The focus was investigating changes inflammatory, gut microbiota, serum lipopolysaccharide (LPS) inflammatory cytokines. Methods Mice were exposed a DSS induce administered as probiotic intervention. experiment included determination body weight, colon length, histological examinations, analysis LPS cytokines over 12 weeks. In addition, liver function, oxidative stress intestinal microbiota examined understand comprehensive LRa05. Results Low-dose did not lead significant length or histologic signs inflammation. However, it led increase levels LPS, tumor necrosis factor-alpha (TNFα) interleukin-6 (IL6).

In the advancement of Inflammatory Bowel Disease (IBD) treatment, existing therapeutic methods exhibit limitations; they do not offer a complete cure for IBD and can trigger adverse side effects. Consequently, exploration novel therapies multifaceted treatment strategies provides patients with broader range options. Within framework IBD, gut microbiota plays pivotal role in disease onset through diverse mechanisms. Bacteriophages, as natural microbial regulators, demonstrate remarkable specificity by accurately identifying eliminating specific pathogens, thus holding promise. Although clinical trials have affirmed safety phage therapy, its efficacy is prone to external influences during storage transport, which may affect infectivity regulatory roles within microbiota. Improving stability precise dosage control bacteriophages—ensuring robustness consistent dosing, targeted delivery infection sites—is crucial.
