Scientists revealed in a groundbreaking study that they have successfully slowed aging process in mice, and they’re hoping the development will lead to an anti-ageing pill that would work on humans.

In a five-year study, published in journal Cell, researchers report that they have found a molecule that essentially reactivates faltering blood flow in elderly mice, Time Magazine reports. Compromised blood flow is a major component of ageing, as it deprives tissues and organs, including the brain, of the nutrients and oxygen they need to function.

據(jù)《時代周刊》報道，研究人員在《細胞》雜志上發(fā)表了一項為期五年的研究報告，稱他們已經(jīng)發(fā)現(xiàn)了一種分子，這種分子本質(zhì)上可以重新激活年老老鼠不穩(wěn)定的血流。血液老化是衰老的根源，因為它剝奪了需要發(fā)揮作用的組織和器官(包括大腦)所需的營養(yǎng)和氧氣。

The compound, called nicotinamide mononucleotide (NMN), a form of vitamin B3 that is naturally produced by the body, was fed to the 20-month-old mice, an age comparable to 70 years in people. After being treated with NMN for two months, it increased muscular blood flow, enhanced physical performance and endurance, and the older mice eventually became as fit and strong as the younger ones.

一種叫做煙酰胺單核苷酸(NMN) 的化合物被喂給20個月大的老鼠，這個年齡相當于人類70歲。NMN是身體自然生成的維生素B3的一種形式。在接受NMN治療兩個月后，老鼠肌肉的血流量增加了，體力和耐力也增強了，年老的老鼠最終變得和年輕的老鼠一樣健康強壯。
