Crosstalk between Muscularis Macrophages and Enteric Neurons Regulates Gastrointestinal Motility
Intestinal peristalsis is a dynamic physiologic process influenced by dietary and microbial changes. It is tightly regulated by complex cellular interactions; however, our understanding of these controls is incomplete. A distinct population of macrophages is distributed in the intestinal muscularis externa. We demonstrate that, in the steady state, muscularis macrophages regulate peristaltic ac...
متن کاملInterleukin-6 expression and regulation in rat enteric glial cells.
As yet, little is known about the function of the glia of the enteric nervous system (ENS), particularly in an immune-stimulated environment. This prompted us to study the potential of cultured enteroglial cells for cytokine synthesis and secretion. Jejunal myenteric plexus preparations from adult rats were enzymatically dissociated, and enteroglial cells were purified by complement-mediated cy...
متن کاملEnteric Glial Cells: A New Frontier in Neurogastroenterology and Clinical Target for Inflammatory Bowel Diseases
The word "glia" is derived from the Greek word "γλoια," glue of the enteric nervous system, and for many years, enteric glial cells (EGCs) were believed to provide mainly structural support. However, EGCs as astrocytes in the central nervous system may serve a much more vital and active role in the enteric nervous system, and in homeostatic regulation of gastrointestinal functions. The emphasis...
متن کاملEssential roles of enteric neuronal serotonin in gastrointestinal motility and the development/survival of enteric dopaminergic neurons.
The gut contains a large 5-HT pool in enterochromaffin (EC) cells and a smaller 5-HT pool in the enteric nervous system (ENS). During development, enteric neurons are generated asynchronously. We tested hypotheses that serotonergic neurons, which arise early, affect development/survival of later-born dopaminergic, GABAergic, nitrergic, and calcitonin gene-related peptide-expressing neurons and ...
متن کاملGastrointestinal Motility
Anatomic regions of the stomach are the fundus, corpus (body), antrum and pylorus. The functional regions of the stomach do not correspond to the anatomic regions. Functionally, the stomach can be divided into the gastric reservoir and the gastric pump (Fig. 1). The gastric reservoir consists of the fundus and corpus. The gastric pump is represented by the area at which peristaltic waves occur:...
