| Abstract | Accumulating evidence suggested that glial cells are involved in synaptic plasticity and behavioral changes induced by drugs abuse. The role of these cells in maintenance and reinstatement of morphine (MRP) conditioned place preference (CPP) remains poorly characterized. The aim of present study was to investigate the direct role of glial cells in nucleus accumbens (NAc) in the maintenance and reinstatement of MRP-seeking behavior. CPP induced with injection of MRP (5 mg/kg, s.c. for 3 days), lasted for 7 days after cessation of MRP treatment and priming dose of MRP (1 mg/kg, s.c.) reinstated the extinguished MRP-induced CPP. The astrocyte-conditioned medium (ACM) and neuroglia conditioned medium (NCM) exposed to MRP (10 and 100 µM) have been microinjected into the NAc. Intra-NAc administration of ACM during extinction period failed to change the maintenance of MRP-CPP, but MRP 100-treated ACM could slightly increase the magnitude of reinstatement. In contrast to ACM, intra-NAc administration of MRP 100-treated NCM caused slower extinction by 3 days and significantly increased the magnitude of reinstatement. Our findings suggest the involvement of glial cells activation in the maintenance and reinstatement of MRP-seeking behaviors, and provides new evidence that these cells might be a potential target for the treatment of MRP addiction. |

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.
