Role of Gastrointestinal Muscularis Macrophages in Regulation of Gastrointestinal Motility / 胃肠病学

Recent studies have found a special class of macrophages, muscularis macrophages (MMs), in the gastrointestinal tract, which interacts with enteric neuron (EN), interstitial cells of Cajal (ICC), and smooth muscle cells (SMC) to maintain normal intestinal motility. MMs can undergo phenotypic and other changes under altered intestinal microbiota, inflammation, or stress, and act on EN, ICC, or SMC through multiple mechanisms, ultimately affecting gastrointestinal motility. This article reviewed the mechanism of gastrointestinal MMs regulating gastrointestinal motility and role in gastrointestinal motility disorder diseases.
