Research status of mechanisms of pancreatic islet beta cell injury in type 2 diabetes
The number of type 2 diabetes(T2DM)accounts for more than 90%of all Diabetes mellitus(DM).The decrease of islet β cell mass and dysfunction are the core links of T2DM.With the prolongation of the course of disease,the number and function of β cells are gradually attenuated,and the damage mechanism has not been elucidated.At present,it is believed that it is closely related to metabolic stress,abnormal regulation of insulin secretion,changes in islet microenvironment,mitochondrial damage,glycolipid toxicity and dedifferentiation of islet β cells.Therefore,the mechanism of islet β cell damage in T2DM is summarized and elaborated in order to provide some reference for the precise intervention of T2DM.
