Donor-derived natural killer cells infused after human leukocyte antigen-haploidentical hematopoietic cell transplantation: a dose-escalation study. 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]. Early clinical trials have demonstrated the overall safety of NK cell infusion, even in the allogeneic setting [4,5,6,7]. WebImmune regulation has revolutionized cancer treatment with the introduction of T-cell-targeted immune checkpoint inhibitors (ICIs). One major immunosuppressive factor in the TME is the metabolite adenosine, whose production is catalyzed in a sequential manner by the ectoenzymes CD39 and CD73 [43]. Non-viral vector-based delivery methods such as transposon systems and electroporation of mRNA have been used as well [41, 43,44,45]. Sci Transl Med. Front Oncol. 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. CAR-NK is one of the approaches in development to overcome this limitation. Beyond directing CAR-NK cytotoxicity against tumor cells by targeting tumor antigens, it has been proposed that CAR-NK cells can be used to eliminate immunosuppressive immune cells in the tumor microenvironment that include myeloid-derived suppressor cells (MDSCs) and M2 tumor-associated macrophages (TAMs) [77, 78]. Due to relatively unsophisticated cues for activation, NK cell has gained significant attention in the field of cancer immunotherapy. NK cell infiltration Cord blood NK cells engineered to express IL-15 and a CD19-targeted CAR show long-term persistence and potent antitumor activity. Science. However, NK92 is a transformed cell line that has limitations associated with its tumorigenic nature, and cytogenetic abnormalities, thus requiring irradiation for clinical use, which limits its life-time activity. The exciting results from Liu et al. Furthermore, IL-2, streptococcus A group, and zoledronate have all been approved for human use. However, NK cell therapy directed against solid tumors is still in early development. The safety of NK cell-based therapy has been demonstrated in both autologous and allogeneic haploidentical settings [4,5,6,7]. Front Immunol. 2020.

The natural cytotoxic receptor NKp46 is also often used to identify mouse and human NK cells in combination with the absence of CD3 expression. Blood. Article Three out of 12 patients had durable complete remissions [89], providing evidence for further clinical evaluation of this approach. Knorr DA, et al. Among these TCR cell co-stimulatory molecules, 4-1BB, DNAM1, 2B4, and NKG2D were also expressed by NK cells as native activating receptors. In pre-clinical studies, various BiKEs and TriKEs have been designed to target a number of tumor antigens: CD19, CD20, and CD33 for hematological cancers, HER2, EGFR, and EpCAM for solid tumors [79]. 2016; 108(5).

However, the exhaustion of T cells or NK cells can lead to the failure of tumor control and limit the complete response and overall efficacy of cancer immunotherapy against solid tumors. Cell, 2019; 177(7): 17011713. 2016;7:105. J Natl Cancer Inst. Chemical stimuli such as Concanavalin A(ConA) [138], Phytohemagglutinin (PHA), and ionomycin [139] were also used in combination with irradiated allogeneic PBMCs to facilitate the activation. Distinct from T cells, there is no master transcriptional factor that controls NK cell development. Although challenges exist, perspectives are enticed by currently approved NK cell-based therapies and emerging pre-clinical and clinical studies. Smyth MJ, et al. Typically, a dose of UCB or placenta donor can be expended to an amount sufficient for one adoptive transfer procedure. 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]. 2016;1441:34761. It remains to be determined how NRPbody will interact with a more complex and realistic immune contexture in the TME which consists of more than NK cells, as CXCL16 was shown in other tumor models to correlate with the infiltration of monocytes and M2-macrophages as well [92, 93].

There are great numbers of clinical trials on NK cell immunotherapy to treat solid tumors. CAS PubMed Central Natural cytotoxic reactivity of mouse lymphoid cells against syngeneic acid allogeneic tumors. Front Immunol. Killer (NK) cell activity against solid tumors. Front Med (Lausanne). Moreover, the CAR-NK cells secrete pro-inflammatory cytokines and chemokines which may improve the infiltration and functions of subsequently infused CAR-T cells in the mouse model [77]. NK cells with KIR2DS2 immunogenotype have a functional activation advantage to efficiently kill glioblastoma and prolong animal survival. The mechanism of CTV-1-mediated NK priming is unclear. 1986;137(9):27359. Jennifer Wu helped in conception and design. Immunity. Due to their innate ability to eliminate tumor cells, NK cell-based immunotherapies against cancer have been investigated for decades. CD19-CAR engineered NK-92 cells are sufficient to overcome NK cell resistance in B-cell malignancies. The conventional linear model suggests that mature NK cells arise from common lymphoid progenitors (CLPs) by progressing through a linear continuum [24]. 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]. The approach of using the modified NK cell line CAR-NK92, which can be easily expanded to large dose, has been in clinical trial. MUC1-specific CAR-pNK therapy presented good safety profile and preliminary efficacy in preventing both tumor relapses and graft versus host disease [151]. 2020;16:7585. Lopez-Soto A, et al. 2019;10:3123. 2018;48(6):110417. Sakamoto N, et al. CAR-NK cell therapy has proven to kill hematological and solid tumor cells in preclinical and clinical trials, demonstrating its potential as an off-the-shelf product with In many studies, IL-2 or IL-15 is supplemented during ex vivo expansion of NK cells and sometimes after NK cell infusion as well [5]. An even greater expansion of NK cells, of over 30,000-fold in a period of 3weeks, was achieved with K562 membrane-bound IL-21 and 4-1BB ligand [127,128,129,130]. J Immunother Cancer. Fehniger TA, et al. This protocol created a possibility to generate a substantially higher number of NK cells from a single dose of peripheral blood [131] and is currently in phase I/II clinical trial (NCT01787474) with expanded haploid-identical NK cells for treating relapsed or refractory AML.

While the majority of investigation of ex vivo NK priming strategies rely on one or more cytokines, some studies indicate that cytokine supplement is not as critical for NK cell priming. For example, uterine NK cells, which constitute the majority of lymphocyte in the uterus during the first trimester, are CD56super bright and play important roles in pregnancies by regulating placental vascular remodeling [17, 20]. 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. 2016;20(7):128794.

Genetic modification of primary natural killer cells overcomes inhibitory signals and induces specific killing of leukemic cells. Expression of IL-15 in NK cells results in rapid enrichment and selective cytotoxicity of gene-modified effectors that carry a tumor-specific antigen receptor. The differences also arise from activation approaches, such as the choice of interleukins, their combinations, type of feeder cells, and some other factors [95,96,97].

Topfer K, et al. 2002;100(4):126573. 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]. Hassan R, Ho M. Mesothelin targeted cancer immunotherapy. Clinicaltrials.gov currently lists over 100 clinical trials of NK cell-based cancer immunotherapy. CAR-NK cells are known to be effective against hematological malignancies, and a growing number of preclinical findings indicate that they have 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]. 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]. Tri-functional NK cell engagers (NKCEs), which crosslink both NKp46 and CD16, have demonstrated superior in vitro and in vivo anti-tumor activities compared to conventional monoclonal antibodies targeting the same antigens [81]. The current in-development BiKEs or TrikEs simultaneously engage with CD16 and tumor antigens, thereby inducing the formation of immune synapses and NK-mediated ADCC [79].
