Accumulating evidence from human genetic studies implicates the pituitary adenylate cyclase-activating polypeptide (PACAP) gene as a risk factor for psychiatric disorders, including schizophrenia and stress-related diseases.
In this study, we examined the effects of the selective metabotropic glutamate 2/3 (mGlu2/3) receptor agonist MGS0028 on behavioral abnormalities in mice lacking the pituitary adenylate cyclase-activating polypeptide (PACAP), an experimental model of psychiatric disorders such as schizophrenia and attention-deficit/hyperactivity disorder.
In this study, we examined whether inhibiting the 5-HT(7) receptor could reverse behavioral abnormalities in mice lacking pituitary adenylate cyclase-activating polypeptide (PACAP), an experimental mouse model for psychiatric disorders such as schizophrenia.
Mice lacking the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) (PACAP(-/-)) display behavioral abnormalities, and genetic variants of the genes encoding PACAP are associated with schizophrenia.
This study did not provide evidence for the contribution of the PACAP gene to the etiology of schizophrenia or bipolar disorders in the Japanese population.
We previously found that juvenile pituitary adenylate cyclase-activating polypeptide (PACAP)-knockout (PACAP(-/-)) mice reared in an enriched environment (EE) for 4 weeks showed attenuated hyperactivity, jumping behavior, impairments in social interaction, and depression-like behavior.

The behavioral phenotype of pituitary adenylate-cyclase activating polypeptide-deficient mice in anxiety and depression tests is accompanied by blunted c-Fos expression in the bed nucleus of the stria terminalis, central projecting Edinger-Westphal nucleus, ventral lateral septum, and dorsal raphe nucleus.
