It has been repeatedly reported that spinal motor neurons are selectively vulnerable to AMPA receptor‐mediated excitotoxicity. Therefore, identifying the uniqueness of AMPA receptors that are expressed on motor neurons, especially in individuals affected with sporadic amyotrophic lateral sclerosis (ALS) is essential for elucidating the etiology of this disorder. The mechanism that initiates motor neuronal death appears to be an exaggerated influx of Ca2+ through AMPA receptors. The determinants… 
Calcium Permeable-AMPA Receptors and Excitotoxicity in Neurological Disorders
TLDR
Considering the low expression or absence of CP-AMPARs in most cells, specific manipulation of the CP-ampARs might be a more plausible strategy to delay the onset and progression of pathological alterations with fewer side effects than blocking NMDARs.
Sub-cellular localization and regulatory mechanisms of AMPA receptors in motor neurons of a murine model of familial Amyotrophic Lateral Sclerosis
TLDR
Increased level of the trafficking protein NSF, able to increase the delivery of GluR2 at the cell surface, was reported selectively in the motor neurons at the presymptomatic stage of the disease in SOD1G93A mice, suggesting that the increase of NSF may be an attempt to protect motor neurons from excitotoxicity by maintaining the sufficient levels of GLUR2 subunit in the membrane.
Induced Loss of ADAR2 Engenders Slow Death of Motor Neurons from Q/R Site-Unedited GluR2
TLDR
GluR2 Q/R site editing causes AMPA receptor-mediated death of motor neurons in genetically modified mice and shows a decline in motor function commensurate with the slow death of ADAR2-deficient motor neurons.
Testing of the therapeutic efficacy and safety of AMPA receptor RNA aptamers in an ALS mouse model
TLDR
A 12-wk continuous, intracerebroventricular infusion of aptamers to AR2 mice reduced the progression of motor dysfunction, normalized TDP-43 mislocalization, and prevented death of motor neurons.
The AMPA receptor antagonist perampanel robustly rescues amyotrophic lateral sclerosis (ALS) pathology in sporadic ALS model mice
TLDR
It is shown that orally administered perampanel, a selective, non-competitive AMPA receptor antagonist significantly prevented the progression of the ALS phenotype and normalized the TDP-43 pathology-associated death of motor neurons in the AR2 mice.
AMPA receptor‐mediated neuronal death in sporadic ALS
TLDR
It is likely that an increase of the proportion of Q/R site‐unedited GluR2‐containing Ca2+‐permeable AMPA receptors initiates the death of motor neurons in sporadic ALS.

GluR2-dependent properties of AMPA receptors determine the selective vulnerability of motor neurons to excitotoxicity.
TLDR
Electrophysiological properties of AMPA receptors, known to be dependent on the relative abundance of GluR2: sensitivity to external polyamines, rectification index, and relative Ca(2+) permeability), correlated well with each other and with the selective vulnerability of motor neurons because motor neurons surviving an excitotoxic event had similar characteristics as dorsal horn neurons.
Human spinal motoneurons express low relative abundance of GluR2 mRNA: an implication for excitotoxicity in ALS
TLDR
The first quantitative measurements of the expression profile of AMPA receptor subunits mRNAs in human single neurons are provided by means of quantitative RT–PCR with a laser microdissector, showing that among the AMPA subunits, GluR2 shared the vast majority throughout the neuronal subsets and tissues examined.
Deficient RNA editing of GluR2 and neuronal death in amyotropic lateral sclerosis
TLDR
GluR2 underediting occurs in a disease specific and region selective manner and is likely that the molecular mechanism underlying the deficiency in RNA editing is a reduction in the activity of ADAR2, a double- strand RNA specific deaminase.
The Influence of Glutamate Receptor 2 Expression on Excitotoxicity in GluR2 Null Mutant Mice
AMPA receptor (AMPAR)-mediated ionic currents that govern gene expression, synaptic strength, and plasticity also can trigger excitotoxicity. However, native AMPARs exhibit heterogeneous
AMPA Receptor Calcium Permeability, GluR2 Expression, and Selective Motoneuron Vulnerability
TLDR
The results indicate that the selective vulnerability of motoneurons to AMPA receptor agonists is not determined solely by whole-cell relative Ca2+ permeability of AMPA receptors.
AMPA Exposures Induce Mitochondrial Ca2+ Overload and ROS Generation in Spinal Motor Neurons In Vitro
TLDR
Adding either antioxidants or toxins (FCCP or CN−) that block mitochondrial Ca2+ uptake attenuated AMPA/kainate receptor-mediated motor neuron injury, suggesting that the mitochondrial Ca 2+ uptake and consequent ROS generation are central to the injury process.
GluR2 AMPA Receptor Subunit Expression in Motoneurons at Low and High Risk for Degeneration in Amyotrophic Lateral Sclerosis
TLDR
Exchange of GluR2 mRNA and protein in motoneurons that differ in their vulnerability to degeneration in ALS suggests that reduced expression of GLUR2 is not a factor predisposing mot oneurons to degenerations.
Protective Effect of Parvalbumin on Excitotoxic Motor Neuron Death
TLDR
It is concluded that the high density of Ca(2+)-permeable AMPA receptors on the motor neuron's surface results in high Ca( 2+) transients upon stimulation and that the low cytosolic Ca(1+)-buffering capacity of motor neurons may contribute to the selective vulnerability of these cells in ALS.
Characterization of the AMPA‐Activated Receptors Present on Motoneurons
TLDR
The data show that despite high levels of edited GluR2 mRNA, some AMPARs are Ca2+‐permeable, and this subset of AM PARs can account for the AMPAR‐mediated Ca2- inflow inferred from cobalt uptake and electrophysiology studies.
