Summary
Chimeric antigen receptor natural killer (CAR-NK) cells exert dual cytotoxic effects against tumor cells through CAR-mediated antigen-specific recognition in concert with the nonspecific cytolytic activity mediated by intrinsic NK receptors.
Usefulness & Problems
Why this is useful
CAR-NK cells are engineered NK cells intended to attack tumor cells using both CAR-mediated antigen recognition and native NK receptor-mediated cytolysis. The review frames them as a strategy to enhance NK-cell antitumor activity in solid tumors.; solid tumor cell therapy; combining antigen-specific targeting with intrinsic NK-cell cytotoxicity

The abstract indicates that clinical deployment depends on allogeneic manufacturing capability and standardized GMP protocols. Engineering for homing and persistence is also described as important.; standardized Good Manufacturing Practice protocols are needed; allogeneic manufacturing remains complex; enhanced homing and persistence are active engineering needs
The abstract states that CAR-NK therapy still faces immunosuppressive tumor microenvironment barriers, manufacturing complexity, and insufficient late-phase clinical evidence. These remain unresolved challenges rather than solved problems.; immunosuppressive tumor microenvironment; complexity of allogeneic manufacturing; need for stronger Phase II/III clinical data; lack of standardized GMP protocols

Ranked Claims
Clinical translation of CAR-NK therapy for solid tumors is limited by the immunosuppressive tumor microenvironment, complexity of allogeneic manufacturing, and the need for improved homing and persistence strategies.
This review critically evaluates the clinical progression of CAR-NK cells specifically against solid tumors, focusing on mechanisms to overcome the immunosuppressive tumor microenvironment (TME), the complexity of allogeneic manufacturing, and the latest engineering strategies for enhanced homing and persistence.
Robust Phase II/III clinical data and standardized GMP protocols are urgently needed to realize the full potential of off-the-shelf allogeneic CAR-NK therapies.
Specifically, we emphasize the urgent need for robust Phase II/III clinical data and standardized Good Manufacturing Practice (GMP) protocols to realize the full potential of off-the-shelf allogeneic CAR-NK therapies.
CAR-NK cells can exert dual cytotoxic effects against tumor cells through CAR-mediated antigen-specific recognition together with intrinsic NK receptor-mediated nonspecific cytolytic activity.
