Muscle, blood vessel, and immune cell interactions in ME/CFS muscles

Dissecting myogenic-endothelial-immune interactomes in human ME/CFS skeletal muscles

NIH-funded research Cornell University · NIH-11501140

This project uses detailed single-cell and chromatin tests on muscle biopsies and blood from people with ME/CFS to learn how muscle, vascular, and immune cells might cause severe fatigue.

What this research studies

Researchers will collect new skeletal muscle biopsy and blood samples from people with ME/CFS and matched healthy controls. They will apply single-cell methods including ATAC-seq and related assays to map cell types, gene activity, and chromatin accessibility in muscle tissue. The team will focus on myogenic (muscle), endothelial (blood vessel), and muscle-resident immune cells to characterize their identities and interactions. Results will be compared to metabolic and inflammatory signals to look for biomarkers or targets linked to fatigue.

Who could benefit from this research

Good fit: Ideal participants are adults diagnosed with ME/CFS who can safely undergo a skeletal muscle biopsy and provide blood samples.

Not a fit: People without ME/CFS or those unable or unwilling to have a muscle biopsy are unlikely to receive direct benefit from participating.

Why it matters

Potential benefit: If successful, this work could reveal muscle-based biological signals that lead to better biomarkers and new targets for ME/CFS treatments.

How similar studies have performed: Single-cell and chromatin-accessibility methods have revealed mechanisms in other muscle and inflammatory diseases, but applying these tools to ME/CFS is relatively new and exploratory.
