尽管目前媒体关注的焦点是新冠肺炎,但它并不是目前唯一的大流行。还有一种全球性的糖尿病大流行。它是由荷尔蒙胰岛素不足引起的,胰岛素能降低血糖水平。在这里,我们重点介绍了最近的工作,这些工作解决了胰岛素通常是如何从胰腺的β细胞分泌的问题,以及糖尿病患者这一过程中出现了什么问题。我们专注于ATP敏感性钾通道的代谢调节,它是一种ATP门控的膜孔,调节胰岛素的分泌。我们发现,当这个小孔关闭时,胰岛素被释放,当这个小孔打开时,胰岛素释放被阻止。正如可以预料的那样,削弱ATP关闭通道能力的基因突变会导致新生儿糖尿病。我们还考虑如果β细胞代谢不能产生足够的三磷酸腺苷来关闭通道,是否会导致2型糖尿病β细胞功能的进行性下降。
Despite the current media focus, Covid-19 is not the only current pandemic. There is also a global pandemic of diabetes. It is caused by an insufficiency of the hormone insulin, which lowers blood glucose levels. Here we highlight recent work that addresses the question of how insulin is normally secreted from the β-cells of the pancreas and what goes wrong with this process in diabetes. We focus on the metabolic regulation of the ATP-sensitive potassium channel, an ATP-gated membrane pore that regulates insulin secretion. We show that when this pore is shut, insulin is released, and when it is open, insulin release is prevented. As may be expected, genetic mutations that impair the ability of ATP to close the channel cause neonatal diabetes. We also consider if a failure of β-cell metabolism to generate enough ATP to close the channel may lead to the progressive decline in β-cell function in type 2 diabetes.
