Armored CAR-T Design Agent

The Armored CAR-T Design Agent provides AI-assisted design of next-generation armored CAR-T cells engineered to express cytokines, chemokines, or other enhancing factors. These armored T cells overcome solid tumor challenges including immunosuppressive TME, poor trafficking, and T cell exhaustion, with recent clinical success in lymphoma (IL-18) and ongoing trials with IL-12, IL-15, and IL-7.

When to Use This Skill

• When designing CAR-T cells for solid tumor applications.
• For selecting optimal armoring payloads (cytokines, chemokines).
• To optimize cytokine expression levels and regulation.
• When engineering safety switches for armored constructs.
• For predicting armored CAR-T efficacy and safety profiles.

Core Capabilities

1. Armoring Payload Selection: Choose optimal cytokines for tumor type.

2. Expression Level Optimization: Balance efficacy vs toxicity.

3. Inducible System Design: Engineer regulated expression systems.

4. Safety Switch Integration: Design kill switches and controls.

5. Construct Optimization: Optimize transgene configuration.

6. Efficacy Prediction: Predict enhanced tumor killing.
