In experiment set up 1: Memory deficit was found in Morris water maze test on 14-16 days after STZ (ICV; 3mg/Kg) administration. STZ causes increased expression of GFAP, CD11b and TNF-α indicating glial activation and neuroinflammation. STZ also significantly increased the level of ROS, nitrite, Ca(2+) and reduced the mitochondrial activity in synaptosomal preparation illustrating free radical generation and excitotoxicity. Increased expression and activity of Caspase-3 was also observed in STZ treated rat which specify apoptotic cell death in hippocampus and cortex. STZ treatment showed decrease expression of post synaptic markers CaMKIIα and PSD-95, while, expression of pre synaptic markers (synaptophysin and SNAP-25) remains unaltered indicating selective post synaptic neurotoxicity. Oral treatment with Memantine (10mg/kg) and Ibuprofen (50 mg/kg) daily for 13 days attenuated STZ induced glial activation, apoptotic cell death and post synaptic neurotoxicity in rat brain. Further, in experiment set up 2: where memory function was not affected i.e. 7-9 days after STZ treatment. The level of GFAP, CD11b, TNF-α, ROS and nitrite levels were increased. On the other hand, apoptotic marker, synaptic markers, mitochondrial activity and Ca(2+) levels remained unaffected. Collective data indicates that neuroinflammatory process and oxidative stress occurs earlier to apoptosis and does not affect memory function. Present study clearly suggests that glial activation and post synaptic neurotoxicity are the key factors in STZ induced memory impairment and neuronal cell death.","is_dataset_classified":null,"base_score":4.969813299576001,"endowment":4.969813299576001,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24333387","pmcid":null,"openalex_id":"https://openalex.org/W1993441295","authors":[],"funders":[{"funder_name":"Council for Scientific and Industrial Research (CSIR)","grant_id":"","title":null}],"total_grants":1,"fwci":4.983,"citation_percentile":0.94845361,"influential_citations":0,"citation_trend":[{"year":2014,"count":4},{"year":2015,"count":12},{"year":2016,"count":9},{"year":2017,"count":16},{"year":2018,"count":14},{"year":2019,"count":13},{"year":2020,"count":18},{"year":2021,"count":14},{"year":2022,"count":9},{"year":2023,"count":10},{"year":2024,"count":10},{"year":2025,"count":11},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0091305713003353?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0091305713003353?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.pbb.2013.11.035","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/24333387","host_type":"repository"}],"fields_of_study":["Neuroinflammation and Neurodegeneration Mechanisms","Neuroscience and Neuropharmacology Research","Medicinal Plants and Neuroprotection","Animals","Base Sequence","DNA Primers","Injections, Intraventricular","Locomotion","Male","Memory Disorders","Neuroglia","Polymerase Chain Reaction","Rats","Rats, Sprague-Dawley","Streptozocin","Synapses"],"mesh_terms":["Animals","Base Sequence","Injections, Intraventricular","Locomotion","Male","Memory Disorders","Neuroglia","Streptozocin","Synapses","Polymerase Chain Reaction","Rats, Sprague-Dawley","DNA Primers","Rats"],"keywords":["Neurotoxicity","Synaptophysin","Streptozotocin","Morris water navigation task","Excitotoxicity","Chemistry","Endocrinology","Hippocampus","Internal medicine","Pharmacology","Apoptosis","Biology","Medicine","Programmed cell death","Toxicity","Biochemistry","Diabetes mellitus","Immunohistochemistry","Reactive oxygen species","Fura-2AM","GFAP","Free radicals","ROS","MTT","STZ","memory impairment","PSD","Reactive Nitrogen Species","Rns","Intracerebroventricular","Glial Activation","Camkiiα","Snap25","Dcf","Acsf","Artificial Cerebrospinal Fluid","Icv","Synaptic Markers","Elt","1-(Naphthyl) Ethylenediamine Dihydrochloride","2, 7 Dichlorofluorescein","Calmodulin Kinaseiiα","Escape Latency Times","Fura-2 Acetoxy-methyl Ester","Glial Fibric Acidic Protein","Neda","Post Synaptic Density","Synaptosome Associated Protein","3-[4,5-Dimethyl-thiozol-2-yl]-2,5 Diphenyl Tetrazolium Bromide"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T16:10:02.379903Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
