Antagonist Comments
PG99-465 has been used as a selective VPAC2 receptor antagonist in a number of physiological studies, but it may not be completely selective for this receptor subtype. A small molecule antagonist of human (but not mouse) VPAC2 receptors has been described, but has not yet been extensively characterised [4].
Immunopharmacology Comments
Monocytes from Sjögren's syndrome patients display increased VPAC2 receptor expression and impaired apoptotic cell phagocytosis [21]. The potential role of the VIP-PACAP system in immunity is reviewed in [11].

VPAC2 receptor-deficient mice showed retarded growth and had reduced serum IGF-I levels. Older male mutant mice exhibited diffuse seminiferous tubular degeneration with hypospermia and reduced fertility rate. The mutant mice appeared to have an increase in insulin sensitivity, increased lean mass and decreased fat mass with reduced serum leptin levels. Additionally, VPAC2 receptor-deficient mice had an increased basal metabolic rate.

Technique:  Gene targeting in embryonic stem cells.
References:  2
Transgenic mice overexpressing the human VPAC2 receptor from a yeast artificial chromosome construct resynchronized more quickly than wild-type controls to an advance of 8 h in the light-dark cycle and exhibited a significantly shorter circadian period in constant darkness, suggesting that the VPAC2 receptor can influence the rhythmicity and photic entrainment of the circadian clock.
Species:  Mouse
Tissue: 
Technique:  Transgenesis.
References:  37
Constitutive expression of the VPAC2 receptor selectively in CD4+ T cells (helper-inducer Th cells) in transgenic mice resulted in production of more Th2-type and less Th1-type cytokines after TCR activation, thus evoking an allergic state in normally nonallergic mice.
Species:  Mouse
Tissue: 
Technique:  Transgenesis.
References:  44-45
VPAC2 receptor null mice have normal basic immune characteristics, but display significantly enhanced delayed-type hypersensitivity and reduced immediate-type hypersensitivity, consistent with a role for the receptor in the maintenance of the normal ratio of Th2/Th1 cytokines.

References:  48
VPAC2 receptor null mice exhibit a loss of normal circadian rhythms of electrical activity and clock gene expression in the suprachiasmatic nucleus (SCN). Consequently, rhythms of physiology (heart rate, blood pressure, body temperature and metabolic rate) and behaviour (activity, sleep/wake and feeding) are lost when animals are placed under constant conditions. When kept in a light/dark cycle, ryhtms of physiology and behaviour are phase advanced compared to wild-type mice. VIP null mice display a similar circadian phenotype, suggesting that VIP functions as the endogenous ligand of the VPAC2 receptor in the control of circadian rhythms in the SCN.

Clinically-Relevant Mutations and Pathophysiology
Disease:  Schizophrenia 16; SCZD16
Synonyms: Schizophrenia [Orphanet: ORPHA3140] [OMIM: 181500] [Disease Ontology: DOID:5419]
Disease Ontology: DOID:5419
OMIM: 181500, 613959
Orphanet: ORPHA3140
Comments:  Two groups have shown that copy number variation leading to duplications of the VIPR2 gene confers significant risk for schizophrenia.
References:  25,43
Biologically Significant Variants
Type:  Splice variants.
Species:  Mouse
Description:  A deletion variant of mouse VPAC2 has been identified in immune cells that lacks amino acids 367-380 at the carboxyl-terminal end of the seventh transmembrane domain. The variant did not transduce VIP-elicited increases in intracellular concentration of cyclic AMP, chemotaxis, or suppression of generation of interleukin-2, without apparent alterations of expression or ligand binding.
