In the field of cancer immunotherapies, much attention has been devoted towards studying the optimal combination of inhibitory T cell surface receptors that can be targeted with to boost anti-tumor T cell activity. Research in the Riese lab focuses on the study of intracellular negative regulators of T cells that may serve as useful targets in cancer treatment. Specifically, the lab focuses on diacylglycerol kinase ζ (dgkζ), a protein that metabolizes the second messenger diacylglycerol (DAG), serving as an off switch for DAG-regulated signaling, including activation of Ras and PKCq. We have found that T cells deficient in dgkζ demonstrate enhanced T cell activity and tumor clearance, both in subcutaneous tumor models, and orthotopic models that utilize T cells engineered to express chimeric antigen receptors (CARs). Work on the lab focuses both on understanding the molecular changes that result from manipulation of dgkζ in T cells, and on translating the work to eventually permit study in human patients.
