T cells in ulcerative colitis

This study collects blood and tissue samples to better understand how the immune system behaves in people with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. It aims to advance research rather than test a specific new treatment, and it also enrolls healthy volunteers for comparison.

This trial looks at different ways to measure healing in the gut lining of people with ulcerative colitis, using samples from previous checkups. It aims to find the best way to tell if treatment is working.

This study checks biomarkers (signals in blood and/or stool) in adults with moderate-to-severe ulcerative colitis. It compares patients starting targeted medicines and looks for marker patterns that may reflect how the disease is behaving.

This study collects blood, tissue, and other samples from people with autoimmune diseases like Crohn's disease, multiple sclerosis, or lupus. Researchers will study your immune cells (T cells) to learn what they are attacking, which could lead to better treatments in the future.

This trial uses a gentle ultrasound scan (on the outside of the body) to see how well treatment is working during a moderate to severe flare of ulcerative colitis. It aims to find out if this painless test can predict recovery and help guide care without needing a telescope exam (endoscopy).

This study is looking at how the immune system works in people with inflammatory bowel disease (IBD), which includes conditions like Crohn's disease and ulcerative colitis. By comparing blood or tissue samples from people with and without IBD, researchers hope to find better ways to treat the disease in the future.
