Implementation requires engineered CAR-T cells carrying cytokine-arming features. The abstract does not specify the exact cytokine payloads beyond the TRUCK concept.; requires cytokine-armed CAR-T design
The abstract does not state that TRUCKs alone solve antigen heterogeneity, trafficking barriers, or toxicity.
