Bacteria turn a virus’ own weapon against it: Study
Summary
Scientists have discovered that a virus-produced enzyme can cut a bacterial sensor protein and trigger a self-destructing immune response in bacteria. The finding could help improve phage therapies against antibiotic-resistant infections and offers new clues about ancient immune mechanisms shared with humans.
Key Points
- Researchers found that a viral protease can cut a bacterial sensor protein and activate the CBASS immune system.
- CBASS can trigger a self-destruct response in infected bacteria to stop the virus from spreading.
- The discovery may help develop more effective phage therapies against antibiotic-resistant bacteria.
- The pathway studied is related to an immune mechanism found in humans, suggesting deep evolutionary roots.
