Tetsuya Mine

The intestinal tract consists of vast microbes and host environment including metabolism and immunology, which is good for health. If these factors are dramatically changed, it is capable that some kinds of diseases can develop and suffered host may be fatal. Injury to intestinal epithelial barrier function and innate immune bacterial killing function, due to uptake of vast food containing much bacteria and risky antigens, can lead hosts to develop fatal inflammatory responses.
