Brabet P. 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. PAC1 receptor-deficient mice display impaired insulinotropic response to glucose and reduced glucose tolerance. In this study, we performed biological pathway-based GWA analysis for BMI and body fat mass. PAC1 receptor-deficient mice display impaired insulinotropic response to glucose and reduced glucose tolerance. Pituitary adenylate cyclase-activating polypeptide (PACAP) is a ubiquitous neuropeptide of the vasoactive intestinal peptide.
