Rapamycin is a well-known drug that helps individuals who have had transplants avoid rejection.  In new studies, it has shown you to prolong the lives of mice by an incredible 14%.  This was even proven when administered to mice even in a more mature age.  Until this recent find, only caloric restrictions in humans actually extended life.  Therefore, rapamycin is truly a breakthrough in prolonging life.


Tests were conducted in three institutions in the United States.  All the mice had genetic differences.  The necessary in order to avoid any single strain.  The mice all had to be around 20 months old, which would be about 60 years old to us.

Is it Too Soon for Humans?

Although it is quite an early and too soon for humans, scientists claim that the results are quite impressive.  Of course dosage for humans, has not been properly calculated as of yet.  One problem that arises with rapamycin is that it is known to affect the immune system, making individuals be more susceptible to contracting infections.  They are working on altering it in order to lessen those affects.  They believe they will be able to change it enough to target other molecules so that the immune system is not affected.

At this moment, these antiaging drugs will not be tested on humans.  Much more research has to go into rapamycin with more lab mice, worms, flies and the like.
