Activating Killer Cells Against Cancer and Viruses

My laboratory studies white blood cells called killer cells that provide protection against viruses and cancer.  Cancer cells and viruses have evolved ways to avoid these killer cells, but new agents called checkpoint inhibitors block these avoidance mechanisms so that one type of killer cell attacks cancer cells more effectively.  We are investigating similar strategies for activating another type of killer cell using superior natural killer cell responses against a common herpesvirus as a model.
