| Abstract | BDNF is strongly implicated in the development of depression. Recent evidence has indicated that tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) are related to the cleavage of pro-brain-derived neurotrophic factor (BDNF) into its mature form. Chronic unpredicted mild stress (CUMS) is widely used to induce depressive behaviors in rodents. Therefore, we investigated the effects of PUFAs and sertraline on tPA/PAI-1 system in CUMS rats. After 5 weeks of CUMS procedures, the rats were induced to a depressive-like state. The expressions of PAI-1 and proBDNF were increased in the prefrontal cortex and hippocampus of CUMS rats. N-3 polyunsaturated fatty acids (PUFAs) or sertraline administration reversed the changes in behavioral test and induced the expression of tPA in certain brain areas, but failed to restore the CUMS-induced PAI-1 expression. Meanwhile, the antidepressant treatment also accelerated the extracellular conversion of proBDNF into mature BDNF in CUMS rats. Our results firstly showed the synchronously altered balance of tPA/PAI-1 system in the prefrontal cortex and hippocampus of CUMS rats, which was partly ameliorated by PUFAs and sertraline medication, providing new evidence for the involvement of tPA/PAI-1 system in the progression and treatment of depression. |

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.
