Pituitary adenylate cyclase-activating polypeptide (PACAP) stimulates melatonin release from pineal cells and modulates glutamatergic regulation of the suprachiasmatic circadian clock in rodents. We investigated whether PACAP is involved in melatonin release and the circadian oscillation system in chick pineal cells, and if so, whether its effects are mediated by the PACAP-specific receptor (PACAP-r1) or the vasoactive intestinal polypeptide (VIP) receptor. Chick pineal cells were maintained… CONTINUE READING
