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.

Development of AMPA Receptor Aptamers [PDF]
Biophysical Journal, 2010 The α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) subtype of glutamate ion channel receptors plays an essential role in the mammalian brain activities such as memory and learning, whereas the excessive receptor activation has been implicated in neurological diseases such as stroke, epilepsy, and amyotrophic lateral sclerosis.

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

Neuroscience ResearchNMDA 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.

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

Mechanisms of AMPA Receptor Endosomal Sorting [PDF]
Frontiers in Molecular Neuroscience, 2018 The regulation of synaptic AMPA receptors (AMPARs) is critical for excitatory synaptic transmission, synaptic plasticity and the consequent formation of neural circuits during brain development and their modification during learning and memory processes.

Modulating Excitatory Synaptic Neurotransmission: Potential Treatment for Neurological Disease?
Neurobiology of Disease, 1998 Excitatory neurotransmission at many CNS synapses depends upon AMPA-type glutamate receptors. Derangements in AMPA receptor-mediated synaptic transmission may be a contributing factor in neurological and neurodegenerative diseases and could be a target ...

PKA drives an increase in AMPA receptor unitary conductance during LTP in the hippocampus
Nature Communications, 2021 Long-term potentiation at hippocampal CA1 synapses can be due to increasing the number and/or single-channel conductance of AMPA receptors. The authors show that PKA and CaMKII are necessary and together sufficient to increase single channel conductance,
