Allosteric competition and inhibition in AMPA receptors. [PDF]

Nat Struct Mol Biol, 2023
Abstract Excitatory neurotransmission is principally mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-subtype ionotropic glutamate receptors (AMPARs). Negative allosteric modulators are therapeutic candidates that inhibit AMPAR activation and can compete with positive modulators to control AMPAR function through

Regulating AMPA Receptors with Isoxazole-4-Carboxamide Derivatives: An Electrophysiological Study [PDF]

Journal of Xenobiotics
Isoxazole carboxamide derivatives are intriguing modulators of ionotropic glutamate receptors; more specifically, their prospective analgesic activities based on non-opioid pathways have sparked widespread research.

GluA2-lacking AMPA receptors in hippocampal CA1 cell synapses: evidence from gene-targeted mice

Frontiers in Molecular Neuroscience, 2012
The GluA2 subunit in heteromeric AMPA receptor channels restricts Ca2+ permeability and block by polyamines, rendering linear the current-voltage relationship of these glutamate-gated cation channels.

α-Lipoic Acid Derivatives as Allosteric Modulators for Targeting AMPA-Type Glutamate Receptors’ Gating Modules

Cells, 2022
The ionotropic glutamate receptor subtype α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) is responsible for most excitatory transmission in the brain.

SynDIG1 promotes excitatory synaptogenesis independent of AMPA receptor trafficking and biophysical regulation. [PDF]

PLoS ONE, 2013
AMPA receptors-mediators of fast, excitatory transmission and synaptic plasticity in the brain-achieve great functional diversity through interaction with different auxiliary subunits, which alter both the trafficking and biophysical properties of these ...

Copine-6 is a Ca2+ sensor for activity-induced AMPA receptor exocytosis

Cell Reports, 2023
Summary: The recruitment of synaptic α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors underlies the strengthening of neuronal connectivity during learning and memory. This process is triggered by N-methyl-D-aspartate (NMDA) receptor-

AMPA receptors and their minions: auxiliary proteins in AMPA receptor trafficking [PDF]

Cellular and Molecular Life Sciences, 2019
To correctly transfer information, neuronal networks need to continuously adjust their synaptic strength to extrinsic stimuli. This ability, termed synaptic plasticity, is at the heart of their function and is, thus, tightly regulated. In glutamatergic neurons, synaptic strength is controlled by the number and function of AMPA receptors at the ...

Autoinactivation of the stargazin-AMPA receptor complex: subunit-dependency and independence from physical dissociation. [PDF]

PLoS ONE, 2012
Agonist responses and channel kinetics of native α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors are modulated by transmembrane accessory proteins.

Fear Memory Retrieval Is Associated With a Reduction in AMPA Receptor Density at Thalamic to Amygdala Intercalated Cell Synapses

Frontiers in Synaptic Neuroscience, 2021
The amygdala plays a crucial role in attaching emotional significance to environmental cues. Its intercalated cell masses (ITC) are tight clusters of GABAergic neurons, which are distributed around the basolateral amygdala complex.
