In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

Cytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Preferential assembly of heteromeric kainate and AMPA receptor amino terminal domains

eLife, 2017
Ion conductivity and the gating characteristics of tetrameric glutamate receptor ion channels are determined by their subunit composition. Competitive homo- and hetero-dimerization of their amino-terminal domains (ATDs) is a key step controlling assembly.

State based model of long-term potentiation and synaptic tagging and capture [PDF]

, 2009
Recent data indicate that plasticity protocols have not only synapse-specific but also more widespread effects. In particular, in synaptic tagging and capture (STC), tagged synapses can capture plasticity-related proteins, synthesized in response to ...

Evidence for multiple AMPA receptor complexes in hippocampal CA1/CA2 neurons

Journal of Neuroscience, 1996
The AMPA receptor, which is involved in most fast glutamatergic transmission in the mammalian brain and is expressed in most neurons, is made up of four subunits, GluR1–4.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Differential Regulation of AMPA Receptor and GABA Receptor Trafficking by Tumor Necrosis Factor-α

Journal of Neuroscience, 2005
The proinflammatory cytokine tumor necrosis factor-α (TNFα) causes a rapid exocytosis of AMPA receptors in hippocampal pyramidal cells and is constitutively required for the maintenance of normal surface expression of AMPA receptors.

AMPA receptor biogenesis and trafficking

Current Opinion in Neurobiology, 2007
AMPA-type glutamate receptors mediate the majority of fast excitatory transmission in the central nervous system. The trafficking of AMPA receptors to and from synapses alters synaptic strength and has been recognized as a central mechanism underlying various forms of synaptic plasticity.

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

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
