Discover and Develop Novel Checkpoint Inhibitors
PD-1 is a critical inhibitory checkpoint for T cells, and antibodies that block its signaling in turn promote the immune-mediated clearance of malignant cells. Unfortunately, current anti-PD-1 therapeutic agents benefit only a small fraction of patients. Thus, the need to develop additional additional therapeutics targets remains urgent.
Making use of high-resolution proteomic approaches, we have uncovered targetable signaling proteins downstream of PD-1, as well as novel checkpoints that are highly expressed on tumor-infiltrating lymphocytes. In accordance with these discoveries, our current goal is to further develop our understanding of the biology of these proteins, and to confirm their value as potential therapeutic targets.
