Towards the convergent therapeutic potential of GPCRs in autism spectrum disorders [PDF]

arXiv, 2022
Changes in genetic and/or environmental factors to developing neural circuits and subsequent synaptic functions are known to be a causative underlying the varied socio-emotional behavioural patterns associated with autism spectrum disorders (ASD). Seven transmembrane G protein-coupled receptors (GPCRs) comprising the largest family of cell-surface ...

Direct imaging of lateral movements of AMPA receptors inside synapses [PDF]

EMBO J 22, 18 (15/09/2003) 4656-65, 2007
Trafficking of AMPA receptors in and out of synapses is crucial for synaptic plasticity. Previous studies have focused on the role of endo/exocytosis processes or that of lateral diffusion of extra-synaptic receptors. We have now directly imaged AMPAR movements inside and outside synapses of live neurons using single-molecule fluorescence microscopy ...

Sequences within the C terminus of the metabotropic glutamate receptor 5 (mGluR5) are responsible for inner nuclear membrane localization [PDF]

, 2017
Traditionally, G-protein-coupled receptors (GPCR) are thought to be located on the cell surface where they transmit extracellular signals to the cytoplasm.

LRIT3 is Required for Nyctalopin Expression and Normal ON and OFF Pathway Signaling in the Retina

eNeuro, 2018
The first retinal synapse, photoreceptor→bipolar cell (BC), is both anatomically and functionally complex. Within the same synaptic region, a change in presynaptic glutamate release is sensed by both ON BCs (DBCs) via the metabotropic glutamate receptor ...

From bench to bedside: The mGluR5 system in people with and without Autism Spectrum Disorder and animal model systems

Translational Psychiatry, 2022
The metabotropic glutamate receptor 5 (mGluR5) is a key regulator of excitatory (E) glutamate and inhibitory (I) γ-amino butyric acid (GABA) signalling in the brain. Despite the close functional ties between mGluR5 and E/I signalling, no-one has directly

Genetic Deletion of mGlu3 Metabotropic Glutamate Receptors Amplifies Ischemic Brain Damage and Associated Neuroinflammation in Mice

Frontiers in Neurology, 2021
Backgroud: Type-3 metabotropic glutamate (mGlu3) receptors are found in both neurons and glial cells and regulate synaptic transmission, astrocyte function, and microglial reactivity.

N-acetyl-cysteine, a drug that enhances the endogenous activation of group-II metabotropic glutamate receptors, inhibits nociceptive transmission in humans. [PDF]

, 2015
Emerging research seeking novel analgesic drugs focuses on agents targeting group-II metabotropic glutamate receptors (mGlu2 and mGlu3 receptors). N-Acetylcysteine (NAC) enhances the endogenous activation of mGlu2/3 receptors by activating the glial ...

Design, synthesis, and characterization of [18F]mG2P026 as a high contrast PET imaging ligand for metabotropic glutamate receptor 2

bioRxiv, 2021
An array of triazolopyridines based on JNJ-46356479 (6) were synthesized as potential PET imaging ligands for metabotropic glutamate receptor 2 (mGluR2) in the brain.

Grape seed proanthocyanidin extract inhibits glutamate-induced cell death through inhibition of calcium signals and nitric oxide formation in cultured rat hippocampal neurons

BMC Neuroscience, 2011
Background Proanthocyanidin is a polyphenolic bioflavonoid with known antioxidant activity. Some flavonoids have a modulatory effect on [Ca2+]i. Although proanthocyanidin extract from blueberries reportedly affects Ca2+ buffering capacity, there are no ...

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex [PDF]

Physiological Reports, 30th Dec. 2016, Vol. 4 no. e13051, 2016
NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability. There are different NMDA receptor subtypes which differ in their single-channel conductance.
