Albiflorin (AF), a traditional Chinese medicine, has shown exceptional therapeutic effects against pain and inflammation in various immune-related disorders. This study aimed to evaluate the protective effect of AF against sepsis-induced ALI in cecal ligation and puncture (CLP) mouse model, and investigate the associated mechanisms. <strong>Materials and methods:</strong> To demonstrate the protective effects of AF, lipopolysaccharide (LPS)-stimulated RAW264.7 cell line and CLP-induced sepsis were used as the <em>in vitro</em> and <em>in vivo</em> models, respectively. Cell Counting Kit (CCK)-8 assay was used to determine the cell viability of AF-treated RAW264.7 cells upon LPS challenge. The expression levels of pro-inflammatory cytokines and oxidative stress markers were evaluated by enzyme-linked immunosorbent assay (ELISA), Western blot analysis and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR), including toll-like receptor (TLR)-4, cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), phosphorylated nuclear factor-kappa B (p-NF-κB)/p65, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6. <strong>Results:</strong> AF administration alleviated the inflammation and oxidative stress in the pulmonary tissues of mice with CLP-induced sepsis, as well as in LPS-stimulated RAW264.7 cells. The protective effect of AF could be attributed to the attenuation of TLR-4/NF-κB/p65 activation. AF treatment reduced TLR-4 expression and dampened NF-κB signaling. In LPS-stimulated RAW264.7 cells, TLR-4 overexpression abrogated the protective effects of AF. In the mouse mode, the protective effect of AF against sepsis-induced ALI was comparable to the treatment effect of dexamethasone (DEX). <strong>Conclusion:</strong> These findings suggest that AF could serve as a protective agent against sepsis-induced lung injury by inhibiting the TLR-4/NF-κB pathway.</p></div>","PeriodicalId":360,"journal":{"name":"Journal of Functional Foods","volume":"107 ","pages":"Article 105633"},"PeriodicalIF":5.6,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1757689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
