Summary. Type 2 diabetes mellitus (T2DM) - a metabolic disorder characterized by chronic hyperglycemia, developing as a result of violations of the interaction of insulin with tissue cells. Diabetes - one of the most common endocrine disease. The frequency of diabetes mellitus in average ranges from 1.5-3%, increasing in the developed world (5-6%). In the world there are about 200 million. Diabetes, with almost 90% of them suffer from type 2 diabetes. The problem of type 2 diabetes continues to be the most urgent task of modern endocrinology. The review is devoted to new data from the literature regarding the molecular and genetic mechanisms of type 2 diabetes. Based on the literary analysis conducted, it should be noted that the molecular basis of etiopathogenesis type 2 diabetes are complex and significant role in the formation of insulin resistance and type 2 diabetes play a violation of the b-cells. Of great importance in the development of insulin resistance have tumor necrosis factors having a plurality of biomedical effects.
