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

Role of ionotropic glutamate receptors in long-term potentiation in rat hippocampal CA1 oriens-lacunosum moleculare interneurons [PDF]
, 2009 Some interneurons of the hippocampus exhibit NMDA receptor-independent long-term potentiation (LTP) that is induced by presynaptic glutamate release when the postsynaptic membrane potential is hyperpolarized.

Differential vesicular sorting of AMPA and GABAA receptors
Proceedings of the National Academy of Sciences of the United States of America, 2016 Significance In neurons most fast excitatory neurotransmission is mediated by AMPA receptors, which cluster at excitatory synapses primarily on dendritic spines. Fast synaptic inhibition is largely mediated by GABAA receptors, which cluster at inhibitory

Dissecting the Activation of AMPA Receptors [PDF]
Biophysical Journal, 2013 Ionotropic glutamate receptors are tetrameric ion channels that are activated by the neurotransmitter glutamate at excitatory synapses. It is known that after the binding of glutamate, the AMPA-subtype of glutamate receptors transits through distinct functional states to become fully activated, however, the conformations sampled by the tetramer during ...

Neurodegeneration in multiple sclerosis
WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023 Chronic demyelination results in impaired axon metabolism and function, ultimately leading to progressive neurological decline. Neuroprotective strategies aim to protect axons from inflammatory‐mediated destruction, thereby improving axonal integrity and clinical disability (Image created in BioRender.com).

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-

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.

Synapse-specific expression of calcium-permeable AMPA receptors in neocortical layer 5 [PDF]
, 2016 In the hippocampus, calcium‐permeable AMPA receptors have been found in a restricted subset of neuronal types that inhibit other neurons, although their localization in the neocortex is less well understood.

AMPA Receptor Activation [PDF]
Neuron, 2004 AMPA receptors are tetramers assembled as a dimer-of-dimers with a 2-fold rotational symmetry in their extracellular domains. Two papers in this issue of Neuron, by Horning and Mayer and Sobolevsky et al., provide complementary data that extend this view and highlight the role of dimers in channel gating.
