Molecular constituents of neuronal AMPA receptors [PDF]

open access: yesThe Journal of Cell Biology, 2005
Dynamic regulation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) underlies aspects of synaptic plasticity. Although numerous AMPAR-interacting proteins have been identified, their quantitative and relative contributions to native AMPAR complexes remain unclear.

Role of Glutamate Excitotoxicity in Glioblastoma Growth and Its Implications in Treatment

open access: yesCell Biology International, EarlyView.
ABSTRACT Glioblastoma is a highly malignant and invasive type of primary brain tumor that originates from astrocytes. Glutamate, a neurotransmitter in the brain plays a crucial role in excitotoxic cell death. Excessive glutamate triggers a pathological process known as glutamate excitotoxicity, leading to neuronal damage.

Downregulation of GluA2 AMPA receptor subunits reduces the dendritic arborization of developing spinal motoneurons. [PDF]

open access: yesPLoS ONE, 2012
AMPA receptors lacking the GluA2 subunit allow a significant influx of Ca(2+) ions. Although Ca(2+)-permeable AMPA receptors are a familiar feature at early stages of development, the functional significance of these receptors during the maturation of ...

AMPA receptors as a molecular target in epilepsy therapy

open access: yesActa Neurologica Scandinavica, Supplementum, 2013
Epileptic seizures occur as a result of episodic abnormal synchronous discharges in cerebral neuronal networks. Although a variety of non‐conventional mechanisms may play a role in epileptic synchronization, cascading excitation within networks of ...

Potential wells for AMPA receptors organized in ring nanodomains [PDF]

open access: yesarXiv, 2013
By combining high-density super-resolution imaging with a novel stochastic analysis, we report here a peculiar nano-structure organization revealed by the density function of individual AMPA receptors moving on the surface of cultured hippocampal dendrites.

A Thermodynamic Model for Receptor Clustering [PDF]

open access: yes, 1999
Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.

Autoantibodies to Epilepsy-Related LGI1 in Limbic Encephalitis Neutralize LGI1-ADAM22 Interaction and Reduce Synaptic AMPA Receptors

open access: yesJournal of Neuroscience, 2013
More than 30 mutations in LGI1, a secreted neuronal protein, have been reported with autosomal dominant lateral temporal lobe epilepsy (ADLTE). Although LGI1 haploinsufficiency is thought to cause ADLTE, the underlying molecular mechanism that results in

Calcium-Permeable AMPA Receptors in the Nucleus Accumbens Regulate Depression-Like Behaviors in the Chronic Neuropathic Pain State

open access: yesJournal of Neuroscience, 2013
Depression is a salient emotional feature of chronic pain. Depression alters the pain threshold and impairs functional recovery. To date, however, there has been limited understanding of synaptic or circuit mechanisms that regulate depression in the pain

Self‐limited familial focal epilepsy caused by ANK2 variants: A potentially under‐recognized condition

open access: yesEpilepsia Open, EarlyView.
Abstract The Ankyrin 2 (ANK2) gene encodes the ankyrin‐B protein (ANKB), which is involved in the organization and stability of membrane ion channels, transporters, and receptors in cardiomyocytes and neurons. Variants in ANK2 genes are initially reported in long QT syndrome and autism.

Chronic renal failure induces cell death in rat hippocampal CA1 via upregulation of αCaMKII/NR2A synaptic complex and phosphorylated GluR1-containing AMPA receptor cascades

open access: yesKidney Research and Clinical Practice, 2014
Background: N-methyl-D-aspartate (NMDA) and alpha-amino-3-hydroxy-5-methylisoxazole-4-propinoic acid (AMPA) receptors bound to postsynaptic density-95 (PSD-95) and α isoform of calcium/calmodulin-dependent protein kinase II (αCaMKII) is fundamentally ...
