Antidepressants are commonly used in patients before and after their diagnosis of AD. To date, the relationship between antidepressants and AD remains unclear.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> In our study, we administered sertraline or paroxetine to wild type (WT) and APPswe\/PSEN1dE9 (APP\/PSEN1) transgenic mouse models for up to 12\u00a0months. We quantified the drug concentrations using LC-MS\/MS analysis and measured serum serotonin level using an ELISA assay. Additionally, we evaluated the amyloid burdens through thioflavin-S and Congo red stainings, and recognition memory using the novel object recognition test.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Our findings revealed that mice treated with paroxetine exhibited a significantly higher level of weight gain compared to the control group and increased mortality in APP\/PSEN1 mice. After 12\u00a0months of antidepressant treatment, the sertraline level was measured at 289.8\u00a0ng\/g for cerebellum, while the paroxetine level was 792.9\u00a0ng\/g for cerebellum. Sertraline significantly increased thioflavin-S and Congo red depositions, along with gliosis, in both isocortex and hippocampus of APP\/PSEN1 mice compared to the control group. Both antidepressants also led to a decreased recognition index in APP\/PSEN1 mice.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> These findings suggest a potential role of sertraline in AD pathogenesis, emphasizing the need to reassess the use of these antidepressants in patients with AD.<\/jats:p>","DOI":"10.3389\/fphar.2023.1260838","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T04:14:01Z","timestamp":1704687241000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Antidepressant sertraline increases thioflavin-S and Congo red deposition in APPswe\/PSEN1dE9 transgenic mice"],"prefix":"10.3389","volume":"14","author":[{"given":"Ming-Hsuan","family":"Liao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yen-Kuang","family":"Lin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fong-Ying","family":"Gau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Che","family":"Tseng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Da-Chih","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chu-Yuan","family":"Hsu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuo-Hsuan","family":"Chung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rung-Chi","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaur-Jong","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chee Kin","family":"Then","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shing-Chuan","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"738","DOI":"10.1038\/mp.2011.26","article-title":"Antidepressants increase human hippocampal neurogenesis by activating the glucocorticoid receptor","volume":"16","author":"Anacker","year":"2011","journal-title":"Mol.
