Scientists Discover Some “Zombie Cells” May Actually Help You Live Longer

A new review says senescent, or “zombie,” cells are not all harmful: some drive inflammation and age-related disease, while others support repair and tissue maintenance.

The authors argue anti-aging therapy should move toward precision targeting instead of broad elimination of all senescent cells.

Selective approaches such as senolytic drugs and targeted immunotherapies, including CAR-T strategies, may better balance benefits and risks.

The findings suggest future treatments should remove harmful senescent cells while preserving the ones that help wound healing, development, and normal tissue function.
