Vasoactive Intestinal Peptide (VIP) is a naturally occurring neuropeptide composed of 28 amino acids that is widely studied for its role in cellular signaling, vasodilation, and neuro-immune regulation. In laboratory and experimental models, VIP interacts primarily with VPAC1 and VPAC2 receptors, influencing pathways associated with smooth muscle relaxation, inflammatory modulation, and neurotransmission. Because of its involvement in multiple physiological signaling systems, VIP is frequently utilized in research exploring neuroendocrine communication, immune responses, and vascular regulation.
