Ca2+ Influx through AMPA or Kainate Receptors Alone Is Sufficient to Initiate Excitotoxicity in Cultured Oligodendrocytes

Neurobiology of Disease, 2002
Oligodendrocytes are vulnerable to excitotoxic insults mediated by AMPA receptors and by low and high affinity kainate receptors, a feature that is dependent on Ca2+ influx.

Presynaptic adenosine receptor-mediated regulation of diverse thalamocortical short-term plasticity in the mouse whisker pathway [PDF]

, 2016
Short-term synaptic plasticity (STP) sets the sensitivity of a synapse to incoming activity and determines the temporal patterns that it best transmits.

Ion‐dependent gating of kainate receptors

The Journal of Physiology, 2009
Ligand‐gated ion channels are an important class of signalling protein that depend on small chemical neurotransmitters such as acetylcholine,l‐glutamate, glycine and γ‐aminobutyrate for activation. Although numerous in number, neurotransmitter substances have always been thought to drive the receptor complex into the open state in much the same way and

Alterations in kainate receptor and TRPM1 localization in bipolar cells after retinal photoreceptor degeneration

Frontiers in Cellular Neuroscience, 2015
Photoreceptor degeneration differentially impacts glutamatergic signaling in downstream On and Off bipolar cells. In rodent models, photoreceptor degeneration leads to loss of glutamatergic signaling in On bipolar cells, whereas Off bipolar cells appear ...

GABA-enhanced collective behavior in neuronal axons underlies persistent gamma-frequency oscillations [PDF]

, 2003
Gamma (30–80 Hz) oscillations occur in mammalian electroencephalogram in a manner that indicates cognitive relevance. In vitro models of gamma oscillations demonstrate two forms of oscillation: one occurring transiently and driven by discrete afferent ...

Imaging epileptic foci in mouse models via a low-density lipoprotein receptor-related protein-1 targeting strategy

EBioMedicine, 2021
Background: In the setting of drug-resistant epilepsy (DRE), the success of surgery depends on the ability to accurately locate the epileptic foci to be resected or disconnected.

Neurotransmitter modulation of extracellular H+ fluxes from isolated retinal horizontal cells of the skate

, 2004
Self-referencing H+-selective microelectrodes were used to measure extracellular H+ fluxes from horizontal cells isolated from the skate retina. A standing H+ flux was detected from quiescent cells, indicating a higher concentration of free hydrogen ions

Differential localization of glutamate receptor subunits at the drosophila neuromuscular junction [PDF]

, 2004
The subunit composition of postsynaptic neurotransmitter receptors is a key determinant of synaptic physiology. Two glutamate receptor subunits, Drosophila glutamate receptor IIA (DGluRIIA) and DGluRIIB, are expressed at the Drosophila neuromuscular ...

Kainate receptor physiology

Current Opinion in Pharmacology, 2006
Glutamate receptors constitute a complex signalling system at most of the excitatory synapses in the brain. Of the known ionotropic glutamate receptors, kainate receptors are ubiquitous in the central nervous system, and a considerable amount of data indicates that this class of receptors is present at both sides of the synapse.

Oligodendrocyte precursor cell AMPA receptors differ with age and brain region while kainate receptors remain stable

iScience
Summary: Oligodendrocyte precursor cells (OPCs) proliferate and differentiate into myelinating oligodendrocytes throughout life. Many cues modulate OPC proliferation and differentiation, including neuronal activity, which OPCs sense through voltage-gated
