Exciting news for those with fistulising Crohn's disease - hopefully relief can be on the way soon
Scientists at Oxford University have identified the rogue fibroblast cells at the heart of Crohn’s disease fistulas, which are painful tunnel like tracts that affect up to 30 percent of patients.
Using cutting edge single cell and spatial analysis, the researchers found these fibroblasts behave like fetal gut cells, aggressively breaking down tissue and laying down scar tissue. This process allows these tunnels to form and persist.
Excitingly, traces of these cells are seen even in very early Crohn’s ulcers, meaning new treatments could one day prevent fistulas before they start.
The team’s work creates a valuable public resource for scientists and offers hope for novel drug discovery focused on real gut healing, not just inflammation control.
This could transform care for people with inflammatory bowel disease worldwide.
If you or someone you know is affected by Crohn’s, this breakthrough brings us closer to more effective treatments and better futures.
