Facilitation of glutamate receptors enhances memory.
A benzamide drug that crosses the blood-brain barrier and facilitates DL-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor-mediated synaptic responses was tested for its effects on memory in three behavioral tasks. The compound reversibly increased the amplitude and prolonged the duration of field excitatory postsynaptic potentials in hippocampal slices and produced compa...
متن کاملBlock of 5-HT2 Receptors Enhances Hippocampal Long-Term Potentiation
The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI...
متن کاملLuminal L-glutamate enhances duodenal mucosal defense mechanisms via multiple glutamate receptors in rats.
Presence of taste receptor families in the gastrointestinal mucosa suggests a physiological basis for local and early detection of a meal. We hypothesized that luminal L-glutamate, which is the primary nutrient conferring fundamental umami or proteinaceous taste, influences mucosal defense mechanisms in rat duodenum. We perfused the duodenal mucosa of anesthetized rats with L-glutamate (0.1-10 ...
متن کاملcAMP-dependent facilitation of glutamate release by beta-adrenergic receptors in cerebrocortical nerve terminals.
We have investigated the presence of a cAMP-protein kinase A-dependent pathway in cerebrocortical nerve terminals and its role in the modulation of glutamate release. The activation of adenylyl cyclase with forskolin enhances intrasynaptosomal cAMP and induces Ca2+-dependent glutamate release. The membrane permeant analogue dibutyryl cAMP mimics this facilitatory effect, whereas the inactive co...
متن کاملIonotropic Glutamate Receptors and their Role in Neurological Diseases
Glutamate is extensively and relatively uniformly distributed in the central nervous system (CNS) and its effects mediated by two distinct groups of receptors including Ionotropic and metabotropic glutamate receptors. Concentration of glutamate in the nervous system is much higher than in other tissues. Glutamate receptors play an important role in synaptic transmission, neural plasticity and n...
