Research Program

The research program in the Liu Laboratory focuses on the dynamic interactions between tumor cells and immune cells in the tumor microenvironment. At the molecular level, we aim at elucidating the mechanisms underlying genetic and epigenetic regulation of expression of tumor suppressors and immune checkpoints, including IRF8, Fas, PD-L1, and OPN, in tumor cells and myeloid cells. At the cellular level, we study tumor cell and myeloid cell interactions with the tumor-specific cytotoxic T lymphocytes (CTLs) in the context of CTL immune suppression. Our long-term goal is to develop molecular target-based immunotherapies to enhance human cancer immune surveillance to treat human cancer.
