Outline of Final Research Achievements |
In allogeneic stem cell transplantation for advanced childhood acute lymphoblastic leukemia (ALL), it has been suggested that graft-versus-leukemia (GVL) effect eradicates residual disease. In GVL effect, cytotoxic ligands expressed on cytotoxic T-cells (CTLs) and NK cells play an essential role by inducing apoptosis of leukemia cells. In the present study, we confirmed that culture conditions mimicking bone marrow environment induce relative resistance of leukemia cells to chemotherapeutic agents. Of note, we also confirmed that TRAIL, one of cytotoxic ligands, is still active against leukemia cells in the culture conditions mimicking bone marrow environment. These observations suggested that allogeneic stem cell transplantation would be attractive therapeutic modalities against chemo-resistant childhood ALL.
