Description
Vasoactive intestinal peptide (VIP) is a 28-amino-acid neuropeptide of the secretin/glucagon family, expressed throughout the nervous, immune and pulmonary systems. It is studied in smooth-muscle relaxation, immune-regulation and circadian research.
10 vials per box. Strengths are per vial; prices are per box.
Research summaries
VIP receptors and smooth-muscle tone
Physiology research characterizes VPAC1/VPAC2 receptor signalling in vasodilation, bronchodilation and gastrointestinal smooth-muscle relaxation, establishing VIP as a principal non-adrenergic non-cholinergic transmitter.
VIP is a native signalling molecule with established vasoactive physiology; its name describes that function directly.
Immunoregulatory activity of VIP
Immunology studies report VIP-mediated suppression of pro-inflammatory cytokines and promotion of regulatory T-cell responses, motivating research in inflammatory and autoimmune models.
VIP also suppresses inflammatory signalling, which extends its research use beyond vascular physiology.
