Research Status of Exosomes and Pathogenesis of Inflammatory Bowel Disease / 胃肠病学

ABSTRACT

Exosomes are extracellular vesicles with a diameter of 30-150 nm, which exist in multi-vesicular bodies in the form of intraluminal vesicles. Exosomes can be secreted by a variety of immune cells. Studies have shown that exosomes might play an important role in IBD through their components, such as annexin-A1 (ANXA1), the miRNAs and lipids. As a carrier of antigen presentation, it can affect the signaling pathways related to IBD, regulate the immune response and intestinal homeostasis. This article reviewed the relationship between exosomes and IBD.
