Moreover, it is already established that metals (particularly copper, zinc and iron) have a key role in the pathogenesis of AD. In order to reduce the A\u03b2 plaque burden and overcome the side effects from the synthetic inhibitors, the current study was designed to focus on direct inhibition of with or without metal-induced A\u03b2 fibril formation and aggregation by using olive biophenols. Exposure of neuroblastoma (SH-SY5Y) cells with A\u03b242 resulted in decrease of cell viability and morphological changes might be due to severe increase in the reactive oxygen species (ROS). The pre-treated SH-SY5Y cells with olive biophenols were able to attenuate cell death caused by A\u03b242, copper- A\u03b242, and [laevodihydroxyphenylalanine (l-DOPA)] l-DOPA-A\u03b242-induced toxicity after 24 h of treatment. Oleuropein, verbascoside and rutin were the major anti-amyloidogenic compounds. Transgenic mice (APPswe\/PS1dE9) received 50 mg\/kg of oleuropein containing olive leaf extracts (OLE) or control diet from 7 to 23 weeks of age. Treatment mice (OLE) were showed significantly reduced amyloid plaque deposition (p &lt; 0.001) in cortex and hippocampus as compared to control mice. Our findings provide a basis for considering natural and low cost biophenols from olive as a promising candidate drug against AD. Further studies warrant to validate and determine the anti-amyloid mechanism, bioavailability as well as permeability of olive biophenols against blood brain barrier in AD.<\/jats:p>","DOI":"10.3390\/ijms20010125","type":"journal-article","created":{"date-parts":[[2018,12,31]],"date-time":"2018-12-31T07:22:30Z","timestamp":1546240950000},"page":"125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Olive Biophenols Reduces Alzheimer\u2019s Pathology in SH-SY5Y Cells and APPswe Mice"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4955-5125","authenticated-orcid":false,"given":"Syed Haris","family":"Omar","sequence":"first","affiliation":[{"name":"School of Biomedical Sciences, Faculty of Sciences and Graham Centre for Agricultural Innovation, Charles Sturt University, Wagga Wagga, NSW 2678, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J.","family":"Scott","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, Faculty of Sciences and Graham Centre for Agricultural Innovation, Charles Sturt University, Wagga Wagga, NSW 2678, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam S.","family":"Hamlin","sequence":"additional","affiliation":[{"name":"School of Science &amp; Technology, University of New England, Armidale, NSW 2351, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan K.","family":"Obied","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, Faculty of Sciences and Graham Centre for Agricultural Innovation, Charles Sturt University, Wagga Wagga, NSW 2678, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1774","DOI":"10.1126\/science.1197623","article-title":"Decreased clearance of CNS beta-amyloid in Alzheimer\u2019s disease","volume":"330","author":"Mawuenyega","year":"2010","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"595","DOI":"10.15252\/emmm.201606210","article-title":"The amyloid hypothesis of Alzheimer\u2019s disease at 25 years","volume":"8","author":"Selkoe","year":"2016","journal-title":"EMBO Mol.
