The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua Modell of ...

When scientists discovered how bacteria protect themselves against viral invaders, called phages, in the early 2000s, little did they know they’d stumbled upon a revolutionary tool researchers could ...

Bacteria combat phage infection using antiphage systems and many systems generate nucleotide-derived second messengers upon infection that activate effector proteins to mediate immunity. Phages ...

Collaborating researchers have made a breakthrough discovery regarding the intricate defense systems of bacteriophages (phages)—viruses that can specifically target harmful bacteria without harming ...

Researchers at the University of Southampton have used advanced imaging techniques to uncover how bacteria use a mechanism called Kiwa to defend themselves against phage viruses. Phages are seen as a ...
