Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide belonging to the glucagon/secretin superfamily. Widely distributed throughout the nervous and immune systems, VIP acts on VPAC1 and VPAC2 receptors to mediate vasodilation, immunomodulation, and circadian rhythm entrainment. Its pleiotropic activity across the gastrointestinal, pulmonary, and central nervous systems has positioned it as a compound of considerable translational research interest.

Mechanisms of Research Interest

VIP binds VPAC1 and VPAC2 receptors, activating adenylyl cyclase and elevating intracellular cAMP to produce smooth muscle relaxation, vasodilation, and immunomodulatory effects. It promotes anti-inflammatory cytokine profiles — notably IL-10 and TGF-β — while suppressing pro-inflammatory mediators such as TNF-α and IL-6. Neuroprotective effects have been observed in CNS inflammation models, and VIP has been identified as a key regulator of the suprachiasmatic nucleus circadian clock.

Research Applications

VIP 10mg supports research into pulmonary hypertension, autoimmune and neuroinflammatory disease models, circadian biology, gastrointestinal motility, and bronchodilation pharmacology. Its dual role as a neuropeptide and immunomodulator makes it broadly applicable across disciplines ranging from immunology to chronobiology.
