Abstract
NK cells are defective in acute myeloid leukemia (AML) at diagnosis. Here, we studied the kinetic of expression of the major activating and inhibitory receptors of NK, CD8 T, and γδ T cells in patients undergoing chemotherapy (CT) for the treatment of AML (n = 29). We showed that NK cells are the main affected population at diagnosis and that expression of activating receptors is partially restored within a few weeks after CT. CD8 T cells and γδ T cells are only weakly affected at diagnosis. Killer cell immunoglobulin-like receptor expression by NK cells, but not NKG2A and CD85j, was downregulated. Interestingly, the development of NK cells appeared altered as the most immature CD56bright NK cells were seriously underrepresented. Finally, we showed that NK cell functions were only partially restored 6 weeks after CT as degranulation capabilities of NK cells recovered, whereas cytokine production remained low. Our data point out NK cells as antitumor effectors peculiarly hampered by leukemic cells. This study may indicate a timeline when NK-mediated therapies or other immunotherapies could be performed, particularly for patients excluded of hematopoietic stem cell transplantation.

Abstract
Cellular immunotherapy has been widely accepted as a new powerful modality of cancer treatment. The last 2 decades have seen impressive results in its application against haemato-oncologic malignancies, melanomas and prostate carcinoma. Cellular immunotherapy has since found applicability beyond cancer into autoimmunity and continues to expand in its clinical applicability. The discovery that stem cells have the ability to differentiate into more mature cell types, like neurones and myocardium, has focused research on using exogenous cells to repair damaged tissues. This led to numerous clinical trials using stem cells in myocardial infarction, cardiomyopathy and spinal cord damage. Results have ranged from modest to significant clinical outcomes with continuing debate on the exact process of regeneration achieved. The intertwining between cell therapy and transfusion medicine now includes research on progenitor cells for the production of mature red cells. It is also clear that cell therapy has enabled an improved understanding of the pathogenesis and clinical course of many diseases, while perhaps its role in regenerative medicine is most enticing. However, the critical role of manufacturing in terms of cost, complexity, reproducibility, and regulatory matters remains a central issue in the consideration of whether cell therapy has met all of its promise.

Abstract
Immunotherapy for leukemia is a promising targeted strategy to eradicate residual leukemic cells after standard therapy, in order to prevent relapse and to prolong the survival of leukemia patients. However, effective anti-leukemia immune responses are hampered by the weak immunogenicity of leukemic cells. Therefore, much effort is made to identify agents that could increase the immunogenicity of leukemic cells and activate the immune system. Synthetic agonists of Toll-like receptor (TLR)7 and TLR8 are already in use as anticancer treatment, because of their ability to activate several immune pathways simultaneously, resulting in effective antitumor immunity. However, for leukemic cells little is known about the expression of TLR7/8 and the direct effects of their agonists. We hypothesized that TLR7/8 agonist treatment of human acute myeloid leukemia (AML) cells would lead to an increased immunogenicity of AML cells. We observed expression of TLR7 and TLR8 in primary human AML cells and AML cell lines. Passive pulsing of primary AML cells with the TLR7/8 agonist R-848 resulted in increased expression of MHC molecules, production of proinflammatory cytokines, and enhanced allogeneic naïve T cell-stimulatory capacity. These effects were absent or suboptimal if R-848 was administered intracellularly by electroporation. Furthermore, when AML cells were cocultured with allogeneic PBMC in the presence of R-848, interferon (IFN)-gamma was produced by allogeneic NK and NKT cells and AML cells were killed. In conclusion, the immunostimulatory effect of the TLR7/8 agonist R-848 on human AML cells could prove useful for the design of TLR-based immunotherapy for leukemia.

Abstract
Human natural killer (NK) and gamma delta (gammadelta) T cells are potent effectors involved in the destruction of abnormal cells. Accumulating clinical and experimental data point towards a key role for NK cells and gammadelta T cells in the control of most, if not all, haematological malignancies. This review focuses on the alterations in these effector cells found in patients with haematological malignancies, which might explain an escape from innate immune surveillance. We discuss new anti-cancer drugs that target these effector cells indirectly or directly. Finally, we review future strategies that offer the possibility of enhancing the effector functions of NK and gammadelta T cells against haematological malignancies.

