The incidence of DED has been gradually increasing with the high frequency of use of electronic devices. It has been demonstrated that celastrol (Cel) has excellent therapeutic efficacy in ocular disorders. However, the poor water solubility and short half-life of Cel limit its further therapeutic applications. In this work, a reactive oxygen species (ROS) sensitive polymeric micelle was fabricated for Cel delivery. The micelles improve the solubility of Cel, and the resulting Cel loaded micelles exhibit an enhanced intervention effect for DED. The\n                    <jats:italic>in vitro<\/jats:italic>\n                    results demonstrated that Cel-nanomedicine had a marked ROS responsive release behavior. The results of\n                    <jats:italic>in vitro<\/jats:italic>\n                    and\n                    <jats:italic>in vivo<\/jats:italic>\n                    experiments demonstrated that Cel has excellent biological activities to alleviate inflammation in DED by inhibiting TLR4 signaling activation and reducing pro-inflammatory cytokine expression. Therefore, the Cel nanomedicine can effectively eliminate ocular inflammation, promote corneal epithelial repair, and restore the number of goblet cells and tear secretion, providing a new option for the treatment of DED.\n                  <\/jats:p>","DOI":"10.1088\/1361-6528\/ad4ee5","type":"journal-article","created":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T09:13:40Z","timestamp":1717406020000},"page":"335102","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["ROS-responsive celastrol-nanomedicine alleviates inflammation for dry eye disease"],"prefix":"10.1088","volume":"35","author":[{"given":"Bingbing","family":"Cui","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingyun","family":"Ning","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huayang","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruixing","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanrong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0471-4540","authenticated-orcid":true,"given":"Jingguo","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,6,3]]},"reference":[{"key":"nanoad4ee5bib1","doi-asserted-by":"publisher","DOI":"10.1016\/j.addr.2022.114582","article-title":"Novel drug delivery systems for the management of dry eye","volume":"191","author":"Nagai","year":"2022","journal-title":"Adv.
