My research area includes tumor immunology and cancer immuotherapy. We are investigating ways to harness anti-tumor immune functions for clinical application. Our team has pioneered molecular characterization of tumor associated Treg cells (TIM3+ Treg cells), established key transcription factors controlling tumor specific memory stem T cells (Tbet and Eomes), ushered in novel cytokine-based cancer immunotherapy (IL-33 and IL-36), and driven science-based cancer drug development programs. The lab is currently interested in using data science for the discovery of novel molecular and cellular pathways regulating key steps of T cell-mediated tissue-focused immune responses in antitumor immunity and novel cancer immunotherapy.
Discovery of novel targets in tumor associated immune cells for improving T cell-mediated immunotherapy of cancer.
Our basic research is driven by biological Data science aiming at constructing and understanding the cellular and molecular immune networks in the tumor tissues. We are discovering new targets for immunotherapy of cancer through studying the molecular basis underlying effective antitumor T cell immune responses in human cancer.
We have found that the IL-33 receptor is up-regulated in effector Th1 and CD8 T cells. We further established that expression of IL-33 in tumor cells greatly inhibited tumor growth through enhancing the function of CD8 T cells and NK cells and inhibiting MDSC within tumor. Current interest is to explore IL-33 in immunotherapy of cancer and Mode of action by IL-33 class drugs in immune oncology.
Besides positive regulators of antitumor immune responses, we also have keen interest in understanding what are the “brakes” that limit an otherwise successful cancer immunotherapy. Our past work has identified several molecules that have such functions. We discovered that one such “immune brake” TIM-3 is highly expressed in tumor-infiltrating T cells in both human and mouse tumors. Blockade of TIM-3 should significantly improve immunotherapy of cancer. In close collaboration with clinicians and the biotech industry, we are actively involved in translating these new findings to the clinical setting, which should greatly benefit cancer patients.
Adaptive metabolic programing in T cells in autoimmunity and cancer immunity.
Our focus is on two major metabolic regulatory pathways namely Autophagy and the Integrated Stress Response pathway. Our studies have helped establish that these pathways are a critical intracellular process regulating T cell signaling, metabolism, clonal expansion and fate decision. Mechanistic studies of Beclin 1/Atg6 in autophagy and ATF4 in regulating amino acid metabolic reprogramming in T cells generate new insights to T cell Biology and immune related diseases.
