Immune Cells That Defy Aging | Science News

Scientists have uncovered a surprising twist in aging: centenarians pack more CD4 CTLs—rare immune “assassin” cells—that surge in number after age 100, actively hunting viruses, inflammation, and cancer. These cells multiply as people grow older, especially in supercentenarians, suggesting an active, self-renewing defense system that may explain their longevity. While experts caution this isn’t yet a full breakthrough, the discovery opens exciting new doors for boosting immune resilience and understanding how to live longer, healthier lives.
