Brain delivery of vasoactive intestinal peptide (VIP) following nasal administration to rats [PDF]
, 2003 The aim of this work was to study in rats the nasal route for the brain delivery of the vasoactive intestinal peptide (VIP) neuropeptide. After evaluating VIP stability in solutions obtained from nasal washes, the effect of formulation parameters (pH 4-9,

Effect of Intraduodenal Bile and Taurodeoxycholate on Exocrine Pancreatic Secretion and on Plasma Levels of Vasoactive Intestinal Polypeptide and Somatostatin in Man [PDF]
, 1994 Intraduodenal (i.d.) application of bile or Na-taurodeoxycholate (TDC) dose dependently enhances basal exocrine pancreatic secretion. The hydrokinetic effect is mediated at least in part by secretin.

PACAP and its receptors in cranial arteries and mast cells
The Journal of Headache and Pain, 2018 Background In migraineurs pituitary adenylate cyclase activating peptide1–38 (PACAP1–38) is a potent migraine provoking substance and the accompanying long lasting flushing suggests degranulation of mast cells.

A distinctive ligand recognition mechanism by the human vasoactive intestinal polypeptide receptor 2
Nature Communications, 2022 Vasoactive intestinal polypeptide receptor 2 (VIP2R) is involved in immunity. Here, the authors report two cryo-EM structures of the VIP2R–Gs in complex with the endogenous peptide ligand PACAP27, revealing a unique interaction mode between PACAP27 and ...

Chronic alcohol consumption and withdrawal do not induce cell death in the suprachiasmatic nucleus, but lead to irreversible depression of peptide immunoreactivity and mRNA levels [PDF]
, 1997 There is evidence that chronic ethanol treatment (CET) disrupts the biological rhythms of various brain functions and behaviors. Because the suprachiasmatic nucleus (SCN) is widely recognized as the dominant pacemaker of the circadian system, we have ...

VIP treatment prevents embryo resorption by modulating efferocytosis and activation profile of maternal macrophages in the CBAxDBA resorption prone model [PDF]
, 2016 Successful embryo implantation occurs followed by a local pro-inflammatory response subsequently shifted toward a tolerogenic one. VIP (vasoactive intestinal peptide) has embryotrofic, anti-inflammatory and tolerogenic effects.

Effects of the vasoactive intestinal peptide (VIP) and related peptides on glioblastoma cell growth in vitro [PDF]
, 2003 The growth rate of numerous cancer cell lines is regulated in part by actions of neuropeptides of the vasoactive intestinal peptide (VIP) family, which also includes pituitary adenylate cyclase-activating peptide (PACAP), glucagon, and peptide histidine ...

Vasoactive intestinal peptide: cardiovascular effects [PDF]
Cardiovascular Research, 2001 Vasoactive intestinal peptide (VIP) is present in the peripheral and the central nervous systems where it functions as a nonadrenergic, noncholinergic neurotransmitter or neuromodulator. Significant concentrations of VIP are present in the gastrointestinal tract, heart, lungs, thyroid, kidney, urinary bladder, genital organs and the brain.
