摘要

大脑，像身体的其他部分一样，需要保持“体内平衡”(一种恒定的状态)才能发挥作用，这需要不断地清除代谢废物。几十年来，大脑的废物清除系统对科学家来说一直是个谜。几年前，在本文作者的帮助下，一组研究人员终于找到了答案。这一发现——被称为淋巴系统——将帮助我们了解有毒废物是如何在阿尔茨海默病等毁灭性疾病中积累的，并指出可能的预防策略。

The Brain's Waste-Removal System.

The brain, like other parts of the body, needs to maintain "homeostasis" (a constant state) to function, and that requires continuous removal of metabolic waste. For decades, the brain's waste-removal system remained a mystery to scientists. A few years ago, a team of researchers-with the help of our author-finally found the answer. This discovery-dubbed the glymphatic system- will help us understand how toxic waste accumulates in devastating disorders such as Alzheimer's disease and point to possible strategies to prevent it.
