PubMed Central The natural cytotoxic receptor NKp46 is also often used to identify mouse and human NK cells in combination with the absence of CD3 expression. Huijskens MJ, et al. NK Cells of the Lung NK cells were identified over four decades ago as lymphocytes with innate ability to lyse tumor cells without the need for prior sensitization [8,9,10]. Table 6 summarizes updated clinical trials of NK cell-based therapy for all solid tumors. Clinical-grade generation of active NK cells from cord blood hematopoietic progenitor cells for immunotherapy using a closed-system culture process. Expression of chimeric receptor CD4zeta by natural killer cells derived from human pluripotent stem cells improves in vitro activity but does not enhance suppression of HIV infection in vivo. observed in CAR NK cell therapy in liquid tumors have not yet been seen in NKG2D and DNAM-1 activating receptors and their ligands in NK-T cell interactions: role in the NK cell-mediated negative regulation of T cell responses. CS1-specific chimeric antigen receptor (CAR)-engineered natural killer cells enhance in vitro and in vivo antitumor activity against human multiple myeloma. Genetically engineered CAR NK cells display selective cytotoxicity against FLT3-positive B-ALL and inhibit in vivo leukemia growth. J Cell Mol Med. 2017;18(9):100415. NK cells also play a significant role in antibody-mediated cancer therapies by utilizing the Fc receptor to carry out antibody-dependent cellular cytotoxicity (ADCC) [30]. CAR-engineered iPSC-NK cells already have demonstrated effectiveness in targeting human tumors in preclinical studies [41]. Lancet. Zhang Q, et al. For instance, the enhancement of the Wnt signaling pathway with GSK3b inhibitor induces definitive hematopoiesis [112, 113] NK cells developed in such conditions had more pronounced inflammatory cytokine production phenotype, whereas Wnt independent NK subsets, similar to primary fetal NK cells, formed a bias for increased cytotoxicity [110].

North J, et al. J Immunol. CAR-engineered NK cells targeting wild-type EGFR and EGFRvIII enhance killing of glioblastoma and patient-derived glioblastoma stem cells. It was hypothesized that once bound to mesothelin-overexpressing tumor cells, furin-mediated cleavage would release CXCL16 from the NRPbody and thereby recruit NK cells to the tumor sites [90]. Blood Transfus. 2019;9(1):6478. The integration and balance of the activating and inhibitory signals from the ligand/receptor interactions dictates the status of NK cell activation. Graft-versus-host disease. Stimulating antibodies is typically used along with irradiated allogeneic PBMC to further promote NK activation and expansion. Exp Hematol.

The linear model proposes that CD56 marks a transition from immature into a more mature status and that immature CD56bright NK cells further differentiate into mature CD56dim populations in human [19, 24]. Natural killer (NK) cell is a specialized immune effector cell type that plays a critical role in immune activation against abnormal cells. Oelsner S, et al. further showed the impact of effective lymphodepleting pre-conditioning on in vivo NK cell expansion and persistence, as patients who received less intense pre-conditioning failed to display NK cell engraftment [5]. 2016;18(5):65363.

Correspondence to NK cells engineered to express a GD2 -specific antigen receptor display built-in ADCC-like activity against tumour cells of neuroectodermal origin. Oelsner S, et al. This successful immunotherapy has led to a more complete view of cancer that now considers not only the cancer cells to be targeted and destroyed but also the immune environment of the cancer cells. 2014;20(5):696704. Cytokines, such as IL15, have been incorporated into killer engagers to further enhance NK cell functions [80]. Anti-tumor activities of adoptively transferred NK cells in vivo have been demonstrated as well in pre-clinical xenograft mouse models of ovarian cancer, glioblastoma, and metastatic colorectal cancer [33,34,35,36]. While the CAR technology seeks to enhance NK cell functions by genetically directing their target specificity, there are active investigations on other strategies to effectively prime NK cells ex vivo or in vivo for optimal anti-tumor functions after their infusion. Targeting immunosuppressive components in the TME to re-invigorate NK functions is also under investigation. Purinergic targeting enhances immunotherapy of CD73(+) solid tumors with piggyBac-engineered chimeric antigen receptor natural killer cells. NK cells possess advantageous characteristics, including non-MHC-restricted recognition, ability to infiltrate The mechanism of CTV-1-mediated NK priming is unclear. In solid tumors, both autologous and allogeneic NK cells have demonstrated potential efficacy. Mu YX, et al.

NK cell-based cancer immunotherapy: from basic biology to clinical development. The NKG2C+NK cells can be found in the circulation of HCMV-seropositive individuals [22]. Jennifer Wu supervised the study. Conversely, tumorigenic cells or virally infected cells have downregulated MHC I expression but upregulated levels of ligands for NK cell activating receptors and thus trigger NK cell activation due to the lack of inhibitory signals and/or the presence of activating signals [11]. Despite the immunosuppressive environment of solid tumors, NK cell activity/infiltration has been correlated with improved prognoses in humans. Phillips JH, Lanier LL.
