Research Interests
Recent approvals of ICBs (anti-CTLA-4, anti-PD-1, and anti-PD-L1) by FDA have rejuvenated the field of cancer immunotherapy. However, accumulating data indicate that only a subset of cancer patients benefit from these treatments, warranting further research endeavors to discover novel targets for cancer interventions. Moreover, severe immune-related adverse events (irAEs) have been observed in a decent proportion of patients treated with ICBs, leading to the early termination of otherwise effective ICBs. Thus, tampering irAEs would unequivocally improve the utilization of ICBs in cancer patients. My research focuses on understanding the mechanisms of immune signaling, metabolic processes, and transcriptional factors that control the maintenance, survival and function of T cells, a central effector cell type in anti-tumor immunity induced by ICBs. For immune signaling, we are interested in IFN-y, IL-17 and IL-7 pathways that orchestrate the formation of effector (TH1 and TH17) and memory T cells (TEM and TCM). For cell metabolic control of T cell differentiation and function, we are interested in the mTOR-HIF1a-glycolysis axis. Information gained from these mechanistic studies could manifest legitimate therapeutic/prophylactic means to mitigate irAEs, and could also reveal potential “metabolic checkpoints” that can be combined with immune checkpoints to boost anti-tumor efficacy. Our experimental approaches include mouse genetics, cellular immunology and biochemistry, as well as murine models of autoimmunity, inflammation, infectious diseases and cancer. Through close collaborations with clinicians at UAB, we will test the translational potentials of our preclinical findings.
