However, therapeutic effect is usually contingent on the ability of the probiotic cells to adhere to and colonize the gastrointestinal tract. Pediococcus pentosaceus Li05 has previously been shown antiinflammatory effect, however, its mucoadhesive ability limited further application. In this study, MUC2 antibody was used as an adhesin and conjugated to the surface of Li05 (M-Li05) and our results demonstrated that the adhesion and colonization resistance were significantly improved in vitro. Moreover, competitive adhesion experiments in mice demonstrated that Li05 outcompeted Citrobacter rodentium; an effect even more pronounced with M-Li05 . The study also showed that M-Li05 significantly reduced colonic histological injury, alleviated inflammation and decreased pathogens colonization in the C. rodentium-infected and DSS-induced colitis mouse model. In summary, the results demonstrated that M-Li05 showed promise for future application as a therapeutic strategy for colitis. |  |  |\n| Inflammatorybowel disease(IBD)is a group ofdiseases including ulcerative colitis (UC) and Crohn’s disease (CD), characterized by chronic inflammation of the gastrointestinal (GI) tract1. Many factors including diet, genetics, host immunity, and intestinal microbiome, are involved in the development of IBD2–5. The composition of the gut microbiota of patients with IBD differs markedly from that of healthy individuals6,7. Many studies have shown that IBD patients demonstrated a reduced diversity of their gut microbiota, with the lack of diversity among Firmicutes being especially notable1.\u003Cbr>Probiotics are defined as “live microorganisms that, when given insufficient amounts, provide health benefits to the host”8. Many reports have demonstrated the anti-inflammation efficacy of various probiotic bacteria for IBD in clinical trials and animal experiments9–12. The probiotic strain Pediococcus pentosaceus Li05 can strengthen the intestinal epithelial barrier function, modulate host immunity and gut microbiota in Clostridiodies difficile infected colitis, dextrate sulfate sodium (DSS) -induced colitis and CCl4-induced cirrhosis13–15. However, the | application of Li05 is limited due to the strain’s susceptibility to harsh conditions exacerbated by chemical, physical, and biological factors during its transmission through the gastrointestinal tract, and poor adhesion to the intestinal mucosa15, 16.\u003Cbr>We have previously successfully enhanced the viability of Li05 in harsh conditions through encapsulating Li05 in microcapsules15, but its adhesion in the colon remains to be improved. Successful colonization in the intestine is a necessary criterion for evaluating whether probiotics can have a long-term effect17. Mucosal adhesion is considered a critical step in probiotic colonization which is achieved by stable binding of the probiotic cells to the mucus through specific interactions between adhesins and complementary receptors18, like mucin 2 (MUC2), a predominant component of the intestinal mucosa19. One way to enhance the adhesive ability of the probiotic to the mucosa is by directly increasing the amount of adhesins on the bacterial surface. Synthetic adhesins in the form of antibodies (antiMUC2) (aMUC2) can be conjugated to the probio","cbCaiaH63MdjA8yC","https://ap.wps.com/l/cbCaiaH63MdjA8yC","pdf",11359642,14,"English","# Background and rationale\n## Limitations of Pediococcus pentosaceus Li05\n## Role of mucosal adhesion and MUC2\n# Surface modification strategy\n## Conjugating MUC2 antibody to Li05\n## Expected benefits of M-Li05\n# Experimental evaluation\n## In vitro adhesion and colonization resistance\n## Mouse infection models for acute colitis\n# Outcomes and implications","[{\"question\":\"Why is adhesion important for probiotic therapy?\",\"answer\":\"Therapeutic effects rely on probiotic cells adhering to and colonizing the gastrointestinal tract.
