Abstract:As a star strain of next-generation probiotics, Akkermansia muciniphila (Akk) and its derivatives have been shown to be associated with inflammatory bowel disease (IBD), colorectal cancer (CRC), liver disease and other digestive disorders, and its positive roles and specific mechanisms in these diseases have been gradually uncovered. This review, based on the latest trials, provides a prospect for applying Akk in the clinical diagnosis and treatment of aforementioned diseases, from the perspectives of the biochemical characteristics of Akk strains and their main derivatives, and their protective roles and underlying mechanisms.
