It may contain information that applies to only to some subtypes and species, and so should not be considered definitional. Enteroendocrine cells are a specialized subset of cells located within the epithelial lining of both the small and large intestines, as well as the stomach and pancreas. Constituting less than 1% of the total population of intestinal cells, they are differentiated from a common intestinal cell progenitor, thus sharing lineage with absorptive and goblet cells of the intestines. The distinct characteristic feature of an enteroendocrine cell is its inherent capacity to synthesize and secrete a plethora of gut hormones such as serotonin, somatostatin, neurotensin, cholecystokinin, secretin, gastric inhibitory peptide, motilin, and glucagon-like peptide-1. Integrated within this complex network of signaling agents, these substances control various aspects of the digestive system. Each enteroendocrine cell has its unique combination of hormones to release, determined by its position along the intestinal tract. Intriguingly, these hormones not only modulate local gut function, including motility, absorption and secretion, but also potentiate distant actions on other systems such as endocrine, nervous and immune and play a role in the feeling of satiety. The release of these hormones from enteroendocrine cells is a highly regulated and dynamic process. The cells are equipped with sensory receptors localized on its luminal side that respond to various stimuli, including changes in nutrient composition, chemical or mechanical changes in the gut lumen, or even signals arising from commensal microbiota. This sensory input stimulates a signaling cascade within the cell, culminating in the release of specific hormones into the interstitial fluid. These hormones then make their way into the bloodstream, acting on their respective target receptors to mediate their duties. The multifunctional characteristics of enteroendocrine cells make them crucial for maintaining gut homeostasis and the overall physiological well being of the body. |
