Intracellular pathogens convert macrophages from death traps into hospitable homes. 
Intracellular pathogens - bacteria, parasites and fungi - frequently infect macrophages in addition to other cells.  They turn these deadly cells into harmless hosts to multiply and paralyze immunity.  Understanding the complex mechanisms underlying this phenomenon may have a strong impact to identify new targets belonging to the pathogens but also to the host, thereby allowing the design of new therapeutic strategies.
