"Gut microbiota control our behavior! "
"It's actually the bacteria in our gut that makes us fat!"
The truth is that all of this sounds like a lie. It is estimated that there are as many, if not more, intestinal bacteria living in our intestinal tract, than there are cells in our entire body. Gut microbiota has various effects on our body by crosstalk with host intestinal neurons, endocrine cells, and immune cells. In this lecture, the functions of the gut microbiota that contribute to the maintenance and promotion of host health will be outlined. In addition, the roles of the gut microbiota in the development of the intestinal immune system, various diseases caused by imbalances in the gut microbiota, and methods of disease prevention and treatment through appropriate control of gut microbiota will be explained, including the latest findings.
