VPAC1 is a 52kD seven transmembrane G protein-coupled receptor which mediates VIP (vasoactive intestinal peptide) and PACAP (pituitary adenlyate cyclase activating peptide) function in a variety of tissues.
VIP is expressed and secreted by neurones innervating primary and secondary immune organs, and is involved in smooth muscle relaxation, exocrine and endocrine secretion, and water and ion flux in lung and intestinal epithelia.
VIP also has potent anti-proliferative and anti-inflammatory functions in the immune system, and VPAC1 is down-regulated under conditions of optimal T cell stimulation.
