Differential modulation of NMDA and AMPA receptors by cellular prion protein and copper ions
N-Methyl-D-aspartate receptors (NMDARs) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) are two major types of ionotropic glutamate receptors involved in synaptic transmission.

GRASP-1 A Neuronal RasGEF Associated with the AMPA Receptor/GRIP Complex [PDF]
The PDZ domain–containing proteins, such as PSD-95 and GRIP, have been suggested to be involved in the targeting of glutamate receptors, a process that plays a critical role in the efficiency of synaptic transmission and plasticity.

Blockade of adenosine A2A receptors prevents protein phosphorylation in the striatum induced by cortical stimulation [PDF]
©2006 Society for NeurosciencePrevious studies have shown that cortical stimulation selectively activates extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation and immediate early gene expression in striatal GABAergic enkephalinergic neurons.

Objectives Rheumatoid arthritis (RA) associated anti‐citrullinated protein antibodies (ACPA) target various antigens by binding short citrulline‐amino acid motifs, resulting in heterogeneous ACPA‐profiles among patients. Here we analyzed ACPA‐patterns by recognized citrulline‐motifs in relation to the RA risk factors HLA‐DRB1 shared epitope (SE ...

AMPA, NMDA and GABAA receptor mediated network burst dynamics in cortical cultures in vitro [PDF]
In this work we study the excitatory AMPA, and NMDA, and inhibitory GABAA receptor mediated dynamical changes in neuronal networks of neonatal rat cortex in vitro. Extracellular network-wide activity was recorded with 59 planar electrodes simultaneously under different pharmacological conditions.

AMPA-Net: Optimization-Inspired Attention Neural Network for Deep Compressed Sensing [PDF]
Compressed sensing (CS) is a challenging problem in image processing due to reconstructing an almost complete image from a limited measurement. To achieve fast and accurate CS reconstruction, we synthesize the advantages of two well-known methods (neural network and optimization algorithm) to propose a novel optimization inspired neural network which ...

Molecular constituents of neuronal AMPA receptors [PDF]
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
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]
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 ...

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