T cells redirected for universal cytokine-mediated killing
Also known as: fourth-generation CAR-T cells, TRUCK
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Fourth-generation CAR-T cells, known as T cells redirected for universal cytokine-mediated killing, demonstrated the feasibility of localized immune modulation through activation-induced IL-12 release, and this concept has been extended to various cytokines.

This approach requires engineered CAR-T cells and a cytokine-release design coupled to activation. Manufacturing complexity is explicitly noted as a translation constraint.; requires engineered CAR-T cells with activation-induced cytokine release; risks of uncontrolled cytokine activation; manufacturing complexity
The abstract does not claim that TRUCKs fully solve safety or translation problems. Risks of uncontrolled cytokine activation and manufacturing complexity remain.; early stage of clinical application; safety and clinical translation limitations
