TME Immune Profiling Agent

The TME Immune Profiling Agent provides comprehensive tumor microenvironment (TME) immune profiling by integrating multiple data modalities including bulk RNA-seq deconvolution, single-cell transcriptomics, spatial transcriptomics, and multiplex immunofluorescence. It enables biomarker discovery for immunotherapy response and TME-based patient stratification.

When to Use This Skill

• When characterizing immune composition of tumor microenvironment.
• For predicting immunotherapy response from TME profiles.
• To identify immune cell states and functional programs.
• When analyzing spatial organization of immune infiltrates.
• For discovering TME-based biomarkers and therapeutic targets.

Core Capabilities

1. Bulk Deconvolution: Estimate immune cell fractions from bulk RNA-seq.

2. Single-Cell Immune Profiling: Deep characterization of immune populations.

3. Spatial Immune Architecture: Map immune cell locations and neighborhoods.

4. Immune Phenotype Classification: Hot/cold/excluded tumor classification.

5. Functional State Analysis: Exhaustion, activation, memory signatures.

6. Response Prediction: Multi-modal immunotherapy response models.

Workflow

1. Input: Bulk RNA-seq, scRNA-seq, spatial data, or IHC images.

2. Deconvolution: Estimate cell fractions from bulk data.

3. Single-Cell Analysis: Deep immune phenotyping if available.

4. Spatial Mapping: Localize immune populations in tissue.

5. Integration: Combine modalities for comprehensive profile.

6. Classification: Assign TME phenotype (hot/cold/excluded).

7. Output: Immune profiles, visualizations, response predictions.

Special Considerations

1. Reference Panel: Use cancer-type specific references
2. Batch Correction: Normalize across samples/platforms
3. Purity Effects: Account for tumor purity in deconvolution
4. Single-Cell Validation: Validate bulk estimates with scRNA
5. Spatial Context: Bulk loses spatial information
