Zusammenfassung: | Manipulation of gut microbiota by bacterial metabolites has shown protective effects against colitis; while the efficacy is strictly limited by the poor oral delivery efficiency and single drug usage. Here, a novel prebiotics and postbiotics synergistic delivery microcapsule composed of indole‐3‐propionic acid (IPA) postbiotic and three prebiotics including alginate sodium, resistant starch (RS), and chitosan via microfluidic electrospray for preventing and treating colitis are proposed. It is found that oral administration of IPA microcapsules (IPA@MC) to mice can exert significant protective effects to colitis, suggesting the therapeutic synergy between prebiotics and postbiotics. Furthermore, the mechanism of the IPA@MC is revealed in modulating the gut microbiota, that is by significantly increasing the overall richness and abundance of short‐chain fatty acids (SCFA) producing bacteria such as Faecalibacterium and Roseburia. These results indicate that the prebiotics and postbiotics synergistic delivery microcapsules are ideal candidates for treating colitis.
Novel prebiotics and postbiotics synergistic delivery microcapsule is developed via microfluidic electrospray for treating colitis. Oral administration of the indole‐3‐propionic acid microcapsules can exert significant protective effects to colitis by modulating the health of gut microbiota in mice. The richness and abundance of short‐chain fatty acids producing bacteria are significantly increased after receiving the microcapsule. |
