VIP

VIP (Vasoactive Intestinal Peptide) is a naturally occurring 28–amino-acid neuropeptide of the secretin/glucagon peptide family.

Mechanism of action. In research models, VIP activates the VPAC1 and VPAC2 receptors, where it is studied for roles in vasodilation, smooth-muscle relaxation, immune and anti-inflammatory modulation, and circadian/neuroendocrine signaling.

Research applications. Used in immunology, neuroendocrine, and vascular research models.
