Workflow Stage Observations
Why this stage exists: The Recognition layer exists to address antigen heterogeneity as a barrier to CAR therapy performance.
Selection basis: Use dual-target and logic-gated CAR designs to counter heterogeneity.
Enriches for: target recognition robustness
Guards against: heterogeneity
Why this stage exists: The Navigation layer exists because cytokines and chemokines shape trafficking and infiltration in solid tumors.
Selection basis: Use hypoxia-responsive and chemokine-responsive circuits to enhance infiltration.
Enriches for: infiltration, trafficking
Guards against: hostile microenvironment
Why this stage exists: The Safety layer exists to reduce severe inflammatory toxicities associated with CAR therapies.
Selection basis: Use inducible safety switches to mitigate IL-6/IL-1β-driven cytokine storm.
Enriches for: safety
Guards against: IL-6/IL-1β-driven cytokine storm, life-threatening toxicities
Why this stage exists: The Persistence layer exists because cytokine support is presented as a way to extend CAR-cell persistence.
Selection basis: Use IL-7/IL-15 support to extend persistence.
Enriches for: persistence, durability
Why this stage exists: The Translation layer exists to extend programmable CAR logic beyond T cells and improve manufacturability and deployment.
Selection basis: Port CAR logic into NK cells and macrophages and use iPSC-derived effectors for scalable, standardized production.
Enriches for: broad clinical integration, scalability, standardization
Preserves downstream axes: clinical translation
Workflow Logic
Objective: Organize programmable CAR-therapy engineering around cytokine and chemokine logic to improve potency, safety, durability, and clinical translation, especially for solid tumors.
Why it works: The framework is presented as effective because cytokines and chemokines are central regulators of trafficking, persistence, and toxicity, so organizing CAR engineering around these signals can address major barriers to solid tumor translation.
Priority logic: The framework prioritizes five layers—Recognition, Navigation, Safety, Persistence, and Translation—to map specific engineering strategies onto the main biological and translational barriers described in the abstract.
Target properties: recognition, navigation, safety, persistence, translation, potency, durability, clinical integration
Target mechanisms: countering heterogeneity, enhancing infiltration, mitigating IL-6/IL-1β-driven cytokine storm, extending persistence, porting CAR logic into NK cells and macrophages, scalable standardized production with iPSC-derived effectors
Target techniques: dual-target CAR design, logic-gated CAR design, hypoxia-responsive circuit design, chemokine-responsive circuit design, inducible safety switch design, cytokine support engineering

These advances reframe cellular immunotherapy as a cytokine-guided, programmable immune ecosystem aimed at potency, safety, durability, and broad clinical integration.
The review introduces a unified five-layer framework of Recognition, Navigation, Safety, Persistence, and Translation to organize CAR engineering through cytokine and chemokine logic.
Cytokines and chemokines shape trafficking, persistence, and toxicity in CAR therapies and therefore demand engineered solutions.
Solid tumor translation of CAR therapies remains limited by antigen escape, hostile microenvironments, and life-threatening toxicities.
