NH125 reduces the level of CPEB3, an RNA binding protein, to promote synaptic GluA2 expression [PDF]

open access: yesNeuropharmacology, 2016
Neuronal activity can alter the phosphorylation state of eukaryotic elongation factor 2 (eEF2) and thereby regulates protein synthesis. This is thought to be the underlying mechanism for a form of synaptic plasticity that involves changes in the ...

PICK1 facilitates lasting reduction in GluA2 concentration in the hippocampus during chronic epilepsy

Epilepsy Research, 2017
Overstimulation of glutamate receptors resulting in excessive intracellular calcium concentrations is a major cause of neuronal cell death in epilepsy. The main source of increased calcium concentration during this excitotoxicity is an influx through NMDA subtype of glutamate receptors.

ADAR2-mediated Q/R editing of GluA2 in homeostatic synaptic plasticity

Science Signaling
Homeostatic synaptic plasticity is a negative feedback mechanism through which neurons modify their synaptic strength to counteract chronic increases or decreases in activity. In response to activity deprivation, synaptic strength is enhanced by increasing the number of AMPA receptors (AMPARs), particularly Ca 2 ...

Investigating the Effects of Perampanel on Autophagy-mediated Regulation of GluA2 and PSD95 in Epilepsy

Molecular Neurobiology
Epilepsy is a chronic neurological disorder characterized by recurrent seizures. Despite various treatment approaches, a significant number of patients continue to experience uncontrolled seizures, leading to refractory epilepsy. The emergence of novel anti-epileptic drugs, such as perampanel (PER), has provided promising options for effective epilepsy

GluA2-containing AMPA receptors form a continuum of Ca2+-permeable channels

Nature
Fast excitatory neurotransmission in the mammalian brain is mediated by cation-selective AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors (AMPARs)1. AMPARs are critical for the learning and memory mechanisms of Hebbian plasticity2 and glutamatergic synapse homeostasis3, with recent work establishing that AMPAR missense mutations ...

Stapled Peptides with Therapeutic Potential for Ischemic Stroke by Blocking the Endocytosis of GluA2 AMPAR

Journal of Medicinal Chemistry
Targeting the interaction between the C-terminal domain of the GluA2 subunit of AMPA receptors and BRAG2 presents a highly promising therapeutic approach for acute ischemic stroke. The membrane-permeable peptide Tat-GluA2-3Y has shown potential by competitively binding to BRAG2 to inhibit GluA2 endocytosis; however, its clinical application is limited ...
