Organization of NMDA receptors at extrasynaptic locations [PDF]
Neuroscience, 2010 NMDA receptors are found in neurons both at synapses and in extrasynaptic locations. Extrasynaptic locations are poorly characterized. Here we used preembedding immunoperoxidase and postembedding immunogold electron microscopy and fluorescence light microscopy to characterize extrasynaptic NMDA receptor locations in dissociated hippocampal neurons in ...

Frontiers in Cellular Neuroscience, 2015 Despite numerous advances, treatment-resistant seizures remain an important problem. Loss of neuronal inhibition is present in a variety of epilepsy models and is suggested as a mechanism for increased excitability, leading to the proposal that grafting ...

Extrasynaptic neuron-glia communication [PDF]
Communicative & Integrative Biology, 2011 Chemical synaptic transmission between neurons is believed to take place at specialized sites of cell contact, comprising presynaptic terminals and postsynaptic membranes. Neurotransmitter release has been shown to occur also extrasynaptically, mainly targeting glial cells. In a recent study, we investigated the mechanism of extrasynaptic glutamate and

Frontiers in Physiology, 2012 We review the evidence of exocytosis from extrasynaptic sites in the soma, dendrites and axonal varicosities of central and peripheral neurons of vertebrates and invertebrates, and how it may contribute to signaling in the nervous system.

Astrocytic Actions on Extrasynaptic Neuronal Currents [PDF]
Frontiers in Cellular Neuroscience, 2015 In the last few decades, knowledge about astrocytic functions has significantly increased. It was demonstrated that astrocytes are not passive elements of the central nervous system (CNS), but active partners of neurons. There is a growing body of knowledge about the calcium excitability of astrocytes, the actions of different gliotransmitters and ...

Organization, control and function of extrasynaptic NMDA receptors [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 N -methyl d -aspartate receptors (NMDARs) exist in different forms owing to multiple combinations of subunits that can assemble into a functional receptor. In addition, they are located not only at synapses but also at extrasynaptic sites.

Frontiers in Synaptic Neuroscience, 2018 This review article deals with the mechanisms of extrasynaptic release of transmitter substances, namely the release from the soma, axon and dendrites in the absence of postsynaptic counterparts.

Frontiers in Neuroscience, 2020 The consequence of repeated cocaine exposure and prolonged abstinence on glutamate receptor expression in the nucleus accumbens has been extensively studied. However, the early effects of cocaine on NMDAR signaling remain unknown. NMDAR signaling depends

Oligomerization and cell surface expression of recombinant GABAA receptors tagged in the δ subunit
Journal of Integrative Neuroscience, 2019 The γ-Aminobutyric acid type A receptors (GABAARs) are heteropentameric chloride channels responsible for primary inhibition in the mammalian brain.

Frontiers in Pharmacology, 2019 Seizures induced by organophosphorus nerve agent exposure become refractory to treatment with benzodiazepines because these drugs engage synaptic γ-aminobutyric acid-A receptors (GABAARs) that rapidly internalize during status epilepticus (SE ...
