Silencing Immune Alarm Reverses Aging Damage | Science News
Scientists uncover a shocking twist: it’s not the DNA damage itself, but the immune system’s mistaken attack on it that drives rapid aging. A molecule called cGAS, meant to spot viruses, gets fooled by broken DNA and triggers relentless inflammation — shredding tissues and even sabotaging repair efforts. In experiments with fast-aging animals, silencing cGAS reversed brain damage, tissue decay, and even restored fertility. The catch? cGAS also fights viruses, so future treatments must tame its destructive side without weakening immunity. This could revolutionize how we tackle rare genetic…
