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

Armoring Payload Selection: Choose optimal cytokines for tumor type.
Expression Level Optimization: Balance efficacy vs toxicity.
Inducible System Design: Engineer regulated expression systems.
Safety Switch Integration: Design kill switches and controls.
Construct Optimization: Optimize transgene configuration.
Efficacy Prediction: Predict enhanced tumor killing.

Armoring Strategies

Cytokine	Mechanism	Clinical Status	Tumor Types
IL-12	Th1 polarization, IFN-gamma	Phase I/II	Solid tumors
IL-15	T/NK persistence	Phase I/II	Hematologic, solid
IL-18	Inflammasome, IFN-gamma	Phase I (promising)	Lymphoma
IL-7	T cell survival	Phase I	Multiple
IL-21	T cell proliferation	Preclinical	Multiple

Kill Switch	iCasp9, HSV-TK, CD20	Safety control
Position	Before/after CAR	Expression balance

Workflow

Input: Target tumor type, TME characteristics, CAR design.
Payload Selection: Rank armoring strategies for tumor context.
Expression Design: Optimize promoter, levels, regulation.
Safety Engineering: Add appropriate control switches.
Construct Assembly: Generate optimized DNA sequence.
Efficacy Prediction: Model enhanced killing and persistence.
Output: Optimized armored CAR construct with annotations.
