The reasons for these paradoxical results require investigation. We hypothesized that A\u03b2 exposure may cause persistent damage to cerebral endothelial cells even after A\u03b2 is removed (referred to as cerebrovascular endothelial damage memory). In this study, we aimed to investigate whether cerebrovascular endothelial damage memory exists in endothelial cells. hCMEC\/D3 cells were treated with A\u03b21\u201342 for 12 h and then A\u03b21\u201342 was withdrawn for another 12 h incubation to investigate whether cerebrovascular endothelial damage memory exists in endothelial cells. A mechanism-based kinetics progression model was developed to investigate the dynamic characters of the cerebrovascular endothelial damage. After A\u03b21\u201342 was removed, the sirt-1 levels returned to normal but the cell vitality did not improve, which suggests that cerebrovascular endothelial damage memory may exist in endothelial cells. Sirt-1 activator SRT2104 and NAD+ (Nicotinamide Adenine Dinucleotide) supplement may dose-dependently relieve the cerebrovascular endothelial damage memory. sirt-1 inhibitor EX527 may exacerbate the cerebrovascular endothelial damage memory. Kinetics analysis suggested that sirt-1 is involved in initiating the cerebrovascular endothelial damage memory; otherwise, NAD+ exhaustion plays a vital role in maintaining the cerebrovascular endothelial damage memory. This study provides a novel feature of cerebrovascular endothelial damage induced by A\u03b2.<\/jats:p>","DOI":"10.3390\/ijms21218226","type":"journal-article","created":{"date-parts":[[2020,11,3]],"date-time":"2020-11-03T09:09:32Z","timestamp":1604394572000},"page":"8226","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A\u03b2-Induced Damage Memory in hCMEC\/D3 Cells Mediated by Sirtuin-1"],"prefix":"10.3390","volume":"21","author":[{"given":"Haochen","family":"Liu","sequence":"first","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9781-6281","authenticated-orcid":false,"given":"Yixuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Xu","sequence":"additional","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huimin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoquan","family":"Liu","sequence":"additional","affiliation":[{"name":"Center of Drug Metabolism and Pharmacokinetics, China Pharmaceutical University, Nanjing 210009, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,3]]},"reference":[{"key":"ref_1","first-page":"291","article-title":"Preanalytical sample handling recommendations for Alzheimer\u2019s disease plasma biomarkers","volume":"11","author":"Bittner","year":"2019","journal-title":"Alzheimer\u2019s Dement.
