A stronghold in the fight against viruses - new bacterial immune system decoded

International research team describes for the first time the structure and function of the Zorya system

16-Dec-2024 - Bacteria are constantly infected by viruses, so-called phages, which use the bacteria as host cells. However, in the course of evolution, bacteria have developed various strategies to protect themselves from these attacks. Many of these bacterial immunity systems have been known for a long time. ...
