NKG2D-ACE2 CAR-NK Cell

Generic Name
NKG2D-ACE2 CAR-NK Cell
Drug Type
Biotech

Overview

These cells are prepared as universal off-the-shelf CAR-NK cells from cord blood with NKG2D-ACE2 proteins engineered as part of the CARs; the cell secretes IL-15 and GM-CSF. Chimeric antigen receptors (CARs) are artificial receptors consisting of an antibody-derived antigen binding domain and transmembrane and signaling domains from T-cell receptor signalling moieties. First used with autologous human T cells (CAR-T) as cancer immunotherapies, these receptors are now being engineered onto natural killer (NK) cells due to lower potential for graft-versus-host disease and cytokine release syndrome. The IL-15 superagonist increases the activity of NK cells and improves their target cytotoxicity. The GM-CSF acts as a neutralizer for the CAR-T cell-mediated cytokine release and neurotoxicity. The transmembrane NKG2D and intracellular 2B4 domains are required for optimal NK signalling and subsequent cell-mediated cytotoxicity. The ACE2 is a receptor for SARS-Cov-2, binding to the S-protein of the viral envelope and competitively inhibiting SARS-Cov-2 infection of type II alveolar epithelial cells.
