Effects of galantamine on social interaction impairments in cholecystokinin receptor-2 overexpression mice.

We examined whether galantamine (GAL), a cholinesterase inhibitor and allosteric potentiating ligand for α7 nicotinic acetylcholine receptor (nAChR), had an impact on emotional abnormalities in forebrain-specific cholecystokinin receptor-2 overexpressed transgenic mice. Treatment with GAL (1 mg/kg, s.c.
