Three gram-negative bacteria within the genus Yersinia are capable of causing debilitating and occasionally fatal infections in humans. Pathogenic Yersinia utilize secreted virulence proteins (Yops) to manipulate and subvert the host response to infection. In particular, it has been demonstrated that Yersinia use the YopJ/P protein to block both intracellular signaling pathways and the induction of pro-survival signals that subsequently results in apoptosis of the infected host macrophage. The goal of our research is to examine how modulation of apoptosis influences the outcome of infection with Yersinia pseudotuberculosis.
