Scientists dig into genes to unravel IBD mysteries
NCT ID NCT01171872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to better understand inflammatory bowel disease (IBD) by collecting tissue samples from 1,100 people undergoing endoscopy or bowel surgery. Researchers will analyze gene activity, proteins, and gut microbes to learn what causes the disease. The study includes both people with and without IBD, and does not test any new treatment.
