Estrogen promotes lupus in human and mouse models of SLE. In this study, we conducted an in vivo study to investigate the relationship between two estrogen receptors (ER&lt;sub&gt;\u03b1&lt;\/sub&gt; and ER&lt;sub&gt;\u03b2&lt;\/sub&gt;) and platelet-activating factor acetylhydrolase (PAF-AH) on the symptoms of SLE. Methods: Skin and facial features, serum PAF-AH activity, tumor-necrosis factor-alpha (TNF-\u03b1), and anti-double stranded DNA (anti-dsDNA) antibody titer, all of which are central to the classification and pathogenesis of SLE, were measured in SLE model mice injected with various ER antagonists. Results: In SLE mice, the injection of an ER&lt;sub&gt;\u03b2&lt;\/sub&gt; antagonist 4-[2-phenyl-5,7-bis(trifluoromethyl)pyrazolo[1,5-\u03b1]pyrimidine-3-yl]-phenol induced the expression of facial erythema (especially around a cheek). The injection of an ER&lt;sub&gt;\u03b1\/\u03b2&lt;\/sub&gt; antagonist tamoxifen induced hair-loss on the head and the neck. The injection of an ER&lt;sub&gt;\u03b1&lt;\/sub&gt; antagonist methylpiperidino pyrazole or tamoxifen increased PAF-AH activity and decreased TNF-\u03b1 levels and anti-dsDNA antibody in mouse serum. Conclusions: The activation of ER&lt;sub&gt;\u03b1&lt;\/sub&gt; and inactivation of ER&lt;sub&gt;\u03b2&lt;\/sub&gt; can cause inflammatory and cutaneous symptoms of SLE, respectively, implying that ER&lt;sub&gt;\u03b1&lt;\/sub&gt; antagonists and\/or ER&lt;sub&gt;\u03b2&lt;\/sub&gt; agonists can be useful for the prevention and treatment of SLE. <\/jats:p>","DOI":"10.1159\/000543797","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T12:02:33Z","timestamp":1737979353000},"page":"254-260","source":"Crossref","is-referenced-by-count":3,"title":["Estrogen Receptors and Platelet-Activating Acetylhydrolase Activity in the Pathogenesis of Systemic Lupus Erythematosus"],"prefix":"10.1159","volume":"110","author":[{"given":"Akira","family":"Sato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuta","family":"Ogawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayano","family":"Yabuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Genta","family":"Sato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hina","family":"Nemoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Ohira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2025,1,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.56.7.481"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3389\/fmed.2022.906475"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.steroids.2024.109426"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsbmb.2024.106539"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinthera.2014.07.021"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2018.02279"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1210\/er.2007-0001"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/s0021-9258(19)70658-9"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1172\/JCI111957"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1042\/bj2920617"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1177\/0394632015600598"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/s0163-7827(99)00016-8"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/s0021-9258(18)38167-5"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1038\/sj.gene.6364458"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.30330"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/35.11.1067"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1191\/0961203302lu306rr"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2249.2000.01392.x"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2567.1997.00122.x"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1210\/endo.143.3.8704"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s10067-007-0568-3"}],"container-title":["Pharmacology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/pha\/article-pdf\/doi\/10.1159\/000543797\/4328203\/000543797.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000543797","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T16:01:10Z","timestamp":1755532870000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000543797"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,27]]},"references-count":21,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,8,18]]},"published-print":{"date-parts":[[2025,8,20]]}},"URL":"https:\/\/doi.org\/10.1159\/000543797","archive":["Portico"],"relation":{},"ISSN":["0031-7012","1423-0313"],"issn-type":[{"value":"0031-7012","type":"print"},{"value":"1423-0313","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1,27]]}}}
