Ageing reduces the number of OPCs and their ‘stemness’. Genomic analysis resolved key mechanisms underpinning the age related decline in OPCs, most notably reduced expression of Gpr17 in a subpopulation of differentiation committed OPCs. Pharmacogenomics identified small molecules that have the potential to rejuvenate OPCs and promote myelination and ...

Stargazin controls the pharmacology of AMPA receptor potentiators [PDF]
Glutamate is the major excitatory neurotransmitter in brain, and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptors (AMPARs) mediate the majority of postsynaptic depolarization. AMPAR ion channels display rapid gating, and their deactivation and desensitization determine the timing of synaptic transmission.

Synaptic activity mediates information storage and memory consolidation in the brain and requires a fast de novo synthesis of mRNAs in the nucleus and proteins in synapses. Intracellular localization of a protein can be achieved by mRNA trafficking and localized translation. Activity‐regulated cytoskeleton‐associated protein (Arc) is a master regulator

Molecular Mechanism of AMPA Receptor Modulation by TARP/Stargazin [PDF]
AMPA receptors (AMPARs) mediate the majority of fast excitatory transmission in the brain and critically contribute to synaptic plasticity and pathology. AMPAR trafficking and gating are tightly controlled by auxiliary transmembrane AMPAR regulatory proteins (TARPs).

Calpain-mediated regulation of stargazin in adult rat brain [PDF]
Changes in AMPA receptors have been proposed to underlie changes in synaptic efficacy in hippocampus and other brain structures. Calpain activation has also been discussed as a potential mechanism to produce lasting modifications of synaptic structure and function.

Screening for AMPA receptor auxiliary subunit specific modulators. [PDF]
AMPA receptors (AMPAR) are ligand gated ion channels critical for synaptic transmission and plasticity. Their dysfunction is implicated in a variety of psychiatric and neurological diseases ranging from major depressive disorder to amyotrophic lateral ...

AMPA receptor GluA2 subunit defects are a cause of neurodevelopmental disorders [PDF]
AMPA receptors (AMPARs) are tetrameric ligand-gated channels made up of combinations of GluA1-4 subunits encoded by GRIA1-4 genes. GluA2 has an especially important role because, following post-transcriptional editing at the Q607 site, it renders ...

Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously

The AMPA glutamate receptor (AMPAR) is the major type of synaptic excitatory ionotropic receptor in the brain. AMPARs have four different subunits, GluA1–4 (each encoded by different genes, Gria1, Gria2, Gria3 and Gria4), that can form distinct ...

Aggregation Limits Surface Expression of Homomeric GluA3 Receptors [PDF]
AMPA receptors are glutamate-gated cation channels assembled from GluA1-4 subunits and have properties that are strongly dependent on the subunit composition.
