VIP (Vasoactive Intestinal Peptide)

VIP — Vasoactive Intestinal Peptide (28-AA Neuropeptide)
ImmuneFDA: Not approved as standalone...

Overview

Shoemaker CIRS Protocol: final step for mold/biotoxin-related Chronic Inflammatory Response Syndrome — corrects TGF-β1, C4a, MMP9 refractory to other therapies. Autoimmune, COPD, pulmonary hypertension, IBD research. Endogenous neuropeptide with FDA-approved analogs.

Mechanism of Action

28-AA linear neuropeptide; C-terminal amidation for stability. Sequence: His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn-NH2. Binds VPAC1 and VPAC2 receptors (Gαs) → adenylate cyclase → cAMP/PKA. Anti-inflammatory: inhibits TNF-α, IL-6, IL-1β. Modulates Th1/Th2/Th17/Treg balance. Intranasal: olfactory/trigeminal pathway for direct brain access.
