“Zombie Cells” Reveal a Hidden Weakness That Could Help Fight Aging

Salk Institute researchers found that senescent human lung cells are unusually vulnerable to ferroptosis.

The enzyme acid ceramidase appears to drive this weakness, making it a promising drug target.

Existing drugs that hit acid ceramidase could potentially be repurposed to clear harmful aging cells.

The approach may help remove “zombie” cells while sparing healthy tissue, supporting healthier aging.
