科学家已成功逆转老鼠的衰老 人类“返老还童”不再是梦

在哈佛医学院分子生物学家大卫·辛克莱（David Sinclair）的实验室中，年老的老鼠再次变得年轻，相信未来人类也可以实现逆转衰老。通过将成体细胞转变为干细胞的蛋白质，Sinclair 带领的团队成功将老鼠体内的衰老细胞重置为早期版本。

他带领的团队于 2020 年底发表的第一项突破中，视力不佳和视网膜受损的老老鼠突然可以再次看到，其视力有时可以与它们的后代相媲美。

在过去 20 年时间里，Sinclair 一直在研究逆转衰老的项目。他表示：“据我们所知，这是一个永久性的重置，我们认为这可能是一个普遍的过程，可以应用于整个身体来重置我们的年龄”。

在 CNN 合作举办的健康和保健活动 Life Itself 中，Sinclair 表示：“如果我们逆转衰老，这些疾病就不应该发生。我们今天拥有的技术能够让数百人不必担心在 70 多岁时患上癌症、在 80 多岁时患心脏病和在 90 多岁时患阿尔茨海默氏症”。

他兴奋的向台下观众表示：“这就是即将到来的世界。对于大部分人来说这只是时间问题，我们不知道这项突破能否在我们的有生之年实现”。

与 Sinclair 合作创建一个自己动手的生物时代的投资者惠特尼·凯西（Whitney Casey）说：“他的研究表明，你可以改变衰老，让生命更年轻。现在他想改变世界，让衰老成为一种疾病”。

虽然现代医学解决了疾病，但它并没有解决根本原因。Sinclair 说“对于大多数疾病来说，它本身就是衰老导致的。我们知道，当我们逆转像老鼠大脑这样的器官的年龄时，衰老的疾病就会消失。记忆回来了；不再有痴呆症。我相信，在未来，延缓和逆转衰老将是治疗困扰我们大多数人的疾病的最佳方法”。

In the first breakthrough published by his team at the end of 2020, old mice with poor eyesight and impaired retina suddenly saw again that their eyesight was sometimes comparable to that of their offspring.

For the past 20 years, Sinclair has been working on projects to reverse aging. "as far as we know, this is a permanent reset and we think it may be a universal process that can be applied to the whole body to reset our age," he said.

"if we reverse aging, these diseases should not occur," Sinclair said at Life Itself, a health and health campaign co-organized by CNN. The technology we have today allows hundreds of people not to worry about developing cancer in their 70s, heart disease in their 80s and Alzheimer's in their 90s.

"this is the world to come," he told the audience excitedly. For most people, it's only a matter of time, and we don't know if this breakthrough can be achieved in our lifetime.

"his research shows that you can change aging and make your life younger," said Whitney Casey, an investor who worked with Sinclair to create a do-it-yourself biological era. Now he wants to change the world and make aging a disease.

Although modern medicine has solved the disease, it does not solve the root cause. "for most diseases, it is itself caused by aging," Sinclair said. We know that when we reverse the age of organs like the mouse brain, the aging disease disappears. The memory is back; there is no more dementia. I believe that in the future, delaying and reversing aging will be the best way to treat the diseases that afflict most of us.
