美国研究人员日前公布的一份研究报告显示,设法减少大脑内传送胰岛素信号的蛋白质,有可能帮助实验动物延长寿命。动物体内的胰岛素能指导细胞适时从血液中提取糖分,但随着年龄增长或者体重增加,细胞对胰岛素的反应变得迟钝,这时机体便需要更多胰岛素来控制糖分。科研人员此前在 A research report released recently by U.S. researchers shows that trying to reduce the protein in the brain that sends insulin signals may help to prolong lifespan in experimental animals. Insulin in animals guides the cells to extract sugar from the blood in time, but as they age or gain weight, the cells become slow to respond to insulin, and the body needs more insulin to control the sugar.
