AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures
Neurobiology of Disease, 1999 Recent studies indicate that oligodendrocytes are vulnerable to excitotoxic insults mediated by glutamate receptors. The present study was carried out to characterize the type of glutamate receptors triggering cell death in optic nerve oligodendrocyte ...

New Transmembrane AMPA Receptor Regulatory Protein Isoform, γ-7, Differentially Regulates AMPA Receptors [PDF]
The Journal of Neuroscience, 2007 AMPA-type glutamate receptors (GluRs) mediate most excitatory signaling in the brain and are composed of GluR principal subunits and transmembrane AMPA receptor regulatory protein (TARP) auxiliary subunits. Previous studies identified four mammalian TARPs, γ-2 (or stargazin), γ-3, γ-4, and γ-8, that control AMPA receptor trafficking, gating, and ...

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.

A sex difference in the response of the rodent postsynaptic density to synGAP haploinsufficiency [PDF]
, 2020 SynGAP is a postsynaptic density (PSD) protein that binds to PDZ domains of the scaffold protein PSD-95. We previously reported that heterozygous deletion of Syngap1 in mice is correlated with increased steady-state levels of other key PSD proteins that ...

Differential modulation of NMDA and AMPA receptors by cellular prion protein and copper ions
Molecular Brain, 2018 N-Methyl-D-aspartate receptors (NMDARs) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) are two major types of ionotropic glutamate receptors involved in synaptic transmission.

What causes aberrant salience in schizophrenia? A role for impaired short-term habituation and the GRIA1 (GluA1) AMPA receptor subunit. [PDF]
, 2014 The GRIA1 locus, encoding the GluA1 (also known as GluRA or GluR1) AMPA glutamate receptor subunit, shows genome-wide association to schizophrenia. As well as extending the evidence that glutamatergic abnormalities have a key role in the disorder, this ...

PhotonSABER: new tool shedding light on endocytosis and learning mechanisms in vivo
Communicative & Integrative Biology, 2019 In the central nervous system, activity-dependent endocytosis of postsynaptic AMPA-type glutamate receptors (AMPA receptors) is thought to mediate long-term depression (LTD), which is a synaptic plasticity model in various neuronal circuits.

Characterization of Phosphorylation Sites on the Glutamate Receptor 4 Subunit of the AMPA Receptors [PDF]
, 1999 Recent studies have suggested that protein phosphorylation of glutamate receptors may play an important role in synaptic transmission. Specifically, the phosphorylation of AMPA receptors has been implicated in cellular models of synaptic plasticity.

Inhibition of Food Intake by PACAP in the Hypothalamic Ventromedial Nuclei is Mediated by NMDA Receptors [PDF]
, 2014 Central injections of pituitary adenylate cyclase-activating polypeptide (PACAP) into the ventromedial nuclei (VMN) of the hypothalamus produce hypophagia that is dependent upon the PAC1 receptor; however, the signaling downstream of this receptor in the
