P33. NK-92 cellular immunotherapy as an alternative to donor derived peripheral blood NK cells

Infusions with cytokine-activated NK cells obtained from blood of MHC mismatched donors have shown some promising results especially in patients with myeloid leukaemia. There is also indirect evidence that infusions of NK cells as part of a stem cell transplant result in lower relapse rates post-transplant when donor and recipient are mismatched for KIR receptors on NK cells.
