Abstract
An adrenal pheochromocytoma cell line, PC12h, was found to respond to a novel hypothalamic neuropeptide, Pituitary Adenylate Cyclase Activating Polypeptide (PACAP). The cells elevated both intracellular and extracellular cAMP levels on stimulation by PACAP, whereas they showed little response to VIP which is structurally related to PACAP. Using [125I]PACAP27 (a shorter form of the peptide) and [125I]VIP, we found large amounts of specific binding sites for PACAP but few binding sites for VIP in PC12h cells. These results indicate that PC12h cells respond to PACAP via a specific PACAP receptor.Entities:
