APOE2 Longevity Gene Boosts Brain DNA Repair, Lowers Alzheimer’s Risk

The gene known as APOE2 shows signs of protecting brain cells as we age by boosting DNA repair and slowing cellular aging, a finding surfaced by lab work on human neurons and supported in mice; researchers see fresh directions for therapies but warn this is a biological insight, not a treatment, and recommend standard brain-healthy...
