Tissue-resident NK cells: development, maturation, and clinical relevance. J Transl Med. Dual targeting of glioblastoma with chimeric antigen receptor-engineered natural killer cells overcomes heterogeneity of target antigen expression and enhances antitumor activity and survival. NK cell progenitors progress through distinct developmental stages and gradually acquire the expression of surface receptors that define NK cell identity such as NK1.1 and CD56 and/or regulate their effector functions such as CD16 and NKp46 [19]. 2017;9(6):1796812. 2013;4:101. Anti-tumor activities of adoptively transferred NK cells in vivo have been demonstrated as well in pre-clinical xenograft mouse models of ovarian cancer, NK cells are a key member of the innate immune system, and while they have some similarities to cytotoxic T lymphocytes (CTLs) in term of killing features, they have an extra intrinsic capability to detect and kill transformed/mutant cells independent of specific antigen recognition processes indicating MHC-unrestricted cytotoxicity done with A novel method to expand large numbers of CD56(+) natural killer cells from a minute fraction of selectively accessed cryopreserved cord blood for immunotherapy after transplantation. With the subcutaneous hypopharyngeal tumor xenograft model, it was shown that CXCR1-expressing CAR-NK cells had enhanced tumor infiltration and tumor control as compared to control CAR-NK cells [54]. Recently, the FDA has approved the investigational new drug (IND) for the use of placenta-expanded NK cells (CYNK-001) against glioblastoma (GBM). The relative proportion of CD56bright and CD56dim NK cells in tissues can be very different from that observed in the peripheral blood [17]. 2013;2(4):27483. 2018;8(6):10839. 2016;7(19):2776477.

Leukemia. Skeate R, et al. This strategy of GSK3 inhibition was used to generate FATE-NK100, which is being evaluated in an ongoing phase 1 clinical trial either as a monotherapy or in combination with monoclonal antibodies in patients with advanced solid tumors (NCT03319459). It yielded a greater than 1000-fold expansion of NK cells after 3weeks of culture [38, 125, 126]. However, since 1964, only Cordyceps Expansion of cytotoxic natural killer cells using irradiated autologous peripheral blood mononuclear cells and anti-CD16 antibody. Compared with cytotoxic T lymphocytes, The donor-derived NK cells have certain limitations mainly because of their variability in functional competence and expansion potential. The purification of NK cells is typically achieved by magnetic depletion of CD3-expressing cells and subsequent enrichment for CD56-expressing cells [100] or by fluorescence-activated cell sorting [101]. Despite decades of work, the ontogeny of NK cells in humans is still not fully elucidated. Aiming to generate novel CAR-NK cell-based cancer therapeutics, the consideration of tumor-specific surface antigens and the costimulatory molecules is the Multifunctional natural killer cell engagers targeting NKp46 trigger protective tumor immunity. 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]. All authors declare no conflict of interest. Leukemia. 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.

Mesothelin is a tumor differentiation antigen that is highly overexpressed in several human cancers including malignant mesothelioma, pancreatic, ovarian, and lung adenocarcinoma [91]. Similar to CAR-T cells, CAR-NK cells are genetically modified to express CARs that recognize a specific antigen uniquely expressed or overexpressed by target cells. 2019;12(1):49. The combination of IL-2/IL-15/IL-21 can support up to eightfold expansion of NK cells [121]. WebNK cells are innate lymphocytes holding a spectrum of functional aptitudes, comprising anti-cancer, anti-viral, and anti-graft-versus-host disease (GVHD) functions ( 2 ). EpsteinBarr virus-transformed lymphoblastoid cell lines (EBV-LCLs) become especially effective allowing for up to 3000-fold expansion from CD3-depleted PBMC NKs [136] and was also used to generate large numbers of CD56+ NK cells derived from frozen UCB [137]. Natural killer cells produce T cell-recruiting chemokines in response to antibody-coated tumor cells. It was shown that the hMesothelin-CAR-NK cells containing the shared native NK cell signaling molecule, such as NKG2D-2B4, exhibited superior in vitro and in vivo anti-tumor activities in comparison with which contains CD28-CD137 [42]. Herein, we will provide an updated overview of the emerging endeavors for developing NK cell-based cancer immunotherapy from pre-clinical conceptual development, clinical grade expansion, and ongoing clinical development. Chimeric antigen receptor (CAR) is an engineered synthetic receptor of CAR-T, which give T cells the ability to recognize tumor antigens in a human leukocyte antigen-independent (HLA-independent) manner and enables them to recognize more extensive target Cell, 2019; 177(7): 17011713. Stem Cell Reports. 2018;6(1):136. NKAML: a pilot study to determine the safety and feasibility of haploidentical natural killer cell transplantation in childhood acute myeloid leukemia. For instance, healthy cells express no or minimal level of ligands for NK cell activating receptors, but express high levels of the major histocompatibility complex class I molecules (MHC I), also known as human leukocyte antigen (HLA), that ligates to the killer immunoglobulin-like (KIR) family inhibitory receptors on NK cells to protect them from NK attack [29]. Lysis of natural killer-resistant fresh solid tumor cells by interleukin 2-activated autologous human peripheral blood lymphocytes. As an alternative to CAR-T cell therapy, CAR-NK cell therapy not only circumvents these challenges but also presents additional major advantages: (i) the ability to use unlimited allogeneic NK source without concern of GVHD [6, 31, 32]; (ii) the potential to generate off-shelf product with NK cell line or iPSC-NK [37,38,39,40,41]; (iii) relatively shortened production time; iv) recognition and killing tumor cells through NK cell native receptors independent of the CAR engineering [42], less likely allowing disease escape through downregulation of the CAR antigens as shown with CAR-T cell therapy [37].
