Drugs “reverse” aging in animal experiments

According to a study published in the journal Cell, scientists at the Erasmus University Medical Center in the Netherlands reported that a drug that reverses the characteristics of aging has been successful in animal testing. The drug restores the youthful vitality of older rats, including endurance, fur and even some organs such as the kidney. Researchers are preparing human trials. The method they use is straightforward: selective killing of aging cells. Dr. Peterde Keizer, who led the study, said that people thought he was crazy, and indeed three attempts failed three times, but the fourth showed signs of success. According to the abstract of the paper: the accumulation of unrepairable cell damage limits healthy lifespan, aging cells are thought to impair organ function, and clearing these cells can delay aging. Researchers have developed a compound that recognizes aging cells and induces apoptosis. Tests on experimental mice have shown that this compound can restore its organ viability, demonstrating that targeted treatment of senescent cells is feasible in the event of organ damage, and can effectively restore organ function.
