Abstract

Type 2 diabetes mellitus (T2DM)is a chronic inflammatory disease characterized by insulin resistance and glucose intolerance resulting in dysfunction, destruction of beta cells or both. One of the main causes of T2DM is obesity, which correlates with the establishment of an inflammatory process and the activation of innate immunity cells, called metabolic inflammation. It is known that intestinal homeostasis is determined by a balance between Treg and Th17 lymphocytes, which is induced in the presence of IL-1beta and IL-23 in response to components of the intestinal microbiota. Furthermore, it was shown that Th17 lymphocytes in the intestine are essential for controlling the colonization and bacterial translocation by producing antimicrobial peptides, and cytokines such as IL-17 and IL-22. Some studies have reported that obese and diabetic individuals show changes in the proportion and configuration of bacteria in the intestinal microbiota called intestinal dysbiosis. Such changes in the microbiome can result in disruption of the intestinal barrier, increased permeability, endotoxemia and metabolic inflammation. However, there are no reports on the importance of cytokines produced by Th17 lymphocytes in the control of intestinal dysbiosis and its implication in the development of obesity-induced T2DM.
