Abstract:

Colitis is a common inflammatory bowel disease whose pathogenesis is related to immune regulation and intestinal microbial homeostasis. Exosomes are membrane vesicles secreted by cells that contain proteins, lipids, and other substances. Stem cells and macrophages can participate in the regulation of related diseases by secreting exosomes. It has been found that exosomes of stem cell and macrophage origin are closely involved in the regulation of colitis, and exosomes derived from stem cells, especially mesenchymal stem cells, play an important role in anti-colitis. This article reviews the role and possible mechanisms of mesenchymal stem cell-based and macrophage-derived exosomes in the regulation of colitis, aiming to provide ideas for in-depth study of colitis and new strategies for its treatment.

Key words: exosome, colitis, mesenchymal stem cell, macrophage
