Rapamycin protects immune cells from DNA damage in aging adults

Rapamycin significantly reduces DNA damage in aging immune cells, offering a potential avenue to combat age-related immune decline. New research shows rapamycin protects human T cells from DNA damage in lab tests and in older adults. This drug targets the mTOR enzyme, which becomes more active with age. The findings suggest rapamycin could have broader applications in areas involving DNA damage, such as healthy aging and radiation exposure.
