Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide endogenous to the human nervous and immune systems. It is widely investigated for its broad physiological roles, acting primarily through VPAC1 and VPAC2 receptors to exert vasodilatory, bronchodilatory, and cytoprotective effects. VIP signals via cyclic AMP (cAMP) pathways, modulating smooth muscle relaxation, glandular secretion, and immune cell activity.
In preclinical research, VIP has demonstrated significant interest across several fields. It is studied for its anti-inflammatory and immunosuppressive actions, with potential relevance to autoimmune conditions, inflammatory bowel disease, and pulmonary hypertension. Research has also explored its neuroprotective properties, its role in circadian rhythm regulation, and its influence on gastrointestinal motility and secretion. Emerging studies have examined VIP’s potential in cardiovascular and respiratory research models.
