My research focuses on splenic hematopoiesis and cellular immunotherapy against cancers. We are studying the heterogeneity of antigen presenting cells in the spleen, particularly, the distinct types of dendritic cells (DC). The microenvironment that supports the development of DC has also been investigated. The current projects run by graduate students have been involved in the generation of multi-specific cytotoxic T lymphocytes (CTLs) and Vγ9Vδ2 T lymphocytes against neuroblastoma. We are also interested in the subpopulation of γδ T lymphocytes that play a crucial role in immune response against tumors.
