Cancers are among the leading causes of death worldwide and account for 8.2 million deaths in 2012 based on the statistical analysis from WHO. Common used therapeutic strategies at present are designed to remove or shrink the tumor mass through surgery or induction of tumor death by nonspecific cytotoxic agents. During the past two decades, due to the better understanding of cancer pathogenesis, targeted therapy and immunotherapy have been extensively developed and utilized in cancer treatment. In principle, immunotherapy aims to generate effective T cell response for direct killing of tumor cells and induce long-term immune surveillance against cancers. The antigen specificity, life span and effector functions of the resultant T cells from immunotherapies may determine their efficacy. Moreover, the inhibitory mechanisms in tumor microenvironment may also influence the efficacy of the cancer immunotherapy. Dr. Huang has profound experiences working on immune cell interactions in the liver microenvironment and also on T-cell engineering and currently is developing immunotherapies for treatment of cancers based on these well-established immunological knowledge and technologies in the laboratory.
Immunotherapy for CHB and malignancies
During chronic viral infections or malignancies, there are usually monoclonal T cell response detected and most of the Ag-specific T cells undergo exhaustion or apoptosis rapidly after activation. T-cell engineering to introduce genes encoding viral or tumor antigen specific T cell receptors (TCRs) with high avidity or chimeric antigen receptors (CARs) with unique Ag recognition bypassing MHC restriction into activated CD8+ T cells for adoptive cell transfer (ACT) for treatment of malignancies or chronic hepatitis B has been developed and proved to elicit significant clinical responses in patients with melanoma or B-cell leukemia or HBV clearance in preclinical mouse model. Up to now, in addition to TCR and CAR genes, genes encoding co-stimulatory molecules to prevent apoptosis or enhance survival, chemokine receptors to promote T-cell homing and Th1 cytokines to induce inflammation have been used in T-cell engineering for ACT. We aim to study how these effector T cells control its lifespan intrinsically upon stimulation of cognate antigen and co-stimulation/co-inhibition in the tumor or liver microenvironment and how T-cell exhaustion is induced in these intratumoral or intrahepatic T cells. We hypothesize that activated T cells would adjust their metabolic status upon encounter with the cognate antigen, proper co-stimulatory signals to facilitate their aerobic glycolysis, protein translation and lipid synthesis, which suppress apoptosis and therefore prolong the life span of the T cells under regular inflammatory condition in secondary lymphoid organs. However, when entering tumor/liver microenvironment and encountering inhibitory mechanisms, the activated T cells no longer maintain their metabolic status and switch on/off certain metabolic regulation, which promotes T-cell exhaustion. We now are investigating the detailed mechanisms responsible for regulating T-cell survival in the tumor/liver and apply the acquired knowledge in T-cell engineering of CAR T cells for treatment of malignancies and chronic HBV infections
Metabolic reprograming of myeloid cells during tumor progression and during inflammation
Myeloid cells have been shown to be involved in regulation of immune system as well as in promotion of tumor angiogenesis and metastasis. Dr. Huang’s lab is currently investigating the metabolic status of myeloid-derived suppressor cells (MDSCs) and inflammatory monocytes/macrophages and expecting to elucidate the underlying mechanisms responsible for the induction and maintenance of these myeloid cells during tumor progression or inflammation, which may benefit the design of therapeutic strategies for treatment of clinical metastatic disease, Dr. Huang’s lab has found that glycolytic pathway played an important role in maintenance of the cell number of MDSCs in tumor-bearing individual. Specific glycolytic enzymes highly up-regulated during tumor progression are under evaluation for their potential as drug targets. The ultimate goal of Dr. Huang’s lab is to develop therapeutic strategies for curing malignancies through combining the modality able to relieve the immunosuppression induced by MDSCs and immunotherapy e.g. cancer vaccines or ACT.
