Distinctly different from T cell receptors, NK cell receptors are germline-encoded and hard-wired receptors without a requirement for V(D)J recombination. 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. Clinical-scale derivation of natural killer cells from human pluripotent stem cells for cancer therapy. 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. Imai C, Iwamoto S, Campana D. Genetic modification of primary natural killer cells overcomes inhibitory signals and induces specific killing of leukemic cells.

Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. 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]. The antigen recognition domain usually consists of a single-chain fragment (scFV) molecule derived from a monoclonal antibody, and nanobody-based constructs have been used in limited studies to date [72].

Autologous peripheral blood stem cell transplantation and adoptive immunotherapy with activated natural killer cells in the immediate posttransplant period. Use of chimeric antigen receptor NK-92 cells to target mesothelin in ovarian cancer. 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].

NK Cells of the Lung Br J Haematol. For instance, in the use of CD19-modified K562 to propagate NK cells, the contamination was assessed by flow cytometry detection of surface expression of the NK cell endogenous molecule CD32 and the K562 transgene CD19 to distinguish NK cells from the feeder cells [140]. NK cell dysfunction via altered activating receptor expression or tumor downregulation of NK cell receptor ligands is a common method of tumor immune escape. For example, the absence of NKG2D and other NCR ligands on leukemic blasts allows them to escape NK cell surveillance [86, 87]. 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]. The integration and balance of the activating and inhibitory signals from the ligand/receptor interactions dictates the status of NK cell activation. ErbB2/HER2-specific NK cells for targeted therapy of glioblastoma. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy.
