The battlefield in the war against attaching-and-effacing bacterial pathogens: Monocytes, macrophages and dendritic cells in action

The recent adoption of a unified nomenclature for the mononuclear phagocyte system has already led to the generation of novel strategies for specifically depleting a single subset of phagocytes in the presence of intact lymphoid structures. Herein, we provide a detailed description of how the various types of tissue phagocyte orchestrate the host's defense against enteric bacterial infections. From a bench-to-bedside perspective, we expect that this paradigm will accelerate the development of novel adjuvants and vaccines in human and veterinary microbiology.
