Unique cells in jaw joint fluid linked to TMJ pain

Single cell analysis of healthy and diseased temporomandibular joint synovial fluid

NIH-funded research Thomas Jefferson University · NIH-11172234

This project uses single-cell gene testing of jaw joint fluid and blood to find cell types tied to pain in people with temporomandibular joint disorders (TMJDs).

What this research studies

You would be asked to provide a small sample of synovial fluid from the temporomandibular (jaw) joint and a blood sample at Thomas Jefferson University. Researchers will develop safe collection procedures, then use single-cell RNA sequencing to read gene activity in each cell from both people with TMJ pain and people without symptoms. By comparing cells from painful and healthy joints, the team hopes to identify a unique cell population or gene signals that track with pain. Any findings could point to new diagnostic markers or treatment targets for people with TMJ disorders.

Who could benefit from this research

Good fit: Ideal candidates are people of any age with symptomatic TMJ disorders who can provide joint fluid and blood samples, as well as healthy volunteers without TMJ pain to serve as controls.

Not a fit: People without TMJ symptoms, those who cannot undergo joint fluid collection, or anyone seeking immediate pain relief are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could point to new tests or treatments that better target the source of TMJ pain.

How similar studies have performed: Single-cell RNA sequencing has revealed disease-driving cell types in other joint conditions, but applying this method to TMJ synovial fluid is a novel approach.
