《法新社巴黎5月1日电》科学家今天表示,他们发现大脑里的一个区域控制着身体的衰老,可以通过它来操纵实验鼠的寿命。这一研究成果或许朝着发现减缓人类衰老的秘诀迈进了一步,但还有待在人体上试验。发表于《自然》周刊的研究论文指的是下丘脑,这个大脑区域在我们称之为衰老的身体状况逐渐恶化过程中调节着生长、繁殖和代谢。虽然科学家早就怀疑大脑协调着这个过程,但这是首次发现相关证据。研究小组称,他们可以激活或抑制下丘脑的NF—k B信号传导分子,进而影响可促成神经元(即大脑的
AFP, PARIS, May 1 Scientists said today that they found an area in the brain controlling the aging of the body through which mice can manipulate their lifespan. This research may take a step toward discovering the secret of slowing down human aging, but it has yet to be tested on the human body. The research paper published in Nature magazine refers to the hypothalamus, a region of the brain that regulates growth, reproduction, and metabolism during the gradual deterioration of what we call aging. Although scientists have long suspected that the brain is coordinating this process, this is the first time evidence has been found. The team said they can activate or inhibit the hypothalamic NF-κB signaling molecules, which in turn can affect neurons (ie, the brain’s
