Role of Dietary Free Glutamate in Gastrointestinal Function
Glutamate is a non-essential amino acid that confers umami taste. Recently, several taste receptors for umami taste have been identified in the oral cavity as well as in the gastrointestinal tract. Gustatory stimulation of the tongue by glutamate activates vagal gastric, pancreatic, and hepatic efferent nerves. In the gastrointestinal tract, glutamate excites afferent fibers of the abdominal va...
متن کاملPhysiological role of dietary free glutamate in the food digestion.
Gustatory and anticipatory cephalic stimuli during a meal yield nutritional information and aid efficient food digestion. Mammals, including humans, can detect the amount of dietary protein and its quality via cephalic relay to initiate proper digestion in the upper gastrointestinal (GI) tract. In addition to gustatory stimuli, visceral sensing by the abdominal vagus conveys primary afferent nu...
متن کاملNutritional and physiological significance of luminal glutamate-sensing in the gastrointestinal functions.
Recent evidence indicates that free amino acids are nutrients as well as acting as chemical transmitters within the gastrointestinal tract. Gut glutamate research is the most advanced among 20 amino acids. Free glutamate carries the umami taste sensation on the tongue and a visceral sensation in the gut, especially the stomach. In the field of taste physiology, the physiological meaning of the ...
متن کاملPhysiological roles of glutamate signaling in gut and brain function.
Some ingested nutrients have postingestive effects that modulate food intake and improve mood subconsciously. Here, we provide an overview of the positive postingestive effects of such nutrients, primarily L-glutamate, sugar, and lipids, with respect to behavior and brain function. We also discuss the mechanisms of brain activation resulting from signaling through the gut-brain axis. Recent stu...
متن کاملMICROGLIAL GLUTAMATE TRANSPORTERS Regulation of Expression and Possible Physiological Functions
Microglia are considered as the immunocompetent cells of the central nervous system (CNS). Being the first line of defence, they have prominent roles in monitoring the homeostasis and the extracellular milieu and can rapidly and specifically react to any disturbances such as brain trauma, ischemia, neurodegenerative diseases, or infections. Microglia are normally adapted to a resting state, but...
