Tumor-Derived Extracellular Vesicle Systems for Immune Suppression, Metastatic Conditioning, and Therapeutic Resistance
Program Code: HEMOREGEN-IMM-004
Division: HEMOREGEN-IMMUNO
Parent Program: HEMOREGEN-721
Former Code: SCF-VIRA-EVCM-0004D
Classification: Tumor Immune Communication and Evasion Platform
Status: Master Foundational Atlas v1.0
EXECUTIVE SUMMARY
The Tumor Immune-Escape EV Atlas maps the extracellular vesicle (EV) communication systems employed by malignant cells to evade immune destruction, establish metastatic competence, remodel host tissues, and suppress adaptive and innate immune responses.
Within PROJECT HEMOREGEN-721, tumor EVs are considered active biological warfare platforms capable of:
- Immune checkpoint propagation
- Cytotoxic T-cell exhaustion
- Regulatory T-cell amplification
- Myeloid reprogramming
- Premetastatic niche formation
- Therapeutic resistance propagation
- Organotropic metastasis conditioning
This atlas establishes the mechanistic foundation for anti-EV immuno-oncology platforms.
