VIP is a small signaling peptide the body makes naturally in nerves and immune cells. It helps widen blood vessels, release fluid from glands, and adjust immune-cell activity through two receptors, VPAC1 and VPAC2. Because this signaling system touches the gut, circulation and inflammation, researchers use VIP as a laboratory tool. The studies collected here are an immune review and preclinical experiments in gut cells and mice after radiation injury. They describe mechanisms and model-specific findings, not human treatment results. They do not show whether any particular supplied material is pure, correctly identified or active.
Shared values below are consolidated from the current catalog record. They are not independent verification or lot results; request the applicable product specification and ask which lot records are available before ordering.

Reported research findings
Reported outcomes are paired with their experimental model and evidence boundary.
A review summarized VIP effects across innate and adaptive immune-cell pathways.
A mechanistic review does not establish efficacy for a supplied peptide material.
Read the primary studyA 2024 study reported secretory-differentiation and injury outcomes in radiation-exposed intestinal models.

Concise answers for researchers comparing identity, evidence and catalog variants.
Two directions stand out. A review maps VIP as a wide-ranging immune regulator acting through VPAC receptors and cAMP. A preclinical study found VIP nudged intestinal cells toward a secretory fate, altered progenitor-cell division, and lessened radiation injury in organoids and in mice given abdominal radiation. These describe mechanism and model outcomes, not confirmed benefits for people. Neither finding speaks to the quality, purity or performance of any particular catalog material.
Published biology and animal studies say nothing about the purity, identity or handling of a commercial research vial. A catalog listing, a purity report and a biological finding answer three different questions. Existing product documents control identity and lot release. The reference studies control statements about mechanism and model-specific outcomes. Keeping these layers apart is why this page reports both the promising preclinical recovery findings and the plain fact that human therapeutic evidence is not supplied here.
The evidence base is broad in physiology but therapeutic intervention evidence remains indication-specific and frequently preclinical.
No. The cited records describe their own intervention, formulation, model and controls. They do not verify the identity, purity, sterility, safety or efficacy of a catalog lot.
A lot-specific COA, product specification sheet and analytical method summary can be requested where applicable.
Store at -20 °C, protected from light and moisture. After reconstitution, aliquot and avoid repeated freeze-thaw cycles. Confirm the applicable storage statement on the product-specific specification and lot documentation.
