Research Applications

Research use: VIP (vasoactive intestinal peptide) is studied as a potent vasodilatory neuropeptide acting through VPAC1/VPAC2 receptors.
Used in neuroprotection research to investigate its anti-inflammatory and anti-apoptotic effects on neuronal and glial cells.
Applied in autoimmune and inflammatory disease models (e.g., RA, SLE) to study VIPergic modulation of immune responses.
Serves as a tool for studying neurogenic vasodilation, circadian regulation, and gut-brain peptide signaling.
