VIP (Vasoactive Intestinal Peptide)

Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide widely distributed in the central and peripheral nervous systems. It functions as a potent vasodilator, immune modulator, and neurotransmitter. Research applications span pulmonary hypertension, inflammatory conditions, circadian rhythm regulation, and neuroprotection.
