„Elixirul tinereții” ar putea exista? Cercetătorii au observat ceva neașteptat la organele îmbătrânite

Researchers have made a surprising discovery about aging, suggesting a new perspective on the so-called 'fountain of youth'. They found that transplanted organs quickly adjust their biological age to match that of the recipient. Older hearts transplanted into younger patients showed signs of biological rejuvenation, while younger hearts in older bodies aged more rapidly. This study aligns with new research on aging processes and blood factors that may hold answers for longevity. Initial tests on mice showed significant changes in DNA methylation, a key aging marker. Human analysis of heart transplant recipients revealed that important health indicators were closer to the recipient's age. This discovery could change organ allocation practices and research on aging, challenging previous medical assumptions about using older donor hearts for younger patients.
