Short chain fatty acid: a messenger of gut-organ axis for disease regulation / 药学学报

ABSTRACT

Gut microbiota is a complex and dynamic system, and is essential for the health of the body. As the "second genome" of the body, it can establish communication with the important organs by regulating intestinal nerves, gastrointestinal hormones, intestinal barrier, immunity and metabolism, thus affecting host′s physiological functions. Short chain fatty acid (SCFA), known as one important metabolite of intestinal microbiota, is regarded as a significant messenger of the gut-organ communication, due to its extensive regulation in the body′s immunity, metabolism, endocrine and signal transduction. In this review, we summarize the interaction between gut-liver/brain/kidney/lung axis and diseases, and focus on the role and mechanism of SCFA in the gut-organ communication, hoping to provide new ideas for the treatment of the related diseases.
