Description
Vasoactive intestinal peptide is a 28-residue neuropeptide from the secretin/glucagon family, found across nervous, immune and lung tissue. Researchers study it for smooth-muscle relaxation, immune regulation and circadian timing.
Supplied by LiliPeptide in boxes of 10 vials, priced per box. The strength shown is the amount in each vial.
Research notes
VPAC receptors and smooth muscle
Physiology research has mapped how VIP signals through VPAC1 and VPAC2 receptors to widen blood vessels and airways and to relax gut smooth muscle, making it a principal non-adrenergic, non-cholinergic transmitter.
Immune regulation
Immunology studies report that VIP dampens pro-inflammatory cytokines and supports regulatory T-cell responses, which has led to research in inflammatory and autoimmune models.
