Elevated plasma glucose leads to pancreatic β cell dysfunction and death in type 2 diabetes. Glycogen accumulation, due to impaired metabolism, contributes to this "glucotoxicity" via dysregulated biochemical pathways promoting β cell dysfunction. Here, we review emerging data, and re-examine published findings, on the role of glycogen in β cells in normoglycemia and in diabetes.
血糖升高会导致2型糖尿病患者的胰腺β细胞功能障碍和死亡。由于代谢受损导致的糖原积累,通过促进β细胞功能障碍的生化途径失调,促成了这种“糖毒性”。在此,我们回顾了有关糖原在正常血糖和糖尿病状态下β细胞中作用的新数据,并重新审视了已发表的研究结果。
