Perinatal phencyclidine (PCP) treatment leads to neuronal damage and causes long-term behavioural alterations in rodents. This study examined the effects of perinatal PCP treatment on behaviour of adult rats in holeboard, elevated plus maze, social interaction and forced swim tests. PCP-treated rats displayed hyperactivity in the holeboard and forced swim tests. These persistent behavioural changes are relevant to the study of psychiatric disorders such as schizophrenia.

Schizophrenia is a complex and devastating mental disorder of unknown etiology. Hypofunction of N-methyl-d-aspartate (NMDA) receptors are implicated in the disorder, since phencyclidine (PCP) and other NMDA receptor antagonists mimic schizophrenia-like symptoms in humans and animals so well. Moreover, genetic linkage and post mortem studies strongly suggest a role for altered neuregulin 1 (Nrg1)/erbB4 signaling in schizophrenia pathology. This study investigated the relationship between the NMDA receptor and Nrg1 signaling pathways using the perinatal PCP animal model. Rats (n = 5/group) were treated with PCP (10 mg/kg) or saline on postnatal days (PN) 7, 9 and 11 and were sacrificed …

N-methyl-d-aspartate (NMDA) receptor blockade in rodents induces behavioural and neurochemical changes reminiscent of schizophrenia symptoms and pathology. To examine how NMDA receptor blockade affects glutamatergic and GABAergic pathways when administered during early brain development, [3H]MK-801 and [3H]muscimol binding to NMDA and GABAA receptors was examined at four time-points following injections of phencyclidine (PCP) or saline on postnatal days (PN)7, 9 and 11. [3H]MK-801 binding was significantly increased in PCP-treated rats in the thalamus from PN18 to PN96, in the prefrontal and anterior cingulate cortices at PN32, and in the hippocampus at PN96. In a similar manner, [3H]muscimol binding was increased …

Perinatal phencyclidine (PCP) treatment has been used to model brain pathological processes that may be present in schizophrenia such as increased apoptosis during early brain development, and long-term alterations in expression of parvalbumin-containing interneurons and glutamatergic N-methyl-d-aspartate (NMDA) receptors. We report that this treatment also affects receptor expression of another excitatory neurotransmitter receptor, the muscarinic receptor. Female rat pups received injections of the NMDA receptor antagonist PCP (10 mg/kg, s.c.) or saline on postnatal days (PN)7, 9 and 11. [3H]Pirenzepine binding to M1/4 receptors was examined at four time-points (PN12, 18, 32 and 96) following treatment cessation. Significant effects of …
