Immune Cells That Defy Aging | Science News

Scientists have uncovered a surprising immune secret behind supercentenarians—people living past 110. A special type of immune cell, CD4 cytotoxic T lymphocytes, appears to multiply and adapt relentlessly with age, helping fight cancer and fend off threats even in extreme old age. Found in higher numbers in the oldest participants, these cells may be key to healthy aging—not just surviving, but thriving well beyond 100. Researchers are now racing to decode exactly how these cells work and whether they can unlock new ways to extend human healthspan.
