Core Tip

Core Tip: This study shows that intramuscular interstitial cells of Cajal (ICC-IM) play crucial roles in regulating the activity of gastric antral migrating motor complexes (MMC). This may be an important bridge between the vagus, enteric nervous system and motilin to regulate smooth muscle contraction. Through the muscarinic receptor pathway on ICC-IM, the Chinese medicine Xiangbinfang granules depolarize smooth muscle cells and initiates an action potential, changing the periodic motion of MMC into a phase III-like contraction pattern in the gastric antrum of mice.
