Hematopoietic system-specific antigens as targets for cellular immunotherapy of hematological malignancies
1Department of Immunohematology and Blood Transfusion, Leiden University Medical Center, Leiden, The Netherlands.
Allogeneic stem cell transplantation (SCT) is the treatment of choice for many hematological malignancies. Its curative graft-versus-leukemia (GvL) effect is mainly mediated by donor-derived alloreactive T cells. However, if the donor T cells are not selected for their reactivity against leukemic cells, the GvL effect is often associated with graft-versus-host disease (GvHD), a major complication of SCT. Here we summarize our current knowledge on leukemia-associated antigens and discuss strategies to apply minor and major histocompatibility antigens for cellular immunotherapy of hematological malignancies with a low risk of GvHD.
