VIP (Vasoactive Intestinal Peptide)
(Neuropeptide – Neuroimmune & Vasoregulatory Signaling Modulator)
Vasoactive Intestinal Peptide (VIP) is a naturally occurring neuropeptide composed of 28 amino acids and widely distributed throughout the central and peripheral nervous systems. It functions as an important signaling molecule involved in vasodilation, immune modulation, and neuroendocrine regulation.
VIP exerts its biological effects primarily through activation of G-protein–coupled receptors, including the VPAC1 Receptor and VPAC2 Receptor. These receptors are expressed in numerous tissues, including the brain, lungs, gastrointestinal tract, and immune cells.
In experimental research, VIP has been investigated for its potential role in regulating inflammatory signaling, vascular tone, and communication between the nervous and immune systems.
Mechanism of Action
(Based on Established Biological and Preclinical Research)
VPAC receptor activation:
VIP binds to VPAC1 and VPAC2 receptors, initiating intracellular signaling pathways mediated by cyclic AMP (cAMP).
Vasodilation signaling:
Research indicates VIP promotes relaxation of vascular smooth muscle, contributing to regulation of blood vessel diameter and blood flow.
Neuroimmune modulation:
Experimental studies suggest VIP regulates immune cell signaling and may reduce production of pro-inflammatory cytokines.
Neurotransmitter and neuroendocrine signaling:
VIP participates in communication between neurons and endocrine cells, influencing hormonal release and neural activity.
Gastrointestinal regulatory activity:
Investigations have explored VIP’s role in regulating intestinal motility, secretion, and smooth muscle function.
