Lesson from hematopoietic stem cell transplantation demonstrated that donor immuno-surveillance system can eradicate tumor cells. This is so-call graft versus tumor(GVT) effect. Antigen presenting cells show peptide from minor antigen rather leukemic specific antigen in the context of major histocompatibility complex. The effector cells composed of CD8 T lymphocyte, CD4 T lymphocyte, natural killer cell and natural killer T cell. Death signal was transmitted from effector cells via granzyme/perforin system and FasL/Fas system, and recently TRAIL system seems most important for GVT effect.
