Researchers at the Indian Institute of Technology (IIT) Bombay discovered a host protein that uses tiny tweezer-like machines to kill germs before they harm the body. The study, led by Professor Anirban Banerjee, found that this protein works like a special operation unit to detect and neutralize threats. When bacteria attack, human cells tag them as a "Red Flag" using a protein called "Ubiquitin." Cells then target the flagged bacteria, tearing apart their surface proteins, similar to piranhas attacking prey. This discovery could help fight antibiotic-resistant bacteria, offering hope for more effective treatments against infections.
