Scientists have identified a crystal-based mechanism where immune proteins instantly cluster to initiate cell death when viruses invade. This ancient defense system, found even in bacteria, may also drive aging-related inflammation through spontaneous activation. The discovery reveals how cells make rapid life-or-death decisions through protein crystallization.

Crystal-Based Cell Defense Mechanism Uncovered

Researchers have discovered a sophisticated immune mechanism where specialized proteins form crystals to trigger immediate cell death when viruses invade, according to a recent study published in eLife. This process enables cells to make rapid life-or-death decisions within minutes of detecting a pathogen, potentially preventing viral spread throughout the body.
