2型糖尿病的发病率和易感性随着年龄的增长而增加,但β细胞内导致这种易感性增加的潜在机制尚未完全阐明。在这里,我们回顾了衰老如何影响β细胞的增殖和再生能力,以及这如何影响β细胞群。此外,我们还回顾了β细胞功能随年龄的变化。虽然我们专注于不同的啮齿动物模型,提供了深入了解老化β细胞的特征,从非啮齿动物模型的有限知识也进行了审查。需要进一步的研究来确定潜在的β细胞靶点,以预防或减缓随着年龄的增长而发生的糖尿病的进展。
The incidence of and susceptibility to Type 2 diabetes increases with age, but the underlying mechanism(s) within beta cells that contribute to this increased susceptibility have not been fully elucidated. Here we review how aging affects the proliferative and regenerative capacity of beta cells and how this impacts beta cell mass. In addition we review changes that occur in beta cell function with age. Although we focus on the different rodent models that have provided insight into the characteristics of the aging beta cell, the limited knowledge from non-rodent models is also reviewed. Further studies are needed in order to identify potential beta cell targets for preventing or slowing the progression of diabetes that occurs with age.
