Hematology and Oncology
Hematology is one of the areas in which active interactions and mutual stimulations between clinical medicine and basic science have been producing remarkable progress. We are trying to obtain deeper insights into mechanisms of and develop effective treatments for various hematological diseases, with a motto, “from bedside to bench, from bench to bedside”.

Research and Education
For cure of hematological malignancies and infectious diseases, we are engaged in several research projects of both basic and clinical approaches. Ongoing clinical research projects are as follows: 1. functional analysis of dendritic cells and its application to the immunotherapy of hematological malignancies, and 2. cell-mediated immunotherapy for hematological malignancies including adult T-cell leukemia using hematopietic stem cell transplantation. Basic approaches to hematological and infectious diseases include: 1. functional analysis of phagocytes and other cells involved in the innate and acquired immune systems, 2. analysis of the function and expression of molecules related to iron metabolism, 3. research on the tumorigenesis and pathology of various hematological malignancies including malignant lymphoma, adult T-cell leukemia and MDS/MPD, and 4. elucidation of the mechanisms by which HIV-1 Vif and an antiviral host factor, APOBEC3G, regulate the infectivity of HIV-1. Motivations for these basic research projects have also been arisen during our daily clinical work. We are making efforts to keep pace with rapid advances in hematology, and wish to contribute much to its further progress.