Acute myeloid leukemic cell lines loaded with synthetic dsRNA trigger IFN-gamma secretion by human NK cells. Leuk Res 2008; 33:539-46. [PMID: 18845337 DOI: 10.1016/j.leukres.2008.08.020] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2008] [Revised: 07/17/2008] [Accepted: 08/26/2008] [Indexed: 11/23/2022]
Abstract
Natural killer (NK) cells are key players of innate immunity. Besides their major cytotoxic function, NK cells can also produce inflammatory cytokines such as interferon (IFN)-gamma. In this way, NK cells can shape adaptive immune responses through activation of dendritic cells (DC), thereby promoting the bidirectional cross-talk between NK cells and DC. Including this helper function of NK cells in cancer vaccination might be important for the induction of effective T cell responses. Here, we explored the capacity of purified human NK cells to produce IFN-gamma upon two-signal stimulation using different types of acute myeloid leukemia (AML) cells and type I IFN. Based on our previous findings that AML cells produce IFN-alpha upon electroporation with the synthetic double-stranded (ds)RNA polyriboinosinic polyribocytidylic acid (poly(I:C)), we hypothesized that dsRNA-loaded tumor cells provide both signals to elicit an NK cell-driven IFN-gamma production. Our results show that in vitro, NK cells become strong IFN-gamma-secreting cells upon stimulation with specific AML cells and IFN-alpha, with a variable responsiveness against different AML cell lines. Importantly, loading of AML cells with poly(I:C) is an elegant method to provide NK cells with both signals, a feature that could have important clinical implications because it obviates the side effects of systemic cytokine administration. Moreover, in addition to our previous findings that DC become activated upon phagocytosis of poly(I:C)-electroporated AML cells, these data strongly encourage future research on the potential of dsRNA-transfected AML cells and their effect to favor NK-DC cross-talk for the design of leukemia vaccines.

Abstract
Abstract
At the frontier between innate and adaptive immunity, dendritic cells (DCs) secrete numerous cytokines and express costimulatory molecules that initiate or enhance natural killer (NK) and T-lymphocyte responses. NK cells also regulate DC physiology by killing immature DCs (iDCs), thus limiting inflammation and inappropriate T-lymphocyte tolerization. In a previous study, we have reported that NK cells from acute myeloid leukemia patients (AML-NK cells) have deficient natural cytotoxicity receptor (NCR) expression. Herein, we analyzed the consequences of such a defect regarding the regulatory role of AML-NK cells in DC physiology. We show that NK cells display poor cytolytic capacities against DCs derived from healthy donor monocytes or derived from autologous leukemic blasts. These data point to a novel defect in the regulation of adaptive immune responses initiated by DCs in AML patients. This may lead to specific T-lymphocyte tolerization by spontaneous or ex vivo expanded iDCs expressing leukemia-derived antigens. (Blood. 2005;106: 2186-2188)

Abstract
HM1.24 antigen is preferentially overexpressed in multiple myeloma (MM) cells but not in normal cells. To explore the potential of HM1.24 as a target for cellular immunotherapy, we selected 4 HM1.24-derived peptides that possess binding motifs for HLA-A2 or HLA-A24 by using 2 computer-based algorithms. The ability of these peptides to generate cytotoxic T lymphocytes (CTLs) was examined in 20 healthy donors and 6 patients with MM by a reverse immunologic approach. Dendritic cells (DCs) were induced from peripheral-blood mononuclear cells of healthy donors or peripheral-blood stem-cell (PBSC) harvests from patients with MM, and autologous CD8(+) T cells were stimulated with HM1.24 peptide-pulsed DCs. Both interferon-gamma-producing and cytotoxic responses were observed after stimulation with either HM1.24-126 or HM1.24-165 peptides in HLA-A2 or HLA-A24 individuals. The peptide-specific recognition of these CTLs was further confirmed by tetramer assay and cold target inhibition assay. Importantly, HM1.24-specific CTLs were also induced from PBSC harvests from patients with MM and these CTLs were able to kill MM cells in an HLA-restricted manner. These results indicate the existence of functional DCs and HM1.24-specific CTL precursors within PBSC harvests and provide the basis for cellular immunotherapy in combination with autologous PBSC transplantation in MM.
