AMPA receptor diversity and dynamics during excitatory synaptic transmission
… into a pre and postsynaptic side. By employing AMPA receptors (AMPARs), the postsynaptic cell can respond to presynaptic glutamate release with millisecond-timescale precision. The diversity of AMPAR subtypes across the brain is vast, with each subtype providing unique signalling properties. The …

Single-molecule FRET analysis of the dynamics of AMPA receptor
… of GluR2, a subunit of the ionotropic glutamate/AMPA receptor. The GluR2-SIS2 molecule was determined to have a more open cleft when the natural ligand glutamate is not present as compared to when glutamate is bound to the molecule. The apo and Glutamate-bound GluR2-S1S2 molecules in solution …

Identification and functional characterisation of synaptic AMPA receptor-interacting proteins
… synaptic transmission is mediated primarily by AMPA-type glutamate receptors (AMPARs), and is crucial for the transfer and storage of information in the brain. The AMPAR engages in numerous protein interactions, modulating receptor trafficking, channel gating, synaptic positioning, and …

Morfiinin vaikutukset ehdollistetussa paikkahakuisuuskokeessa AMPA-tyypin glutamaattireseptorin GluA1-alayksikön poistogeenisillä hiirillä
… in the efficacy of their action. Glutamatergic AMPA receptor and especially its GluA1 subunit are thought to be included in the neurobiological mechanisms related to drug addiction. Compulsive drug craving and relapses to drug use after a period of abstinence are central problems among people …

The Effect of L-Proline on Two Recombinant AMPA Glutamate Receptors
… concentrations of l-proline at two recombinant AMPA receptors: homomeric GluR1 and heteromeric GluR1/2. Dose response to l-proline (concentrations of 3 µM – 10 mM) at homomeric GluR1 and heteromeric GluR1/2 receptors were determined and compared to saturating concentration of glutamate (10 mM). …

MOLECULAR FACTORS THAT INFLUENCE THE BINDING OF AGONISTS TO AMPA RECEPTORS
<p>AMPA receptors mediate excitatory synaptic transmission throughout the central nervous system via activation by their natural agonist glutamate. Several other molecules have been recognized as receptor agonist or antagonist, and recently allosteric modulators have been developed that potentiate …

Molecular alterations of AMPA receptors and their effects on hippocampus dependent tasks
… (GluR-A-/-) mice showed that GluR-A containing AMPA receptors are required for working memory, strengthened by those findings that expression of a transgenic GluR-A subunit in the forebrain of GluR-A-/- mice partially rescues this memory deficit. In a spatial reference memory task GluR-A-/- mice …

Requirement for AMPA receptor endocytosis and long-term depression in ocular dominance plasticity
… propionic acid receptors (AMPARs). Although it has been shown that MD similarly causes a loss of AMPARs from visual cortical synapses, the contribution of this change to OD plasticity has not been established. Here we develop a herpes-simplex virus (HSV) vector to express a …
