Researchers tested an engineered enzyme on donated skin tissue and brought its chemical aging markers down to levels typically seen in 31-year-old skin, a separate test on a 75-year-old donor's arteries cut the same damage by more than seventy percent

A paper published on 14 July 2026 in Nature Communications describes an engineered enzyme that reduced a specific chemical marker of tissue aging in donated human skin to levels below what is typically found in the skin of a 31-year-old. In a separate experiment using the abdominal aorta of a 75-year-old donor, the same enzyme cut the marker by more than seventy per cent overnight. The paper, titled “Reversal of protein chemical aging by enzymat…
