Identification of Synovial Lymphatics in the TMJ and their Roles in Arthritis and PainResearch square · 2025
Summary (written by the submitters)
Temporomandibular joint (TMJ) arthritis is a craniofacial disorder characterized by joint dysfunction and orofacial pain. Despite of its established roles in fluid and immune regulation, lymphatic regulation, and function in TMJ remain unknown. Using genetic report mouse, uDISCO tissue clearing, and 3D volume imaging, we defined lymphatic vessel morphology, structure, anatomic location in adult mouse TMJ.

We demonstrate in a mouse model of TMJ osteoarthritis (TMJOA) that arthritis induces inflammatory lymphangiogenesis and leads to impaired synovial lymphatic functions, including decreases in synovial influx and lymph node fluid drainage. To establish the causative link between lymphatic remodeling and TMJOA, we performed lymphatic loss- and gain-of-function studies. Lymphatic deficiency exacerbated cartilage defects, bone loss, synovitis, synovial fibrosis, and pain behaviors in TMJOA mice. Conversely, lymphatic activation via a hydrogel-mediated VEGF-C delivery to TMJ reduced TMJ pain, inflammation, and arthritis-like pathogenesis. Therefore, we defined lymphatic structure in TMJ and found that lymphatic dysfunction drives TMJOA pathogenesis and pain, suggesting its potential as a therapeutic target.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE295404_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1254606 and SRA study SRP580842. Searching any of these in the dataset finder brings you back here.
