| Abstract | 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 treatment on [3H]pirenzepine binding were evident immediately after treatment cessation with a decrease in PCP-treated rats at PN12 in the prefrontal cortex (-24%, p<0.05) and hippocampus (-19%, p<0.05). After this initial decrease, binding subsequently increased to 47% above control levels in the prefrontal cortex of adolescent animals, which remained elevated in adulthood (+10%, p<0.05), while in the hippocampus there was a trend towards increased binding in adolescent animals and no change thereafter. This work adds to findings demonstrating that perinatal PCP exposure leads to long-term imbalance of excitatory and inhibitory neurotransmitter systems, supporting its relevance as a developmental model of schizophrenia pathology. Alterations in muscarinic receptor expression may contribute specifically to the cognitive impairments reported to occur after perinatal NMDA receptor antagonist treatment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
