Research progress of the bidirectional interaction between gut microbiota and brain / 上海交通大学学报（医学版）

ABSTRACT

The gut-brain axis (GBA) is a nerve-endocrine mediated bidirectional communication system between the gut and brain, which links the cognition and emotion in brain to peripheral intestinal function. In recent years, many researches have showed that colonized intestinal microbiota plays an important role in the communication between gut and brain. On one hand, microbiota can influence the development and function of brain via GBA. On the other hand, brain can also change the composition of gut microbiota. These findings gradually become a novel medical research highlight, i.e. the microbiota-gut-brain axis. This paper reviews the interaction between gut microbiota and brain via GBA in order to provide supports for studying functions of gastrointestinal tract and brain, as well as the treatment of related diseases.
