Overview

VIP is a 28-amino-acid neuropeptide found in the nervous, endocrine, and immune systems. In research contexts, it is studied for signaling roles involving smooth muscle, secretion, circadian biology, and immune modulation.

Mechanism of Action

VIP signals primarily through VPAC1 and VPAC2 G protein-coupled receptors, increasing intracellular cAMP in responsive cells. These receptor pathways are used to study neuroimmune communication, vasoregulatory signaling, and peptide-mediated cellular responses.

Common Research Uses

Neuropeptide signaling research
VPAC receptor studies
Immune modulation research
Circadian pathway studies
