Immune cells in the bowel of people who suffer with celiac disease are permanently replaced by a new subset of cells that promote inflammation, finds a new study.
In celiac diseased individuals, the immune cells present in the intestines are permanently replaced by a new subset of cells that promote inflammation, reveals new research. Foundation for the progression of the disease is laid by this permanent ‘immunological scarring,’ which has long-term implications for gut health in diseased patients.// The results also suggest that the same process could be contributing to other chronic intestinal disorders, such as ulcerative colitis.
Dr James McLaren, from Cardiff University’s School of Medicine, said: "In celiac disease, T cells found in the bowel react to gluten and cause inflammation, which damages the lining of the bowel.
"Under normal circumstances, T cells have a protective role in the bowel and form a stable population. However, in celiac disease, they contribute to the inflammatory process, causing short-term symptoms and increasing the risk of developing certain types of bowel cancer.
"Our new study suggests that even though short-term symptoms, such as diarrhea and abdominal pain, can be alleviated by removing gluten from the diet, long-term implications may remain, because ’tissue-healing’ T cells in the bowel are permanently replaced by ’pro-inflammatory’ T cells."
Celiac disease is common and affects one in 100 people. The international team hope the new findings will help inform the treatment of chronic intestinal disorders.
