Currently, available AD drugs symptomatically treat AD with multiple adverse effects. Gefitinib (GE) is an epidermal growth factor receptor (EGFR) kinase inhibitor. EGFR is the preferred target for the treatment of AD, whereas the effect of GE in AD conditions is limited. The present study was designed to explore the ameliorative potential of GE in A\u03b21\u201342 oligomer-induced neurotoxicity in AD mice. AD was induced by intracerebroventricular (i.c.v.) injection of A\u03b21\u201342 oligomer (4 \u03bcg\/4 \u03bcL) into the lateral ventricles of the mouse brain. The test compound, i.e., GE (2 and 4 mg\/kg of body weight), was administered orally on days 10, 13, 16, 19, 22, 25, and 28, and the reference drug, i.e., donepezil (DP, 2 mg\/kg), was administered orally from the 10th to 28th days. The behavioral changes were screened by the Morris water maze (MWM) test. Furthermore, biomarkers i.e., brain acetylcholinesterase (AChE), thiobarbituric acid reactive substances (TBARS), and reduced glutathione (GSH) levels were estimated from brain samples. The AD-associated histopathological changes were analyzed by hematoxylin and eosin staining. The administration of GE significantly ameliorated the AD-associated behavioral, biochemical, and histopathological changes. The ameliorative effect of GE against the A\u03b21\u201342 oligomer-associated neurotoxicity was due to its potent inhibition of EGFR kinase activation, as well as its antioxidant and antilipid peroxidative effect.<\/jats:p>","DOI":"10.3390\/molecules27165182","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T03:33:20Z","timestamp":1660534400000},"page":"5182","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Epidermal Growth Factor Receptor Kinase Inhibitor Ameliorates \u03b2-Amyloid Oligomer-Induced Alzheimer Disease in Swiss Albino Mice"],"prefix":"10.3390","volume":"27","author":[{"given":"Jagadeesh","family":"Dhamodharan","sequence":"first","affiliation":[{"name":"Unit of Anatomy, Faculty of Medicine, AIMST University, Semeling, Bedong 08100, Kedah, Malaysia"},{"name":"Department of Pathology, Faculty of Medicine, Saveetha Institute of Medical & Technical Sciences (SIMATS), Saveetha University, Chennai 602105, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ganthimathy","family":"Sekhar","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, Saveetha Institute of Medical & Technical Sciences (SIMATS), Saveetha University, Chennai 602105, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0394-6104","authenticated-orcid":false,"given":"Arunachalam","family":"Muthuraman","sequence":"additional","affiliation":[{"name":"Unit of Pharmacology, Faculty of Pharmacy, AIMST University, Bedong 08100, Kedah, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"321","DOI":"10.1016\/j.jalz.2019.01.010","article-title":"2019 Alzheimer\u2019s Disease Facts and Figures","volume":"15","author":"Association","year":"2019","journal-title":"Alzheimer\u2019s Dement."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"129","DOI":"10.31887\/DCNS.2000.2.2\/aburns","article-title":"Diagnosis and Management of Alzheimer\u2019s Disease","volume":"2","author":"Burns","year":"2000","journal-title":"Dialogues Clin.
