Systemic inflammatory response is the major feature of ACLF. Gut microbiota dysbiosis impairs the intestinal barrier, facilitating the translocation of microorganisms and their metabolites into the liver and thereby exacerbating liver inflammation and disease progression. Recent studies have revealed that bacterial outer membrane vesicles (OMVs) derived from gut microbiota act as key mediators in microbiota-host cell communication. This article elucidates the possible roles of OMVs in ACLF inflammation and their underlying mechanisms.<\/jats:p>","DOI":"10.3389\/fmicb.2025.1608137","type":"journal-article","created":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T05:22:04Z","timestamp":1751606524000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["The role of bacterial outer membrane vesicles in inflammatory response of acute-on-chronic liver failure"],"prefix":"10.3389","volume":"16","author":[{"given":"Xiaojing","family":"Qin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanyao","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ninghui","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,4]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"96","DOI":"10.3389\/fmed.2020.00096","article-title":"Helicobacter pylori as an initiating factor of complications in patients with cirrhosis: a single-center observational study","volume":"7","author":"Abdel-Razik","year":"2020","journal-title":"Front.
