• Injection of effector proteins by a type III secretion system (T3SS) is a common infection strategy employed by many important human pathogens, including enteric Escherichia coli, Salmonella, Yersinia, and Shigella, to subvert cell signaling and host responses. In recent years, great advances have been made in understanding how the T3SS effectors function and execute the diverse infection strategies employed by these pathogens. In this review, we focus on effectors that subvert signaling pathways that impact on endosomal trafficking, cell survival, and innate immunity, particularly phagocytosis, nuclear factor-?B (NF-?B), and mitogen-activated protein (MAP) kinase pathways and the inflammasome.
