Dietary Protein Sources Differentially Affect the Growth of Akkermansia muciniphila and Maintenance of the Gut Mucus Barrier in Mice
Scope: The gut microbiota plays an essential role in linking diet to host health. The specific role of different dietary proteins on the gut microbiota and health is less understood. Here, the impact of proteins derived from chicken and soy on the gut microbiota and host gut barrier in C57BL/6 mice is investigated. Methods and results: Specific-pathogen-free and germ-free mice are assigned to either a chicken- or a soy protein-based diet for 4 weeks. Compared with a chicken-protein-based diet, intake of a soy-protein-based diet reduces the abundance of A. muciniphila and the number of goblet cells, lowers the level of Muc2 mRNA, and decreases the thickness of the mucus layer in the colon of specific-pathogen-free mice. In germ-free mice, colonization with A. muciniphila combined with intake of a chicken-protein-based diet results in a higher expression of the Muc2 mRNA in colon, and surprisingly, an increased potential for oxidative phosphorylation in A. muciniphila compared with colonized mice fed a soy-protein-based diet. Conclusion: These findings suggest possible mutually beneficial interactions between the growth and function of A. muciniphila and host mucus barrier in response to intake of a chicken-protein-based diet contrasting the intake of a soy-protein-based diet.
