CNDO-109-NK cells were found well tolerated without occurrence of dose-limiting toxicities [89]. 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]. Tang X, et al. It has been proposed that CAR-NK cells may be able to be combined with T cell-based therapies for solid tumors [77]. BMC Cancer. Cancer Res. On the other hand, it has limited viability support and can trigger proliferative arrest and apoptosis of NK cells at higher dosage (50ng/mL) [118]. Sakamoto N, et al. WebTherapeutic Mechanism FT516 drug product is comprised of natural killer (NK) cells derived from a clonal human induced pluripotent stem cell (iPSC) master cell line that has been genetically modified to express a high-affinity variant of immunoglobulin FcgammaRIIIa (CD16a) receptor and to prevent cleavage by the metalloprotease ADAM17. Ojo EO, et al. Liu E, et al. Bone marrow is considered to be the primary site of NK development. INTRODUCTION Cordyceps is the composite of a genus of fungus that grows on the larva of insects. But cancer cells can make themselves invisible, making it much more difficult for NK cells to find them and do their job. J Exp Med. Interleukin (IL)-2 (IL-2) is one of the first and most important cytokines used for NK maintenance and is integral for NK cell survival. 2019;30(3):10220. Necrotic core even the name sounds creepy. To date, more than 350 Cordyceps-related species have been found worldwide based on fungus and/or insect host. They patrol our bodies for abnormal cells like cancer and destroy them. CAR-NK cells are known to be effective against hematological malignancies, and a growing number of preclinical findings indicate that they have Mol Immunol. Current preclinical development of NK cell-based therapy was largely inspired by early clinical studies. Cancer Immunol Immunother. J Immunother Cancer. Most NK cells in the blood are CD56dim, whereas the CD56bright subset only represents less than 15% of total circulating NK cells [17]. Front Immunol.

Generation of off-the-shelf natural killer cells from peripheral blood cell-derived induced pluripotent stem cells. Wang et al. However, the therapeutic efficacy is generally low in established solid tumors. This TriKE design (GTB-3550) is currently in clinical trial for treating high-risk hematological malignancies (NCT03214666). Cookies policy. In the clinical setting, each batch requires validation, which results in additional lag time before a patient receives infusion. Perform PBMCs apheresis from the patient and isolate NK cells, transfect the NK cells with Claudin6 targeting CAR, amplify the number of transfected NK cells as Article It is currently believed that the success of adoptive transfer requires the creation of a lymphopenic environment to provide a niche for donor cells to survive and proliferate. WebIn this review, we provide our current understandings of NK cell biology, ongoing pre-clinical and clinical development of NK cell-based therapies and discuss the progress, challenges, and future perspectives. Despite the immunosuppressive environment of solid tumors, NK cell activity/infiltration has been correlated with improved prognoses in humans. Hammer Q, et al. Cytotherapy. Eur J Cancer.

The relative proportion of CD56bright and CD56dim NK cells in tissues can be very different from that observed in the peripheral blood [17]. Phase 1 clinical trial using mbIL21 ex vivo-expanded donor-derived NK cells after haploidentical transplantation. IL-2 was used to induce lymphokine-activated killer (LAK) cells, a heterogeneous population of cells consisting primarily of NK, NKT, and T cell for autologous killer cell-based cancer therapy decades ago [115]. Felices M, et al. Notably, many tissue-resident NK subsets are now shown to be phenotypically and functionally distinct from conventional peripheral blood NK cells [20]. 2018; 23(2): 181192. Membrane-bound IL-21 promotes sustained ex vivo proliferation of human natural killer cells. 2018;65:38-48.e1. Kim EK, et al. 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. Lee SJ, et al.

All authors gave consent for publication of the manuscript. 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 PubMed Central The BiKEs or TrikEs are composed of two or three linked single-chain antibody variable fragments of different antigen specificities [79]. In most pre-clinical studies, lentiviral or retroviral-based transduction was used to achieve stable and sustained CAR expression in NK cells. Huang Y, et al. As the activation and expansion methods are improving, it is becoming possible to prepare increasingly higher dosages of NK cells for adoptive transfer from a single-donor phlebotomy. Rubnitz JE, et al. In summary, NK cells are functional in tumor surveillance and can be manipulated by artificial activation techniques to present a highly effective anticancer tool against hematopoietic malignancies and, dependent on successful further rearming and mobilization, against solid tumors in the future. The signaling domains of CAR-NK cells are very similar to those in CAR-T cells, typically composed of the fusion of CD3 with one or two TCR co-stimulatory molecule (s), such as CD28, 4-1BB, 2B4, DNAM1, and NKG2D. Cancer Immunol Immunother. 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]. In the last years, natural killer (NK) cell-based immunotherapy has emerged as a promising therapeutic approach for solid tumors and hematological malignancies. 2017;23(2):489502. Chabannon C, et al.

Multifunctional natural killer cell engagers targeting NKp46 trigger protective tumor immunity. Dhar P, Wu JD. They have the ability to target and destroy tumor cells without prior sensitization, via activation of NK cell-activating receptors 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. Veluchamy JP, et al. Jennifer Wu helped in conception and design. The success has encouraged many ongoing clinical investigations of NK cell-based cancer therapy alone or in combination with other regimes. Rosario M, et al. WebImmune regulation has revolutionized cancer treatment with the introduction of T-cell-targeted immune checkpoint inhibitors (ICIs). Tumor-primed human natural killer cells lyse NK-resistant tumor targets: evidence of a two-stage process in resting NK cell activation. CAR-engineered iPSC-NK cells already have demonstrated effectiveness in targeting human tumors in preclinical studies [41]. reported that a CD16/IL-15/CD33 TriKE not only enhances NK-mediated immunity against CD33+ targets, but also promotes the in vivo persistence, activation, and survival of NK cells by delivering IL-15 [80]. Nat Rev Mol Cell Biol. With the new tools of iPSC-NK and genetic engineering approach as well as new understandings of NK cell biology, it is the time to re-explore the therapeutic potentials of NK cells. In the last 3 decades, NK cells have been utilized to harness A novel CD7 chimeric antigen receptor-modified NK-92MI cell line targeting T-cell acute lymphoblastic leukemia. The presence of autologous feeder cells (typically CD3-depleted PBMCs) in culture additionally facilitates NK expansion [124]. Although lethal irradiation of feeder cells before use is required, for safety concern, the residual contamination of feeder cells should be assessed. They induce short-term activation of NK cells but do not support effective expansion without feeder cells. 2016;1441:34761. Natural killer (NK) cell is a specialized immune effector cell type that plays a critical role in immune activation against abnormal cells. There are also many ongoing clinical trials to evaluate the safety and efficacy of tumor-targeting CAR-NK cells, including using HER2-specific CAR-NK cell to treat advanced or metastatic HER2-expressing solid tumors (NCT04319757), ROBO1-specific CAR-NK cell to treat a broad spectrum of solid tumors (NCT03940820), and MUC1-specific CAR-pNK to treat patients with MUC1-positive relapsed or refractory solid tumor (NCT02839954).
