| Research Abstract |
We analyzed the effect and the mechanisms of the cytotoxicity of the peripheral blood (PB) and the cord blood (CB) NK cells against pediatric leukemia and solid tumors. If donor KIR (killer cell Ig-like receptor) ligand is not present in the tumor cells, alloreactivity against the recipients' tumor cells is increased in MLL rearranged acute lymphoblastic leukemia and T-cell acute lymphoblastic leukemia. Therefore the graft versus tumor effect against these malignancies could be considerably expected if the KIR ligand incompatible donor is selected for CBT.
