| Posted: 21 Jul 2022 10:20 AM PDT Macrophages play a central role in our immune response. They can trap and digest invading pathogens.

Research reveals how different organelle systems communicate to activate a more effective anti-bacterial defense mechanism. Successful elimination of specific bacteria in the phago-lysosomal system depends on a signal controlling mitochondria. The yet unknown phago-lysosome-mitochondria crosstalk in macrophages leads to a better understanding of how immune cells work and may identify new intervention points for treating infectious diseases. |
