Project description:The pharmacological significance of B vitamins, essential for various metabolic processes, and the therapeutic potential of probiotics in gastrointestinal health have been well-documented. However, the interactions between these entities remain poorly understood. In this study, we endeavored to elucidate the potential interplay between B vitamins and probiotics utilizing liquid chromatography-triple quadrupole mass spectrometry, pharmacokinetic modeling, and 16S rRNA gene sequencing. Employing healthy and pseudo-germ-free rat models, we revealed that probiotics significantly improve the absorption of B1, B3, B5, and B12, and that the gut microbiota played a mediating role in this enhanced absorption of B vitamins by probiotics. High-throughput genetic sequencing uncovered a synergistic effect of B vitamins and probiotics in modulating the gut microbiota, particularly increasing the abundance of Verrucomicrobia and Akkermansia. Furthermore, in vitro experiments demonstrated that probiotics used in this study had a relatively minor influence on the production and permeability of B vitamins, while B vitamins did not significantly contribute to the growth, auto-aggregation, and adhesion of probiotics. In summary, a complex network connection exists between B vitamins and probiotics, wherein the gut microbiota emerges as a pivotal factor that cannot be overlooked.

Project description:By combining directed evolution and synthetic biology, we engineered novel synthetic yeasts probiotics for the dynamic modulation of intestinal inflammation. In this experiment we treated TNBS-colitis induced mice with these probiotics and test the amelioration of immune response in the transcriptional level in the colon.
