Hematopoiesis and function of dendritic cells

The main focus of our laboratory is to understand the cellular and molecular events of hematopoiesis of dendritic cells (DCs). DCs are specialized antigen presenting cells and indispensable initiators of immune response. Having a short life, DCs must be constantly replenished through hematopoiesis, a highly organized cellular and molecular process. Downstream of hematopoetic stem cells, a series of progenitors sequentially lose potential to lymphoid and myeloid cells, thereby becoming increasingly restricted to the DC lineage. Such DC hematopoiesis is tightly regulated by extrinsic factors such as cytokines and tissue environment, and intrinsic factors such as transcription factors, both incompletely understood. The capacity to monitor and isolate DCs and their progenitors, in both mice and humans, enables us to study their differentiation potential and gene expression profiles. Using genetic model and patients samples, in combination with in vitro and in vivo models and bioinformatics approaches, we investigate extrinsic and intrinsic factors regulating DC hematopoiesis in both mice and humans, in health and disease.

In particular we are exploring the following areas:

1. Cellular events and transcriptional regulation of DC hematopoiesis in healthy mice and humans.

2. Dysregulation of DC hematopoiesis in leukemia patients.

3. Stromal cell factors driving DC hematopoiesis.

4. How does CNS infection affect differentiation of DCs in the mouse brain?

The long-term goal of our studies is to search for novel ways to manipulate DC development and activity, and to apply the findings to vaccine development and treatment of infectious disease and cancer.
