Listeria monocytogenes is an intracellular pathogen responsible for severe foodborne infections. It can replicate in both phagocytic and non-phagocytic cells, and its ability to invade and survive within host cells is a key factor in its pathogenicity. The pathogen's ability to manipulate host cell signaling pathways and evade the host immune response is also crucial for its survival and persistence within the host. Understanding the mechanisms by which Listeria monocytogenes interacts with host cells is essential for the development of effective therapeutic strategies to combat this pathogen.
