Pituitary adenylate cyclase-activating polypeptide (PACAP) is a ubiquitous neuropeptide of the vasoactive intestinal peptide. Brabet P. . PAC1 receptor-deficient mice display impaired insulinotropic response to glucose and reduced glucose tolerance. Brabet P. Philippe Brabet. We used individual level genotype data generated from 1, Brabet P. PAC1 receptor-deficient mice display impaired insulinotropic response to glucose and reduced glucose tolerance. J Clin Invest –, The purpose of this review is to present recent data on the effects of PACAP, VIP, VPAC1R, VPAC2R and PAC1R on the modulation of appetite.
