Effect of calcitonin gene-related peptide (CGRP) on somatostatin release was investigated on the isolated perfused rat stomach. Perfusion with CGRP (0.1 nM-100 nM) caused a significant and dose-dependent increase in effluent somatostatin levels. The somatostatin response to CGRP was rapid in onset and reversible immediately after the cessation of CGRP infusion. These findings suggest that CGRP stimulates the release of gastric somatostatin, thereby modulating gastric functions in rat.
