Anti-aging drugs prolong life by 14%?

In the British " Nature " magazine recently published a new research project, US researchers have discovered that a common immunosuppressive drug may prolong the life of laboratory mice. This is the first drug discovered that can extend the life of mammals.

According to the report on the " Nature " website, the team of researchers from three US organizations conducted the experiments in turn, using all 2000 mice to conduct the experiment. The results showed that, if starting the test at the time the experimental mice were 20 months old (equivalent to 60 years of age in humans), adding rapamycin in the diets of the experimental mice, their lifespan would be extended to about 14 %

Rapamycin is an immunosuppressive drug, often used to prevent transplantation when parts of the reaction occur. Studies have shown that this drug can prolong the lifespan of invertebrates such as microzyme, eelworm, Drosophila .

Researchers have shown, although research shows that rapamycin may prolong the life of laboratory rats, but if you want to use " long-life " medicine for humans, it's still too early. Because of the immunosuppressive effect of rapamycin, it is easier for drug users to be attacked by infectious diseases.

In addition, drug use is also a problem, the amount of medicine used for normal people is 2 ~ 5mg / day, while the amount of medicine used for rats is 2.24mg / kg / day.
