mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]
, 2018 Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

AMPA-ergic regulation of amyloid-β levels in an Alzheimer’s disease mouse model
Molecular Neurodegeneration, 2018 Extracellular aggregation of the amyloid-β (Aβ) peptide into toxic multimers is a key event in Alzheimer’s disease (AD) pathogenesis. Aβ aggregation is concentration-dependent, with higher concentrations of Aβ much more likely to form toxic species.

Superactivation of AMPA receptors by auxiliary proteins [PDF]
Nature Communications, 2016 AbstractGlutamate receptors form complexes in the brain with auxiliary proteins, which control their activity during fast synaptic transmission through a seemingly bewildering array of effects. Here we devise a way to isolate the activation of complexes using polyamines, which enables us to show that transmembrane AMPA receptor regulatory proteins ...

Allosteric competition and inhibition in AMPA receptors
Nature Structural & Molecular Biology, 2023 AbstractExcitatory neurotransmission is principally mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-subtype ionotropic glutamate receptors (AMPARs). Negative allosteric modulators are therapeutic candidates that inhibit AMPAR activation and can compete with positive modulators to control AMPAR function through unresolved ...
