Abstract

Clinical Review for Basic Researchers: The available clinical evidence supporting the role of NK cells, and T lymphocytes, in killing tumor cells in haematological malignancies, focusing on strategies optimizing these cells in clinical practice. The identification of an anti-tumor effect displayed by cells of innate immunity has opened new scenarios, not only in the field of allo-HSCT but also for nontransplanted patients with hematological malignancies or solid tumors. Donor-derived NK cells have been shown to contribute to the eradication of malignant cells after allo-HSCT, when recipients lack ligands for their inhibitory receptors. These alloreactive donor NK cells can also kill recipient APCs and CTLs, thus preventing the occurrence of GvHD and graft rejection. The role of activating receptors on the capacity of NK cells to kill leukemia targets has become evident in the last years. The adoptive infusion of ex vivo-activated NK cells has been investigated recently in Phase I/II trials on patients with hematological malignancies and solid tumors, with promising results. T lymphocytes are also able to display anti-tumor activitythis providing the biological rationale for Phase I/II trials in lymphoproliferative disorders and solid tumors. Aminobisphosphonates are clinically available compounds able to boost T cell function. As T cells do not cause GvHD, they could also be transduced with tumor-associated chimeric antigen receptors and safely infused in allo-HSCT recipients. Basic aspects of innate immunity relevant to the field will be covered by a companion review article.
