Sue Straley's lab studied the plague bacterium Yersinia pestis. 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.
A second project in Dr. Straley's lab grew out of the need to identify Yersinia pestis surface antigens against which antibodies can provide protection against plague. These studies led to the discovery of trimeric surface proteins called YadB and YadC. YadC is a candidate for inclusion in an improved plague vaccine, because mice that are vaccinated with YadC are protected against plague.
These studies revealed key steps that are crucial to the development of devastating disease and thus will identify possible ways to prevent and treat plague as well as other important bacterial infections.
