Overview
Vasoactive Intestinal Peptide is a 28-residue basic neuropeptide of the secretin/glucagon superfamily, studied as a VPAC1/VPAC2 receptor agonist in laboratory models of vascular, immune and neuroendocrine signaling.
History
Isolated from porcine intestine by Said and Mutt in 1970 and later shown to be widely distributed in neural tissue, VIP became a reference ligand for the VPAC receptor family and a common subject of anti-inflammatory signaling research.
