Cytotoxic cells, including natural killer (NK) cells and cytotoxic T cells, recognize and kill infected and transformed cells. Our laboratory investigates mechanisms of recognition of cancer cells and infected cells by natural killer cells and T cells. Furthermore we investigate mechanisms by which tumors and infectious agents naturally activate or inhibit productive responses by cytotoxic cells, or desensitize the cells by inducing anergy. Our aim is to harness these findings to improve existing immunotherapies for cancer and design new ones. We have employed our understanding of NK recognition, activation and inhibition to establish therapy combinations that super-activate NK cells, while at the same time preventing desensitization and inhibition of the cells.  These combinations show promise as new therapies for cancers that are refractory to existing immunotherapies.

Congratulations to our former colleague, Jim Allison, for his Nobel Prize in Medicine and Physiology— given for his work on cancer immunotherapy at UC Berkeley in the 1990's! We collaborated then to show that CD28 is the constimulatory molecule for T cells. Proof that basic research in animal models transforms human health! See the press release here
