David H. Raulet PhD

David Raulet is an immunologist and cancer researcher who focuses on the role of cytotoxic lymphocytes, including NK cells and T cells, in destroying tumor cells. He is known for defining mechanisms of cancer cell recognition by NK cells; how MHC and MHC-like molecules determine NK cell inhibition, activation and education; intrinsic T cell recognition of MHC molecules; and regulated TCR gene rearrangement.

Raulet was born in Buffalo, NY, and grew up in several locations on the east coast and Michigan. He graduated from the University of Michigan with a degree in Microbiology, and from MIT in 1982, with a PhD in Biology. He was a postdoctoral fellow in the Department of Pathology at the University of Pennsylvania School of Medicine. He joined the faculty in the Department of Biology at MIT in 1983 and moved to the Department of Molecular and Cell Biology at the University of California, Berkeley, in 1991. He received the William B. Coley Award for Distinguished Research in Basic and Tumor Immunology in 2002. He is a member of the National Academy of Sciences.

David Raulet's research addresses the specificity of natural killer (NK) cells and T cells, and mechanisms that enable immune cells to detect transformed and infected cells. His current research addresses mechanisms of NK cell activation, inhibition and desensitization, and approaches to manipulate these mechanisms for immunotherapy of cancer. He identified ligands for the NKG2D activating receptor and provided key evidence that this receptor has a central role in immune surveillance of cancer. He defined signals including genotoxic stress, the integrated stress response and hyperproliferation that regulate the sensitivity of cells to elimination by NK cells.
