Mapping nerve cells around the jaw joint in people with and without TMJ pain
Comprehensive functional phenotyping of trigeminal neurons innervating temporomandibular joint (TMJ) tissues in male female and aged mice primates and humans with and without TMJ disorders (TMJD)
Researchers are mapping the types and changes of nerves around the jaw joint to help understand TMJ pain in people and animal models.

What this research studies
The team will examine nerve cells that connect to the temporomandibular joint using tissue samples and advanced imaging and molecular tests from mice, primates, and human donors. They will compare samples from men, women, and older adults, and from people with and without TMJ disorder to see how nerve types and wiring differ with pain. The goal is to produce a detailed map of nerve locations and characteristics in muscles, cartilage, capsule, and ligaments around the TMJ. This work may also highlight specific nerve-related targets that could guide new treatments.
Who could benefit from this research
Good fit: Adults with TMJ disorder or chronic jaw pain, and people willing to donate TMJ tissue or take part in related clinical visits, would be ideal candidates to contribute.
Not a fit: People with pain unrelated to the TMJ or those unwilling to provide tissue samples or attend study visits are unlikely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could point to new nerve-based targets that lead to better treatments for TMJ pain.
How similar studies have performed: Prior studies have identified distinct trigeminal nerve types in TMJ tissue, but a comprehensive, cross-species functional map and target search is largely novel.
