The biofunction of Akkermansia muciniphila in intestinal-related diseases.

Abstract

Intestinal homeostasis is essential for maintaining human health, and its dysfunction is related to the onset and progression of various diseases, including immune and metabolic disorders, and even tumorigenesis. Intestinal microbiota plays a critical role in intestinal homeostasis, with Akkermansia muciniphila (A. muciniphila) emerging as a key commensal bacterium utilizing mucin as its sole carbon and nitrogen source. A. muciniphila has been recognized in both experimental and clinical studies for its beneficial role in managing intestinal inflammation, tumors, functional gastrointestinal disorders, and secondary conditions such as liver and metabolic diseases. This review provides a comprehensive overview of the research history and current understanding of A. muciniphila, its association with various intestinal-related diseases, and the potential mechanisms behind its effects. This paper also explores the possibilities of leveraging the probiotic enzyme such as the active ingredients of A. muciniphila for the innovative clinical treatment of intestinal-related diseases.
