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.

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 ...

p97 regulates GluA1 homomeric AMPA receptor formation and plasma membrane expression

open access: yesNature Communications, 2019
AMPA receptors mediate excitatory synaptic transmission and are involved in synaptic plasticity. The authors show that p97 interacts with the GluA1 subunit of AMPA receptors, promotes the formation of GluA1 homomeric AMPA receptors, and regulates AMPA ...

Age-dependent remodelling of ionotropic signalling in cortical astroglia [PDF]

open access: yes, 2011
Cortical astrocytes express fast ionotropic receptors for glutamate and ATP, although their role in neurone-glia communication remains controversial.

Gating Modes in AMPA Receptors [PDF]

open access: yesThe Journal of Neuroscience, 2010
AMPA receptors are ligand-gated ion channels that show multiple conductance levels, indicating that gating of individual AMPA subunits is to some extent independent of the other subunits. To study AMPAR subunit interactions during activation gating, we recorded from single channels in the absence of channel block and desensitization and at negative and

AMPA receptor trafficking and learning [PDF]

open access: yesEuropean Journal of Neuroscience, 2010
AbstractIn the last few years it has become clear that AMPA‐type glutamate neurotransmitter receptors are rapidly transported into and out of synapses to strengthen or weaken their function. The remarkable dynamics of AMPA receptor (AMPAR) synaptic localization provides a compelling mechanism for understanding the cellular basis of learning and memory,

AMPA receptors control fear extinction through an Arc-dependent mechanism [PDF]

open access: yes, 2017
Activity-regulated cytoskeleton-associated protein (Arc) supports fear memory through synaptic plasticity events requiring actin cytoskeleton rearrangements.

Ionotropic Glutamate Receptors in Epilepsy: A Review Focusing on AMPA and NMDA Receptors

open access: yesBiomolecules, 2020
It is widely accepted that glutamate-mediated neuronal hyperexcitation plays a causative role in eliciting seizures. Among glutamate receptors, the roles of N-methyl-D-aspartate (NMDA) and α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA ...

Distinct pharmacological and functional properties of NMDA receptors in mouse cortical astrocytes [PDF]

open access: yes, 2011
Background and purpose Astrocytes of the mouse neocortex express functional NMDA receptors which are not blocked by Mg2+ions. However, study of the pharmacological profile of glial NMDARs and their subunit composition is far from complete ...

Pharmacological characterisation of S 47445, a novel positive allosteric modulator of AMPA receptors.

open access: yesPLoS ONE, 2017
S 47445 is a novel positive allosteric modulator of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptors (AMPA-PAM). S 47445 enhanced glutamate's action at AMPA receptors on human and rat receptors and was inactive at NMDA and ...
