VIP is a shortened peptide derived from vasoactive intestinal peptide (VIP), a 28-amino-acid neuropeptide involved in smooth muscle relaxation, vasodilatory signalling, and immunomodulatory pathways. Fragmented VIP analogues are studied to explore whether shorter sequences can retain receptor activity with altered stability or selectivity profiles.

Fragmented VIP analogues are studied to explore whether shorter sequences can retain receptor activity with altered stability or selectivity profiles.
In experimental literature, VIP-derived peptides are examined for effects on VPAC receptor signalling, cyclic AMP (cAMP) pathways, and downstream modulation of inflammatory mediator release. Research often focuses on receptor-binding characteristics, signalling potency, and functional readouts such as vascular tone markers or immune-cell signalling changes in controlled models.
