How an immune signal in brain support cells helps breast cancer spread to the brain
Interrogating Type I Interferon signaling in breast cancer brain metastasis
This project looks at whether a specific immune signal in brain support cells (astrocytes) helps breast cancer cells grow in the brain, aiming to help people with breast cancer that has spread to the brain.

What this research studies
Researchers will use animal models and cell studies to study Type I interferon signaling in astrocytes, the brain cells that surround tumors. They will test how activated interferon in astrocytes may attract immune cells and change the tumor environment to help cancer grow. The team will measure interferon activity at different stages of brain metastasis and use experimental interventions to see if blocking this signal reduces tumor growth in the brain. Findings will be compared with human tumor or tissue samples when available to make results more relevant to patients.
Who could benefit from this research
Good fit: People with breast cancer brain metastases, or those willing to donate tumor tissue or blood samples for research, would be most relevant.
Not a fit: People without breast cancer or without brain metastases are unlikely to gain direct benefit from participation in this preclinical-focused project.
Why it matters
Potential benefit: If successful, this work could identify new targets to prevent or slow breast cancer growth in the brain.
How similar studies have performed: While Type I interferon is known to fight tumors in some settings, the idea that interferon-active astrocytes help brain metastases is relatively new and not yet proven in patients.
