Functional modulation of AMPA receptors by transmembrane AMPA receptor regulatory proteins

Neuroscience, 2009
The AMPA receptors are ligand-gated ion channels belonging to the family of ionotropic glutamate receptors. They play an essential role in fast excitatory synaptic transmission in the CNS of vertebrates. Their activity-dependent directed transport and fast turnover at the plasma membrane contribute to synaptic plasticity and require numerous ...

AMPA Receptor Cycling in the Synapse

Science's STKE, 2004
Ionotropic glutamate receptors (GluRs) are involved in mediating signaling in response to synaptic activity. In addition to converting the chemical signal released from the presynaptic terminal to an electrical response in the postsynaptic neuron, these receptors are critically involved in activity-dependent, long-term changes in synaptic strength and,

Inhibitors of AMPA and Kainate Receptors

Current Medicinal Chemistry, 2001
The glutamate receptor system is implicated in the development and maintenance of epileptic seizures, and animal studies have disclosed potent anticonvulsant activity of a number of inhibitors of AMPA and/or kainate (KA) receptor activity. These results make such inhibitors potential future antiepileptic drugs.

Rapid spine delivery and redistribution of AMPA receptors after synaptic NMDA receptor activation.

Science, 1999
To monitor changes in alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptor distribution in living neurons, the AMPA receptor subunit GluR1 was tagged with green fluorescent protein (GFP).

Sensitivity of AMPA receptors to pentobarbital

European Journal of Pharmacology: Molecular Pharmacology, 1994
The inhibitory effects of pentobarbital on various AMPA receptors expressed (GluR1, GluR3, GluR1/3, GluR1/2, and GluR2/3) in Xenopus oocytes were examined. Combinations of AMPA receptor subunits that included GluR2 demonstrated a much higher sensitivity to blockade by this barbiturate and the apparent co-operativity of the interaction of pentobarbital ...

Stargazin and the AMPA receptor

Science, 2016
Structural Biology AMPA-subtype ionotropic glutamate receptors (AMPARs) mediate fast excitatory neurotransmission and contribute to higher cognitive processes such as learning and memory. In the brain, AMPARs exist as protein-protein complexes with various auxiliary subunits that tightly control AMPAR trafficking, gating, and pharmacology.

A family of AMPA-selective glutamate receptors.

Science, 1990
Four cloned cDNAs encoding 900-amino acid putative glutamate receptors with approximately 70 percent sequence identity were isolated from a rat brain cDNA library.

The AMPA receptors of auditory neurons

Hearing Research, 2000
The ionotropic glutamate receptor (GluR) subtype known as the AMPA receptor, which mediates rapid excitatory synaptic transmission in many regions of the nervous system, is composed of four different protein subunits, termed GluRs 1-4. The functional properties of each AMPA receptor are determined by the relative levels of GluRs 1-4 and by post ...

In Search of Novel AMPA Potentiators

Recent Patents on CNS Drug Discovery, 2006
Glutamate is the major excitatory neurotransmitter in the brain. Amongst ionotropic receptors responding to glutamate, the AMPA subtype has been considered as essential for the fast excitatory neurotransmission in the central nervous system and the expression and maintenance of long-term potentiation.
