Association between cytokine imbalance and intestinal barrier injury in irritable bowel syndrome

As a common and frequently-occurring disease, irritable bowel syndrome (IBS) has been paid more and more attention. In recent years, with the development of cell biology and molecular biology, the research on IBS has been shifted from functional to organic direction. Studying the association between cytokine imbalance and intestinal barrier injury in IBS is aimed to assess a more meaningful treatment for IBS in the process of searching for effective drugs, so as to provide new avenues for better treatment of the disease.

New advances in non-invasive assessment of intestinal epithelial barrier function

Abnormal intestinal permeability has been suggested to play an important role in many human diseases, including diabetes, inflammatory bowel disease, celiac disease, multiple sclerosis, food allergy and hypersensitivity, and irritable bowel syndrome. Emerging work in recent years has begun to provide evidence for an etiologic role of abnormal intestinal permeability in the pathogenesis of autoimmune disease. Insight into gut barrier integrity and function loss is important to improve our knowledge on disease etiology and pathophysiology and contributes to early detection and/or secondary prevention of disease. A variety of tests have been developed to assess intestinal epithelial cell damage, intestinal tight junction status and consequences of intestinal barrier integrity loss, i.e. increased intestinal permeability. This review discusses currently available methods for evaluating human intestinal barrier function.
