| Summary: | Abstract Inflammatory bowel disease (IBD) is characterized by compromised intestinal barrier function and a lack of effective treatments. Probiotics have shown promise in managing IBD due to their ability to modulate the gut microbiota, enhance intestinal barrier function, and exert anti-inflammatory effects. However, the specific mechanisms through which probiotics exert these therapeutic effects in IBD treatment remain poorly understood. Our research revealed a significant reduction of Lactiplantibacillus plantarum (L. plantarum) in the gut microbiota of IBD patients. L. plantarum is a well-known probiotic strain in the list of edible probiotics, recognized for its beneficial effects on gut health, including its ability to strengthen the intestinal barrier and reduce inflammation. We demonstrated that supplementation with L. plantarum could alleviate IBD symptoms in mice, primarily by inhibiting apoptosis in intestinal epithelial cells through L. plantarum’s bacterial extracellular vesicles (L. plant-EVs). This protective effect is dependent on the efficient uptake of L. plant-EVs by intestinal cells. Intriguingly, watermelon enhances L. plantarum colonization and L. plant-EVs release, further promoting intestinal barrier repair. Our findings contribute to the understanding of L. plant-EVs in the probiotic-based therapeutic approach for IBD, as they are promising candidates for nanoparticle-based therapeutic methods that are enhanced by natural diets such as watermelon. This study thereby offers a potential breakthrough in the management and treatment of IBD. Graphical Abstract |
