Modulation of AMPA Receptors by Nitric Oxide in Nerve Cells
Nitric oxide (NO) is a gaseous molecule with a large number of functions in living tissue. In the brain, NO participates in numerous intracellular mechanisms, including synaptic plasticity and cell homeostasis.

AMPA Receptors Bring On the Pain [PDF]
The role of Ca(2+)-permeable AMPA receptors in pain processing has not been extensively studied. In this issue of Neuron, Hartmann et al. show that altering the levels of these receptors has consequences for inflammatory pain hypersensitivity but not acute pain processing.

Nomadic AMPA Receptors and LTP [PDF]
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 ...

RNA aptamers for AMPA receptors. [PDF]
RNA aptamers are single-stranded RNA molecules, and they are selected against a target of interest so that they can bind to and modulate the activity of the target, such as inhibiting the target activity, with high potency and selectivity. Antagonists, such as RNA aptamers, acting on AMPA receptors, a major subtype of ionotropic glutamate receptors ...

Reconsolidation has been considered a process in which a consolidated memory is turned into a labile stage. Within the reconsolidation window, the labile memory can be either erased or strengthened.

Architecture and subunit arrangement of native AMPA receptors elucidated by cryo-EM
Diversity in ion channel complexes AMPA receptors are glutamate activated ion channels that mediate fast synaptic transmission in the nervous system and play a key role in learning and memory.

AMPA receptor trafficking and learning [PDF]
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,

AMPA Receptor-Mediated Ca2+ Transients in Mouse Olfactory Ensheathing Cells
Ca2+ signaling in glial cells is primarily triggered by metabotropic pathways and the subsequent Ca2+ release from internal Ca2+ stores. However, there is upcoming evidence that various ion channels might also initiate Ca2+ rises in glial cells by Ca2 ...

Gating Modes in AMPA Receptors [PDF]
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
