Pituitary adenylate cyclase activating peptide (PACAP) is a peptide that is present in the hypothalamus and other areas of the rat brain. This study demonstrates that PACAP reduces food intake after intracerebroventricular injection in food-deprived mice. Behavioral analysis suggests that this decrease in food intake is, in part, compensated for by an increase in other behaviors. Pituitary adenylate cyclase activating peptide also was demonstrated to antagonize increased food intake resulting from administration of neuropeptide Y. Thus, PACAP joins a growing list of neuropeptides involved in the central regulation of food intake.

D009478	Neuropeptide Y	A 36-amino acid peptide present in many organs and in many sympathetic noradrenergic neurons. It has vasoconstrictor and natriuretic activity and regulates local blood flow, glandular secretion, and smooth muscle activity. The peptide also stimulates feeding and drinking behavior and influences secretion of pituitary hormones.

Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D051219	Pituitary Adenylate Cyclase-Activating Polypeptide	A multi-function neuropeptide that acts throughout the body by elevating intracellular cyclic AMP level via its interaction with PACAP RECEPTORS and VASOACTIVE INTESTINAL PEPTIDE RECEPTOR. Although first isolated from hypothalamic extracts and named for its action on the pituitary, it is widely distributed in the central and peripheral nervous systems. PACAP is important in the control of endocrine and homeostatic processes, such as secretion of pituitary and gut hormones and food intake.
