CORNELL UNIVERSITY ITHACA, N.Y. — A multi-year study of the role of E. coligut bacteria in Crohn’s disease finds that intestinal inflammation liberates chemicals that nourish the bacteria’s growth and promotes their ability to cause inflammation. The results identify new avenues for treatments that selectively disrupt the compounds that feed E. coli. The study, “Mucosal Metabolites...
Crohn’s disease is a type of inflammatory bowel disease (IBD). Its incidence and the increased risk of other conditions or complications are different in males and females. Although symptoms and treatment may vary, these differ for each individual, rather than across age or gender. The Good Brigade/Getty Images Crohn’s disease is a chronic condition that causes...
by Stony Brook University IL-17A acts on unique cell types to regulate intestinal function. Under normal conditions, IL-17A acts on stem cells to promote their differentiation into secretory epithelial cells. This visual depicts that during colitis, IL-17A acts on secretory cells to mitigate the disease’s inflammatory effects. Credit: Pawan Kumar A paper published this week...

Researchers using mouse models found that stress hormones suppressed the innate immune system that normally protects the gut...

Crohn’s disease is a bowel condition that causes inflammation along the digestive tract. It can cause malnutrition, so doctors may prescribe vitamins and supplements to prevent or treat this issue. Crohn’s disease typically causes symptoms to occur in cycles. People with the condition might experience episodes of abdominal pain, diarrhea, and other symptoms that come and...
UNIVERSITY OF LIMERICK New research led by University of Limerick in Ireland has revealed a direct link between fatty tissue and Crohn’s disease. The study, carried out by researchers at UL along with a team from University Hospital Limerick, is suggesting for the first time that Crohn’s disease, which is an inflammatory bowel condition, may...
