  • Patent number: 11230699
    Abstract: Provided are genetically modified NK cells expressing a chimeric antigen receptor targeting an EGFR superfamily receptor. The CAR can comprise an intracellular domain of Fc?RI? and further recombinant proteins expressed by the genetically modified NK cells are CD16, autocrine growth stimulating cytokines, and optionally one of IL-12, a TGF-beta trap, or a homing receptor. Also described are methods for treating a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer, comprising administering to the patient the genetically modified NK cells.

  • Publication number: 20220017594
    Abstract: Provided herein are populations of IL2 Dependent haNK® cells, which express a high affinity CD16 but does not express IL-2. These cells maintain stable expression of Fc receptor CD16 while retaining cytotoxicity. In some embodiments, the expression level of CD16 decreases no more than 20% when the cells are activated as compared to expression level of CD16 on the cells before activation. Compositions and kits comprising the cells, and methods of making and using the IL2 Dependent haNK® cells are also provided.

  • Publication number: 20210347850
    Abstract: Recombinant NK cells, and especially recombinant NK-92 cells express a chimeric antigen receptor (CAR) having an intracellular domain of Fc?RI?. Notably, CAR constructs with an intracellular domain of Fc?RI? had a substantially prolonged duration of expression and significantly extended cytotoxicity over time. The CAR may be expressed from RNA and DNA, preferably as a tricistronic construct that further encodes CD16 and a cytokine to confer autocrine growth support. Advantageously, such constructs also enable high levels of transfection and expression of the recombinant proteins and provide a convenient selection marker to facilitate rapid production of recombinant NK/NK-92 cells.

  • Publication number: 20210293787
    Abstract: Provided herein are compositions and methods for detecting migration of effector cells towards a target cell, and cytotoxicity of the migrated effector cells against the target cells. The effector cells are modified to express a homing or migratory receptor, and the target cells are modified to express the cognate ligand. The methods can be carried out in a Boyden chamber or tranwells with a porous membrane between the wells. The membrane can be coated with an extracellular matrix component to simulate a solid tumor environment.
