| Abstract | Mood disorder patients that are on long-term atypical antipsychotics treatment frequently experience metabolic dysfunctions. In addition to this, accumulating evidences points to increased risk of structural abnormalities, brain volume changes, altered neuroplasticity and behavioral depression with long-term antipsychotics use. However, there is paucity of preclinical evidences for long-term antipsychotic associated depression-like behavior. The objectives of the present study were: (1) to evaluate influence of long-term antipsychotic (olanzapine) treatment on rat behavior in forced swim test (FST) as a model for depression and; (2) to examine impact of glucagon-like peptide 1 (GLP-1) receptor agonist liraglutide - an antidiabetic medication for type II diabetes, on long-term olanzapine associated metabolic and behavioral changes in rats. Daily olanzapine treatment (0.5 mg/kg; p.o.) for 8-9 weeks significantly increased body weights, food and water intake, plasma cholesterol and triglycerides and immobility time in FST with parallel reduction in plasma HDL cholesterol levels. These results points to development of metabolic abnormalities and depression-like behavior with long-term olanzapine treatment. Acute liraglutide (50 μg/kg; i.p.) and imipramine (10 mg/kg, i. p.) treatment per se significantly decreased duration of immobility in FST compared to vehicle treated rats. Additionally, 3-week liraglutide treatment (50 μg/kg; i.p., daily) partially reversed metabolic abnormalities and depression-like behavior with long-term olanzapine-treatment in rats. None of these treatment regimens affected locomotor behavior of rats. In summary, add-on GLP-1 receptor agonists promise novel alternatives to counteract long-term antipsychotics associated behavioral and metabolic complications. |

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.
