The Intestinal Redox System and Its Significance in Chemotherapy-Induced Intestinal Mucositis

Figure 3

The intestinal oxidation-reduction (redox) system “Tai Chi” in normal physiological function. To support normal physiological function, the level of redox species was maintained in a certain limitation using subtle and complex regulatory methods, including local (induced by the oxidoreductases in different cell, tissue, and organ location) and global (induced by the products of oxidoreductases inside and outside the cell, even inside and outside the intestine) horizontal regulation. Additionally, the intestinal physiological function mainly includes the absorption of nutrients (water with the white point and inorganic salt with the black point) and the defense against pathogenic microorganisms.
