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

open access: yesFrontiers 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.

Auxiliary Subunits Control Function and Subcellular Distribution of AMPA Receptor Complexes in NG2 Glia of the Developing Hippocampus

open access: yesFrontiers in Cellular Neuroscience, 2021
Synaptic and axonal glutamatergic signaling to NG2 glia in white matter is critical for the cells’ differentiation and activity dependent myelination. However, in gray matter the impact of neuron-to-NG2 glia signaling is still elusive, because most of ...

AMPA receptors: Role in brain injury [PDF]

open access: yes, 2003
Glutamate can be considered a 'Jekyll and Hyde' molecule that serves an essential role as neurotransmitter whilst having potentially damaging, neurotoxic effects.

Testing of the therapeutic efficacy and safety of AMPA receptor RNA aptamers in an ALS mouse model

open access: yesLife Science Alliance, 2022
RNA aptamers designed to block AMPA receptors effectively reduce progression of motor dysfunction, improve TDP-43 pathology, and prevent death of motor neurons in AR2 mice, a mouse model of sporadic ALS, without adverse effects.

SAD-B modulates epileptic seizure by regulating AMPA receptors in patients with temporal lobe epilepsy and in the PTZ-induced epileptic model [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2020
α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are the predominant mediators of glutamate-induced excitatory neurotransmission.

Distinct neurexin-cerebellin complexes control AMPA- and NMDA-receptor responses in a circuit-dependent manner

open access: yeseLife, 2022
At CA1→subiculum synapses, alternatively spliced neurexin-1 (Nrxn1SS4+) and neurexin-3 (Nrxn3SS4+) enhance NMDA-receptors and suppress AMPA-receptors, respectively, without affecting synapse formation.

Activation of acid‐sensing ion channels by carbon dioxide regulates amygdala synaptic protein degradation in memory reconsolidation

open access: yesMolecular Brain, 2021
Reconsolidation has been considered a process in which a consolidated memory is turned into a labile stage. Within the reconsolidation window, the labile memory can be either erased or strengthened.

Sequential Activation of AMPA Receptors and Glial Cells in a Pain Model of Lumbar Spine Disc Herniation [PDF]

open access: yesAnnals of Rehabilitation Medicine, 2020
Objective To investigate the glial cell and AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor activity after surgery for disc herniation pain model.

Potentiation of glycine-gated NR1/NR3A NMDA receptors relieves Ca2+-dependent outward rectification [PDF]

open access: yes, 2010
Glycine has diverse functions within the mammalian central nervous system. It inhibits postsynaptic neurons via strychnine-sensitive glycine receptors (GlyRs) and enhances neuronal excitation through co-activation of N-methyl-D-aspartate (NMDA) receptors.

AMPA Receptor-Mediated Ca2+ Transients in Mouse Olfactory Ensheathing Cells

open access: yesFrontiers in Cellular Neuroscience, 2019
Ca2+ signaling in glial cells is primarily triggered by metabotropic pathways and the subsequent Ca2+ release from internal Ca2+ stores. However, there is upcoming evidence that various ion channels might also initiate Ca2+ rises in glial cells by Ca2 ...
