Vasoactive Intestinal Peptide (VIP)
aka VIP
Mechanism
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide of the secretin/glucagon family, widely distributed in the CNS and peripheral nervous system. It is a potent vasodilator, bronchodilator, and immunomodulator. Synthetic VIP (aviptadil) has been investigated in clinical trials for COVID-19-associated acute respiratory failure; it is NOT FDA-approved. Intranasal compounded VIP is used off-label in the controversial 'CIRS' (Chronic Inflammatory Response Syndrome) / mold-illness protocol popularized by Ritchie Shoemaker — CIRS is not a mainstream medical diagnosis.

Research
Patients infected with SARS-CoV-2 may develop mild respiratory symptoms but also Acute Respiratory Distress Syndrome (ARDS). Additionally, severe systemic inflammation contributes to morbidity and mortality.

This is characterized by both gastrointestinal (GI) and extra-intestinal symptoms, which improve with the elimination of wheat intake.

source →Vasoactive intestinal peptide (VIP) is a neuropeptide that play an important role in immunoregulation and anti-inflammation. Numerous inflammatory/autoimmune disorders are associated with decreased VIP binding ability to receptors and diminished VIP activation of cAMP generation in immune cells.
