Local Pentraxin-2 Deficit Is a Feature of Intestinal Fibrosis in Crohn's Disease.

This exploratory study is the first analysis of PTX-2 within the intestine, and demonstrates that PTX-2 signal is reduced in the architecturally normal bowel of patients with FCD. Lower submucosal PTX-2 levels in patients with re-stenosis raises the possibility of a protective role of PTX-2 in intestinal fibrosis.
