Plague is highly acute disease, killing animals before they mount an effective immune response. One way the bacteria achieve this is by delivering a set of toxins called Yops into host cells. Contact between Y. pestis and a mammalian cell activates a delivery mechanism that injects virulence proteins called Yops into the cell. The proteins manipulate cellular signaling mechanisms and cause a profound immunosuppression. In collaboration with Drs. Kaplan and Cohen, Dr. Straley's lab identified immunological and molecular targets in host cells for one of the Yops, YopM.
