Scientists discover new part of the immune system

SMRTR summary

Scientists have discovered a new part of the immune system that could be a source of potential antibiotics. The proteasome, normally responsible for recycling proteins, can detect bacterial infections and transform proteins into bacteria-killing weapons, comparable to some established antibiotics in lab tests. This finding transforms our understanding of immune protection and offers a new avenue for developing antibiotics to combat drug-resistant superbugs, which cause over a million deaths annually.
