Tau is required for the function of extrasynaptic NMDA receptors
Scientific Reports, 2019 Tau is a microtubule-associated neuronal protein found mainly in axons. However, increasing evidence indicates that it is also present in dendrites, where it serves as an essential mediator of synaptic NMDA (N-methyl-D-aspartate) receptor-dependent ...

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 ...

Extrasynaptic vesicle recycling in mature hippocampal neurons [PDF]
Nature Communications, 2011 Fast neuronal signalling relies on highly regulated vesicle fusion and recycling at specialized presynaptic terminals. Recently, examples of non-classical neurotransmission have also been reported, where fusion of vesicles can occur at sites remote from conventional synapses.

Tonic neuromodulation of the inspiratory rhythm generator
Frontiers in Physiology, 2012 The generation of neural network dynamics relies on the interactions between the intrinsic and synaptic properties of their neural components. Moreover, neuromodulators allow networks to change these properties and adjust their activity to specific ...

Reduced neurosteroid potentiation of GABAA receptors in epilepsy and depolarized hippocampal neurons [PDF]
, 2020 OBJECTIVE: Neurosteroids regulate neuronal excitability by potentiating γ-aminobutyric acid type-A receptors (GABARs). In animal models of temporal lobe epilepsy, the neurosteroid sensitivity of GABARs is diminished and GABAR subunit composition is ...

C-Terminal truncation of NR2A subunits impairs synaptic but not extrasynaptic localization of NMDA receptors [PDF]
, 2000 NMDA receptors interact via the extended intracellular C-terminal domain of the NR2 subunits with constituents of the postsynaptic density for purposes of retention, clustering, and functional regulation at central excitatory synapses.

GABABReceptors Regulate Extrasynaptic GABAAReceptors [PDF]
The Journal of Neuroscience, 2013 Tonic inhibitory GABAAreceptor-mediated currents are observed in numerous cell types in the CNS, including thalamocortical neurons of the ventrobasal thalamus, dentate gyrus granule cells, and cerebellar granule cells. Here we show that in rat brain slices, activation of postsynaptic GABABreceptors enhances the magnitude of the tonic GABAAcurrent ...

AMPA Receptor Phosphorylation and Synaptic Colocalization on Motor Neurons Drive Maladaptive Plasticity below Complete Spinal Cord Injury. [PDF]
, 2015 Clinical spinal cord injury (SCI) is accompanied by comorbid peripheral injury in 47% of patients. Human and animal modeling data have shown that painful peripheral injuries undermine long-term recovery of locomotion through unknown mechanisms ...
