Removal of AMPA receptors (AMPARs) from synapses is preceded by transient endocytosis of extrasynaptic AMPARs [PDF]
AMPA receptors (AMPARs) are dynamically regulated at synapses, but the time course and location of their exocytosis and endocytosis are not known. Therefore, we have used ecliptic pHluorin-tagged glutamate receptor 2 to visualize changes in AMPAR surface

Regulation of AMPA receptors in spinal nociception
The functional properties of α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptors in different brain regions, such as hippocampus and cerebellum, have been well studied in vitro and in vivo. The AMPA receptors present a unique characteristic

Single-Particle Tracking of AMPA Receptor-Containing Vesicles
AMPA-type receptors are transported large distances to support synaptic plasticity at distal dendritic locations. Studying the motion of AMPA receptor+ vesicles can improve our understanding of the mechanisms that underlie learning and memory ...

The tetraspanin TSPAN5 regulates AMPAR exocytosis by interacting with the AP4 complex
Intracellular trafficking of AMPA receptors is a tightly regulated process which involves several adaptor proteins, and is crucial for the activity of excitatory synapses both in basal conditions and during synaptic plasticity.

Differential localization of glutamate receptor subunits at the drosophila neuromuscular junction [PDF]
The subunit composition of postsynaptic neurotransmitter receptors is a key determinant of synaptic physiology. Two glutamate receptor subunits, Drosophila glutamate receptor IIA (DGluRIIA) and DGluRIIB, are expressed at the Drosophila neuromuscular ...

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 ...

Pharmacological analysis of ionotropic glutamate receptor function in neuronal circuits of the zebrafish olfactory bulb. [PDF]
Although synaptic functions of ionotropic glutamate receptors in the olfactory bulb have been studied in vitro, their roles in pattern processing in the intact system remain controversial.

P2X receptor trafficking in neurons is subunit specific [PDF]
P2X receptors within the CNS mediate excitatory synaptic transmission and also act presynaptically to modulate neurotransmitter release. We have studied the targeting and trafficking of P2X4 and P2X2 receptors heterologously expressed in cultured ...
