NK cell engagers
Also known as: bispecific/trispecific NK cell engagers, NKCEs
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Key innovations in engineered NK cell therapies-including CAR-NK, cytokine armoring (e.g., IL-15), and bispecific/trispecific NK cell engagers (NKCEs)-are critically evaluated.
Usefulness & Problems

NK cells offer reduced toxicity and off-the-shelf potential relative to CAR-T therapies.
Strategies to enhance homing, infiltration, and durability are discussed for engineered NK cell therapies.
CAR-NK therapy is presented as a paradigm shift in immuno-oncology that is augmented by NKCEs and cytokine armoring.
Future directions in engineered NK therapy include logic-gated CARs, iPSC-derived NK platforms, and combinations with immune checkpoint blockade.
Antigen escape remains a shared limitation of both CAR-T and engineered NK cell therapies.
NK cell-based therapies address safety challenges associated with CAR-T, including reduced CRS and GvHD.
Engineered NK cell therapies face translational barriers from tumor microenvironment immunosuppression, metabolic constraints, and NK cell exhaustion.
