Research Interests:
My primary interest is to characterize the function of chemokine receptors in immune response. They play major roles in pathogenesis of many inflammatory disorders by regulating differentiation, activation and migration of hematopoietic cells. We have identified chemokine receptor CXCR4 as a coreceptor for HIV-1 entry. Mice deficient in CXCR4 die perinatally with defects in B-lymphopoiesis and myelopoiesis. Reconstitution of mice with CXCR4-deficient stem cells demonstrates the role of CXCR4 in retaining hematopoietic precursors within the bone marrow microenvironment for proper maturation. We will further elucidate SDF-1/CXCR4 pathway in regulating hematopoiesis including stem cell mobilization, engraftment and plasticity. In addition, I am also interested in cancer immunology and translational research. We are characterizing other chemokine receptors, such as CCR5 and CCR7, which regulate the function of naïve, effector and memory T cells. The overall goal is to understand molecular mechanisms of T cell mediated immune response and develop novel methods for immunotherapy.
Depending on the student's interests, a tutorial in my laboratory would provide experience with molecular biology, cellular immunology, mammalian cell culture, flow cytometry, murine model of human disease. In addition, the tutorial will focus on developing a research project to make fundamental discoveries in basic science and translate the knowledge into clinic.
