Levels of ionotropic glutamate and muscarinic receptors in three animal models of schizophrenia

Abstract

There are well validated rodent paradigms of schizophrenia which are based on environmental manipulation (e.g. altered rearing conditions) or drug challenges. These manipulations induce behavioural changes in rodents that are thought to involve neuronal circuitry similar to the ones that are affected by the pathophysiology of the disorder. This study has investigated whether three such rodent paradigms (isolation rearing, neonatal PCP treatment or sub-chronic PCP treatment) are associated with changes in muscarinic receptors (CHRMs) or ionotropic glutamate receptors, some of which have been reported to be altered in the CNS of subjects with schizophrenia.
