Scientists find an immune “false alarm” that may drive rapid aging

Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage.

When broken DNA fragments leak into the wrong part of a cell, an immune sensor called cGAS can mistake them for signs of a viral infection, triggering chronic inflammation and even interfering with DNA repair itself.
