Parkinson’s disease, epilepsy, and amyotrophic lateral sclerosis—emerging role of AMPA and kainate subtypes of ionotropic glutamate receptors

open access: yesFrontiers in Cell and Developmental Biology, 2023
Ionotropic glutamate receptors (iGluRs) mediate the majority of excitatory neurotransmission and are implicated in various neurological disorders. In this review, we discuss the role of the two fastest iGluRs subtypes, namely, α-amino-3-hydroxy-5-methyl ...

Stargazin Modulation of AMPA Receptors [PDF]

open access: yesCell Reports, 2016
Fast excitatory synaptic signaling in the mammalian brain is mediated by AMPA-type ionotropic glutamate receptors. In neurons, AMPA receptors co-assemble with auxiliary proteins, such as stargazin, which can markedly alter receptor trafficking and gating.

Quantitative analysis of the interaction between NMDA and AMPA receptors in glutamatergic synapses based on mathematical model

open access: yesNeuroscience Research
NMDA and AMPA receptors are co-localized at most glutamatergic synapses, where their numbers and distribution undergo dynamic changes. Glutamate binds to both the NMDA and AMPA receptors.

Nomadic AMPA Receptors and LTP [PDF]

open access: yesNeuron, 1999
What are the broader implications of these two reports? One feature of LTP is its reversibility: once established, application of low-frequency stimulus train can decrease the synaptic strength. When applied to naive synapyses (i.e., in fresh brain slices), such low frequency stimulation induces a long-lasting depression of synaptic responses known as ...

Desensitization dynamics of the AMPA receptor

open access: yesStructure, 2023
To perform their physiological functions, amino methyl propionic acid receptors (AMPARs) cycle through active, resting, and desensitized states, and dysfunction in AMPAR activity is associated with various neurological disorders. Transitions among AMPAR functional states, however, are largely uncharacterized at atomic resolution and are difficult to ...

Auxiliary Subunits Regulate the Dendritic Turnover of AMPA Receptors in Mouse Hippocampal Neurons

open access: yesFrontiers in Molecular Neuroscience, 2021
Different families of auxiliary subunits regulate the function and trafficking of native α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in the central nervous system. While a facilitatory role of auxiliary subunits in ER export and

Transmembrane AMPA receptor regulatory proteins and AMPA receptor function in the cerebellum

open access: yesNeuroscience, 2009
Heterogeneity among AMPA receptor (AMPAR) subtypes is thought to be one of the key postsynaptic factors giving rise to diversity in excitatory synaptic signaling in the CNS. Recently, compelling evidence has emerged that ancillary AMPAR subunits-the so-called transmembrane AMPA receptor regulatory proteins (TARPs)-also play a vital role in influencing ...

AMPA Receptors Bring On the Pain [PDF]

open access: yesNeuron, 2004
The role of Ca(2+)-permeable AMPA receptors in pain processing has not been extensively studied. In this issue of Neuron, Hartmann et al. show that altering the levels of these receptors has consequences for inflammatory pain hypersensitivity but not acute pain processing.

SARM1 is essential for NMDA receptor-dependent endocytosis of AMPA receptors in hippocampal neurons

open access: yesNeuroscience Research
Long-term depression (LTD) is a form of synaptic plasticity thought to be the cellular basis of experience-dependent learning and memory. LTD is caused by an activity-dependent decrease in cell surface α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid

Activation of AMPA Receptors in the Lateral Habenula Produces Anxiolytic Effects in a Rat Model of Parkinson’s Disease

open access: yesFrontiers in Pharmacology, 2022
Background: Parkinson’s disease (PD) is commonly accompanied with anxiety disorder, however, the mechanisms underlying PD-mediated anxiety remain elusive.
