The lab is interested in discovery of novel molecular and cellular pathways regulating key steps of T cell-mediated tissue-focused immune responses in antitumor immunity and autoimmunity. Such studies will shed new light on immunotherapy for cancer and autoimmune diseases.
Discovery of novel targets in tumor associated immune cells for improving T cell-mediated immunotherapy of cancer.
We are interested in discovering new targets for immunotherapy of cancer through studying the molecular basis underlying effective antitumor T cell immune responses in human and mice. We have found that IL-33R is up-regulated by T-bet and Eomes and 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. Although IL-33 and other cytokines such as IL-12 and IL-2 can inhibit tumor progression in mice, the cytokine-based approach has only achieved modest and transient antitumor effects in human. Therefore, another interest of ours is to understand what are the “brakes” that limit an otherwise successful cancer immunotherapy by cytokines. Our recent 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, we are interested in translating these new findings to the clinical setting, which should greatly benefit cancer patients.
Regulation of stress-triggered molecular responses in T cells in autoimmunity and cancer immunity.
ROS are important for T cells both as a second messenger and as a key inflammatory mediator within the cancer microenvironment and inflamed tissues. The molecular mechanisms underlying T cell responsiveness to ROS is unclear. In addition, how ROS shapes T-cell-mediated immune responses in vivo and how T cells adapt to high levels of ROS in inflamed tissues are largely unknown. We have recently found that ROS homeostasis in T cells is regulated by autophagy. This leads to our current interest in defining the role of autophagy in regulating ROS in T cells. We are also interested in studying the transcriptional factors induced by ROS in T cells as well as innate cells. Our current interest is to delineate key transcription factors in response to ROS in T cells and further understand how these transcription factors regulate T cell-mediated autoimmune responses and antitumor immune responses.
Autophagy is a critical intracellular process regulating T cell signaling, metabolism, clonal expanision and fate decision. Induction of autophagy is an important T cell response to changes of extracellular environments. Our lab has an established interest in understanding how autophagy is involved in physioloigcal and pathological T cell-mediated immune functions. Mechanistic studies of the autophagy regulated molecular network in T cells provide new insights to T cell Biology and immune related diseases.
