The role of AMPA receptors and their antagonists in status epilepticus
Epilepsia, 2018 Status epilepticus (SE) is typically defined as a prolonged self‐sustaining seizure or repeated seizures showing an incomplete recovery between them. SE represents a medical emergency often associated with significant disability, morbidity, and mortality.

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.

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.

Revising Berg-Purcell for finite receptor kinetics [PDF]
, 2021 From nutrient uptake, to chemoreception, to synaptic transmission, many systems in cell biology depend on molecules diffusing and binding to membrane receptors. Mathematical analysis of such systems often neglects the fact that receptors process molecules at finite kinetic rates.

AMPA receptor biogenesis and trafficking
Current Opinion in Neurobiology, 2007 AMPA-type glutamate receptors mediate the majority of fast excitatory transmission in the central nervous system. The trafficking of AMPA receptors to and from synapses alters synaptic strength and has been recognized as a central mechanism underlying various forms of synaptic plasticity.
