Testing of the therapeutic efficacy and safety of AMPA receptor RNA aptamers in an ALS mouse model
Life Science Alliance, 2022 RNA aptamers designed to block AMPA receptors effectively reduce progression of motor dysfunction, improve TDP-43 pathology, and prevent death of motor neurons in AR2 mice, a mouse model of sporadic ALS, without adverse effects.

Gating Modes in AMPA Receptors [PDF]
The Journal of Neuroscience, 2010 AMPA receptors are ligand-gated ion channels that show multiple conductance levels, indicating that gating of individual AMPA subunits is to some extent independent of the other subunits. To study AMPAR subunit interactions during activation gating, we recorded from single channels in the absence of channel block and desensitization and at negative and

Control of AMPA receptor activity by the extracellular loops of auxiliary proteins
eLife, 2017 At synapses throughout the mammalian brain, AMPA receptors form complexes with auxiliary proteins, including TARPs. However, how TARPs modulate AMPA receptor gating remains poorly understood. We built structural models of TARP-AMPA receptor complexes for

Selective disruption of stimulus-reward learning in glutamate receptor gria 1 knockout mice. [PDF]
, 2003 Glutamatergic neurotransmission via AMPA receptors has been an important focus of studies investigating neuronal plasticity. AMPA receptor glutamate receptor 1 (GluR1) subunits play a critical role in long-term potentiation (LTP).

AMPA receptor trafficking and learning [PDF]
European Journal of Neuroscience, 2010 AbstractIn the last few years it has become clear that AMPA‐type glutamate neurotransmitter receptors are rapidly transported into and out of synapses to strengthen or weaken their function. The remarkable dynamics of AMPA receptor (AMPAR) synaptic localization provides a compelling mechanism for understanding the cellular basis of learning and memory,

Stargazin Dephosphorylation Mediates Homeostatic Synaptic Downscaling of Excitatory Synapses
Frontiers in Molecular Neuroscience, 2018 Synaptic scaling is a form of homeostatic plasticity that is critical for maintaining neuronal activity within a dynamic range, and which alters synaptic strength through changes in postsynaptic AMPA-type glutamate receptors.

Microglia shape presynaptic properties at developing glutamatergic synapses [PDF]
, 2019 Deficient neuron-microglia signaling during brain development is associated with abnormal synaptic maturation. However, the precise impact of deficient microglia function on synaptic maturation and the mechanisms involved remain poorly defined.

C-Terminal truncation of NR2A subunits impairs synaptic but not extrasynaptic localization of NMDA receptors [PDF]
, 2000 NMDA receptors interact via the extended intracellular C-terminal domain of the NR2 subunits with constituents of the postsynaptic density for purposes of retention, clustering, and functional regulation at central excitatory synapses.
