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

Frontiers 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 ...

Epileptic syndrome in the clinical picture of the diseaseand the level of antibodies to GluR1 subunit of AMPA glutamate receptors in the patients with gliomas in the cerebral hemispheres of a brain

Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2013
The authors examined 92 patients with gliomas in the cerebral hemispheres. The immunoenzyme method was used for semiquantitative assay of the level of autoantibodies to GluR1 subunit of AMPA receptors of glutamate.

Ion channel gradients in the apical tuft region of CA1 pyramidal neurons. [PDF]

PLoS ONE, 2012
Dendritic ion channels play a critical role in shaping synaptic input and are fundamentally important for synaptic integration and plasticity. In the hippocampal region CA1, somato-dendritic gradients of AMPA receptors and the hyperpolarization-activated

Glycine Potentiates AMPA Receptor Function through Metabotropic Activation of GluN2A-containing NMDA Receptors

Frontiers in Molecular Neuroscience, 2016
NMDA receptors are Ca2+-permeable ion channels. The activation of NMDA receptors requires agonist glutamate and co-agonist glycine. Recent evidence indicates that NMDA receptor also has metabotropic function.

Differential involvement of NMDA, AMPA/kainate, and dopamine receptors in the nucleus accumbens core in the acquisition and performance of pavlovian approach behavior [PDF]

, 2001
Stimuli paired with primary rewards can acquire emotional valence and the ability to elicit automatic, Pavlovian approach responses that have been shown to be mediated by the nucleus accumbens. The present experiment investigated the effects of infusions

Desensitization dynamics of the AMPA receptor

Structure, 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 ...

Evidence against AMPA receptor-lacking glutamatergic synapses in the superficial dorsal horn of the rat spinal cord [PDF]

, 2009
Pure NMDA receptor (NMDAr)-mediated EPSCs, thought to correspond to "silent" glutamatergic synapses that lack AMPA receptors (AMPArs), have been observed in superficial spinal dorsal horn of neonatal but not adult rats.

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

Neuroscience 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]

Neuron, 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 ...

Agonist occupancy is essential for forward trafficking of AMPA receptors.

, 2009
Regulated trafficking of AMPA receptors to cell surface and to synapses is an important determinant of neuronal excitability. In the present study, we have addressed the role of agonist binding and desensitization in the early trafficking of glutamate ...
