What this research studies

If you are a cancer patient who develops heart inflammation after immunotherapy, this project will analyze heart tissue and blood samples to find the immune cells responsible. Researchers will use single-cell RNA sequencing and T cell receptor sequencing to map which T cells expand in the heart and whether those same T cells appear in blood. They will compare samples from people with immune-related myocarditis to controls to pinpoint specific T cell clonotypes and molecular signals. The goal is to discover biomarkers that could warn clinicians earlier or guide treatments that protect the heart without stopping cancer therapy.

Who could benefit from this research

Good fit: Ideal candidates are cancer patients who are receiving or have received immune checkpoint inhibitors and who develop or are at risk for myocarditis and can provide blood samples and/or consent to tissue analysis.

Not a fit: People not treated with immune checkpoint drugs or whose heart inflammation is due to non-immune causes are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the work could allow earlier detection or more targeted treatment of immune-related myocarditis so patients can stay safer on cancer immunotherapy.

How similar studies have performed: Early single-cell and TCR sequencing studies have identified expanded T cells in immune-related myocarditis, but clear, validated predictive biomarkers are not yet established.
