Bacteria can 'outsmart' programmed cell death

Certain bacteria can override a defence mechanism of the immune system, so called programmed cell death, through inhibition of death effector molecules by their outer membranes components. Shigella bacteria, which cause diarrhoea, ...

How the strep bacterium hides from the immune system

Magnesium deprivation stops pathogen growth

When pathogens invade cells, our body combats them using various methods. Researchers at the University of Basel's Biozentrum have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers ...

Imaging host-pathogen battle for metal

Bacterial pathogens require nutrient metals to survive and cause disease, and hosts try to protect themselves by hiding metals away—a process called "nutritional immunity." Bacteria have evolved multiple strategies for ...
