WebAbstract Background AB-101 is a non-engineered, allogeneic, off-the-shelf, cryopreserved cord blood-derived natural killer (NK)-cell therapy in development as a cancer 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. 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 BMC Cancer. Leukemia.

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 ). A chimeric receptor with NKG2D specificity enhances natural killer cell activation and killing of tumor cells. There are a number of ongoing clinical trials for cancer immunotherapy using engineered iPSC-NK cells, which are summarized in the following sections. 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]. Glyostems lead candidate NK cell therapy is currently being tested in a phase 1/2a trial for the treatment of the blood cancer acute myeloid leukemia. 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]. Phillips JH, Lanier LL.

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].

Despite the immunosuppressive environment of solid tumors, NK cell activity/infiltration has been correlated with improved prognoses in humans. 2002;100(4):126573. NK cells are also potent producers of chemokines and cytokines such as interferon gamma (IFN-) and tumor necrosis factor alpha (TNF-) and thereby are essential in modulating adaptive immune responses. 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. New research by Fred Hutchinson Cancer Center molecular biologist Ami Yamamoto in the Cheung Lab, shows that a tumors necrotic core a mass of dying and dead cells previously thought to be inconsequential or perhaps even 2018;51:5561.

Furthermore, NKp46-ANKET increased the number of NK cells at the tumor site, providing effective control of tumor growth in mouse models of solid and invasive Roda JM, et al. However, since 1964, only Cordyceps Parihar and colleagues designed CAR-NK cells expressing the activating receptor NKG2D as the antigen recognition to target human MDSCs. In order to avoid critical side effects, such as GVHD caused by alloreactive T cells [98] or a passenger lymphocyte syndrome caused by donor-derived B cells [99], purification is recommended for allogeneic NK cells before the expansion to restrict contaminating total T cells to less than 15105/Kg.

For example, there is an ongoing phase 2 clinical trial to evaluate the safety and efficacy of human HLA-haploidentical hematopoieticcelltransplantation (HCT) followed by an early, post-transplant infusion of donor NKcells (NCT02100891). 2017;9(6):1796812. 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.

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]. 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]. With the ongoing effort to improve the treatment response and new methods of generating more feasible clinical scales of NK cells, emerging clinical trials are being designed to evaluate these new modalities and to expand their indications.
