Research Interest
Our laboratory conducts basic and translational studies related to cancer precision medicine and innate immunity. We have made major contributions to our understanding of the crosstalk between innate immune signals and cancers.
Current studies focus on the molecular mechanism and pathogenesis of cancer diseases regulated by autophagy and innate cellular components, working toward the goal of identifying novel therapeutic targets and strategies for cancer therapy. To verify the molecular mechanism in vivo, we established two in vivo models, humanized mice engrafted with human stem cells and humanized PDX model engrafted with human cancers.
Major Areas of Research
- Crosstalk between innate immune signals and autophagy in cancer diseases
- Basic properties of innate immune cells in tumor microenvironment (TME)
- Functional roles of Toll-like receptors in tumor microenvironment (TME)
- Development of Humanized PDX mice in cancers
