NLRP6 Inflammasome Orchestrates the Colonic Host-Microbial Interface by Regulating Goblet Cell Mucus Secretion
Mucus production by goblet cells of the large intestine serves as a crucial antimicrobial protective mechanism at the interface between the eukaryotic and prokaryotic cells of the mammalian intestinal ecosystem. However, the regulatory pathways involved in goblet cell-induced mucus secretion remain largely unknown. Here, we demonstrate that the NLRP6 inflammasome, a recently described regulator...
متن کاملMucus Properties and Goblet Cell Quantification in Mouse, Rat and Human Ileal Peyer's Patches
Peyer's patches (PPs) are collections of lymphoid follicles in the small intestine, responsible for scanning the intestinal content for foreign antigens such as soluble molecules, particulate matter as well as intact bacteria and viruses. The immune cells of the patch are separated from the intestinal lumen by a single layer of epithelial cells, the follicle-associated epithelium (FAE). This ep...
متن کاملAirway mucus obstruction: mucin glycoproteins, MUC gene regulation and goblet cell hyperplasia.
The mucus layer that coats the airway epithelium provides a protective barrier against pathogenic and noxious agents and participates in the mucosal response to inflammation and infection. Airway mucus is composed of water, ions, lung secretions, serum protein transudates, and mucin glycoproteins (mucins). Mucins are the major components of mucus and the macromolecules that impart rheologic pro...
متن کاملAltered Goblet Cell Differentiation and Surface Mucus Properties in Hirschsprung Disease
Hirschsprung disease-associated enterocolitis (HAEC) leads to significant mortality and morbidity, but its pathogenesis remains unknown. Changes in the colonic epithelium related to goblet cells and the luminal mucus layer have been postulated to play a key role. Here we show that the colonic epithelium of both aganglionic and ganglionic segments are altered in patients and in mice with Hirschs...
متن کاملMembrane changes associated with mucus production by intestinal goblet cells.
Changes in the structural organization of membranes of mucous bodies and the plasma membrane that occur during mucus production in goblet cells of rat rectum have been studied by thin-section and freeze-fracture techniques. Immature mucous bodies are bounded by a trilaminar membrane and fracture faces of the membrane have randomly distributed intramembrane particles. During maturation, mucous b...
