title: Inhibitory effect of galanin on pancreatic polypeptide release by the perfused rat pancreas.
abstract: We have investigated the effect of galanin infusion on unstimulated pancreatic polypeptide (PP) release as well as on the PP response to arginine by the perfused rat pancreas. Galanin significantly reduced unstimulated PP output. Addition of arginine to the perfusate evoked a biphasic pattern of PP release; the second phase of this PP response was delayed when galanin was simultaneously infused. These findings point to a regulatory role of galanin in the control of PP secretion.
