by the calcitonin gene in the rat central nervous system. Intracerebroventricular administration of CGRP in pylorus ligated rats resulted in a dose dependent suppression of gastric acid secretion. This effect was also present in acutely vagotomized rats. In addition, CGRP inhibited the stimulation of gastric acid secretion by thyrotropin releasing hormone. CGRP was considerably less potent in its effect on gastric acid than calcitonin, a well known central inhibitor of gastric acid secretion in the rat. This study suggests that CGRP may be a factor in the central regulation of gastric acid secretion in the rat.
