This design simultaneously endowed the complex with excellent gastrointestinal resistance, antioxidant, and anti-inflammation abilities. Moreover, the inulin in the nanoparticles acts as a prebiotic, promoting the <em>Bifidobacterium's</em> rapid proliferation to exert effects within a short period. Compared with uncoated BL, BL@PP-NPs exhibited excellent gastric acid tolerance and up to 31.32-fold colonic colonization, and the ROS scavenging and proliferative capacity were increased by 5.61- and 1.39-fold, respectively. In a mouse model of dextran sulfate sodium (DSS)- and trinitrobenzene sulfonic acid (TNBS)-induced colitis, the components of Inulin/TFA/SS NPs synergized with probiotics to efficiently treat IBD by attenuating oxidative stress, decreasing inflammation, repairing intestinal barrier, and promoting the rapid proliferation of probiotics to reverse gut microbial disorders. Collectively, food-grade BL@PP-NPs represent a novel approach to probiotic modification that offers an effective, safe, and synergistic therapy for IBD.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"350 ","pages":"Article 123063"},"PeriodicalIF":10.7,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142745931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
