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]. Parihar and colleagues designed CAR-NK cells expressing the activating receptor NKG2D as the antigen recognition to target human MDSCs. There are numerous ongoing clinical trials exploring the safety and efficacy of NK-based therapy in combination with other modalities. Phase I/II clinical trials are ongoing to evaluate the safety and efficacy of NK cell combined with nimotuzumab to treat late-stage malignancies (NCT03554889) and of NK cell infusion on patients with advanced malignant tumors following multi-line therapies (NCT03619954). Cord blood NK cells engineered to express IL-15 and a CD19-targeted CAR show long-term persistence and potent antitumor activity. HIGHLIGHTS who: Ming-Yu Lai from the Department of Medical Oncology, Sun Yat-Sen University Cancer Center have published the paper: Comparison of response evaluation criteria in solid tumors and tumor regression grade in evaluating the effect of preoperative systemic therapy of gastric cancer, in the Journal: (JOURNAL) of Heinze, A., et al. However, CAR-T therapy has two major challenges: (i) requirement of a substantiate length of time to generate a therapeutic dose of autologous CAR-T cells which limits its feasibility to treat patients with rapidly progressing diseases; (ii) difficulty to obtain sufficient number of autologous T cells for CAR-T cell generation from heavily pre-treated and often lymphopenic cancer patients [37]. A novel source of NK cells has emerged to circumvent many of the challenges associated with NK cell therapy. CAS 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 Current preclinical development of NK cell-based therapy was largely inspired by early clinical studies. In mouse, the lack of CD3 and the presence of NK1.1 are canonical criterion for distinguishing NK cells. 2006;66(1):51726. Ex vivo-expanded highly purified natural killer cells in combination with temozolomide induce antitumor effects in human glioblastoma cells in vitro.

Notably, many tissue-resident NK subsets are now shown to be phenotypically and functionally distinct from conventional peripheral blood NK cells [20]. However, several studies have shown that intratumoral NK cells can also be associated with increased survival ( 6 Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Cancer Immunol Res. Some clinical efficacy has also been demonstrated for allogeneic as well as autologous NK cell therapy, either alone or in combination with conventional therapies. Crucially, tumor antigen-expressing CAR-NK cell therapy increases anti-tumor activities. Thus, NK cell transfer presents an effective method of fighting cancer. Immunotherapy is a breakthrough in the systemic treatment of malignant tumors, including HCC. Front Immunol. Aiming to generate novel CAR-NK cell-based cancer therapeutics, the consideration of tumor-specific surface antigens and the costimulatory molecules is the In the last 3 decades, NK cells have been utilized to harness Various strategies are being employed to overcome these challenges to improve the efficacy of NK cell-based therapy, such as ex vivo pre-conditioning with cytokines and/or small molecular drugs, engineering an off-the-shelf or iPSC-differentiated chimeric antigen receptor (CAR)-NK. Lanier LL, et al. Smyth MJ, et al. The umbilical cord blood (UCB) [102,103,104,105] or placenta [106] represents other notable sources of NK cells that have been pursued for clinical applications. In addition to cytokine-only strategies, Cichocki and colleagues demonstrated that pharmacologic inhibition of GSK3 kinase with CHIR99021 drives late-stage maturation of ex vivo-expanded human peripheral blood NK cells and enhanced their anti-tumor effector functions both in vitro and in vivo [87].

In allogeneic transfer settings, the concept of KIR and HLA mismatches between donor and recipient was the original strategy aimed at enhancing the activation of donor NK cells to eradicate patients tumor cells. NK cell-based cancer immunotherapy: from basic biology to clinical development. NK cells expressing a chimeric activating receptor eliminate MDSCs and rescue impaired CAR-T cell activity against solid tumors. Romee, R., et al. CAR-engineered iPSC-NK cells already have demonstrated effectiveness in targeting human tumors in preclinical studies [41]. 2019;145(7):193545. 1981;41(11 Pt 1):44205. NK cells are mounted with a repertoire of inhibitory and activating surface receptors (Table 1) [25,26,27,28,29]. Preactivation with IL-12, IL-15, and IL-18 induces CD25 and a functional high-affinity IL-2 receptor on human cytokine-induced memory-like natural killer cells. But what it does in the realm of cancer spread is creepier still. 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. 2018;32(2):52031. It was suggested that induced expression of CD69 on NK cells is important for the cytotoxicity of the CTV-1 tumor cell-activated NK [88]. 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]. 2016;7(19):2776477. Upon ligation, these receptors transmit either inhibitory or activating signals to control NK activation. Mol Immunol. Human iPSC-derived natural killer cells engineered with chimeric antigen receptors enhance anti-tumor activity. J Exp Med, 1982; 155(6): 182341. PubMed Central 2019;7(2):21929. 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.

Leong JW, et al. Blood. 2019;10:2078. 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]. NKG2D and its ligands in cancer. Biol Blood Marrow Transpl. There has been an explosion of NK-based immunotherapies in pre-clinical development and clinical development. NK cells in the tumor microenvironment Conventional roles of NK cells in immunity Detection of aberrant cells by NK cells is determined by the intergradation of J Immunol Res. Although CAR-NK cells hold great promise as a future off-the-shelf drug, there are NK cell-specific challenges, such as potential loss of viability and/or activity with freezethaw process and lack of in vivo persistence. PubMed NKG2D, an activating NK cell receptor, can bind to eight different stress-induced ligands that are naturally expressed on 80% of hematological and solid cancer 2023 BioMed Central Ltd unless otherwise stated. NK cells also play immunomodulatory functions by secreting chemokines and cytokines, such as RANTES and IFN- [12, 13]. Oyer JL, et al. The difficulty to obtain large quantity of NK cells, to expand to clinical scale ex vivo, and to sustain in vivo survival and activity of infused NK cells has encumbered the progress. The Ruggeri group showed that KIR-mismatched alloreactive donor NK cells protected bone marrow-transplanted AML patients from AML relapse while sparing graft versus host diseases (GVHD) [31, 32]. Here, we review advances in current approaches to optimizing the NK cell antitumor response including combination with other immunotherapies, cytokines, checkpoint inhibition, and engineering NK cells with chimeric antigen receptors (CARs) for the treatment of pediatric solid tumors. Transfusion. Immunity. Freshly isolated, activated, or in vitro expanded NK cell populations display phenotypic and functional differences.
