Ulcerative colitis is a condition involving chronic inflammation of the lining of the large intestine. It leads to the formation of small sores called ulcers that cause digestive symptoms and sometimes complications such as malnutrition. Recent studies have helped scientists develop a better understanding of ulcerative colitis, including its potential causes and treatments. Ongoing research...

Unsaturated fats can help control damaging bouts of inflammation in colitis
by Bill Hathaway, Yale University Credit: Pixabay/CC0 Public DomainAn overly robust immune response to usually harmless germs has been linked to colitis, a potentially severe inflammation of the colon that afflicts millions of people worldwide. A new Yale-led study not only reveals that the presence of one class of fatty acids is the hidden villain that...

Bioengineered approach shows promise in ulcerative colitis
by UT Southwestern Medical Center Bioengineering and characterization of the immunosuppressive combinational colon-specific immune niche. Credit: Nature Biomedical Engineering (2023). DOI: 10.1038/s41551-023-01136-9By taking advantage of mechanisms that allow cancer cells to evade immune attack, UT Southwestern Medical Center researchers have developed a new strategy in animal models that has potential for treating ulcerative colitis. Their findings, reported...

Researchers identify why cancer immunotherapy can cause colitis
Studies in mice reveal the mechanism that induces this severe side effect and point to a solution that kills the cancer without causing gastrointestinal issues AuthorNicole Fawcett Jacob Dwyer, Michigan MedicineResearchers at the University of Michigan Health Rogel Cancer Center have identified a mechanism that causes severe gastrointestinal problems with immune-based cancer treatment. They also...

Researchers disrupt signaling pathway to treat colitis
The white blood cell TH17 helps the immune system fight infection by promoting inflammation. But it can be too much of a good thing: Excessive inflammation from TH17 overload has been tied to autoimmune disorders, such as inflammatory bowel disease (IBD) and arthritis. Researchers led by Hening Lin, professor of chemistry and chemical biology in the College...

Potential new therapy for Crohn’s, colitis identified
The cells that line the gut of an ulcerative colitis patient are inflamed and filled with a protein called PAI-1 (shown in red) that is linked to blood clotting. Nuclei are shown in blue, and other intestinal cells are marked in green. Researchers at Washington University School of Medicine in St. Louis have found that blocking the...

Scientists connect dots between colitis and colon cancer
AUGUSTA, Ga. (Jan. 14, 2019) – Lingering inflammation in the colon is a known risk factor for colorectal cancer and now scientists report one way it resets the stage to enable this common and often deadly cancer. Inflammation is supposed to be a short-term response to an infection or other irritant in the body that is essential to eliminating it. But when...
