Advances in the role and mechanism of zonulin pathway in kidney diseases

摘要
The intestinal barrier is the first line of defense against foreign antigens. Tight junctions play an important role in maintaining the function of the intestinal wall. Zonulin is the only physiological protein discovered in recent years that can reversibly regulate tight junctions in human body. It changes the permeability of intestinal epithelial cells by regulating the state of tight junctions. Increased intestinal permeability can lead to abnormal activation of intestinal mucosal immune and bacterial translocation, then inducing systemic inflammation. It has already been reported that zonulin plays an important pathogenic role in a variety of diseases by regulating tight junctions leading to an abnormal increase of intestinal permeability. However, the research on the pathogenic role and mechanism of zonulin pathway in kidney disease is still in its infancy. Therefore, we reviewed the progress on pathophysiological characteristics of zonulin as well as the pathogenesis of zonulin in kidney disease in this paper.
