Metabotropic glutamate receptors in cancer [PDF]

Neuropharmacology, 2017
Metabotropic glutamate receptors (mGluRs) are widely known for their roles in synaptic signaling. However, accumulating evidence suggests roles of mGluRs in human malignancies in addition to synaptic transmission. Somatic cell homeostasis presents intriguing possibilities of mGluRs and glutamate signaling as novel targets for human cancers.

Metabotropic glutamate receptor trafficking [PDF]

Molecular and Cellular Neuroscience, 2018
The metabotropic glutamate receptors (mGlu receptors) are G protein-coupled receptors that bind to the excitatory neurotransmitter glutamate and are important in the modulation of neuronal excitability, synaptic transmission, and plasticity in the central nervous system.

Characterizing Spatial Associations Between GluCEST MRI and Neurotransmitter Receptor Density in the Human Cortex. [PDF]

Hum Brain Mapp
We leveraged in vivo 7T GluCEST MRI and normative PET receptor maps to examine the spatial covariation between cortical glutamate levels and receptor expression. GluCEST signal showed positive spatial associations with NMDA and GABAA, but not mGluR5. These findings enhance our understanding of GluCEST and glutamate‐receptor dynamics across the cortex ...

Intra- and Extracellular Pillars of a Unifying Framework for Homeostatic Plasticity: A Crosstalk Between Metabotropic Receptors and Extracellular Matrix

Frontiers in Cellular Neuroscience, 2019
In the face of chronic changes in incoming sensory inputs, neuronal networks are capable of maintaining stable conditions of electrical activity over prolonged periods of time by adjusting synaptic strength, to amplify or dampen incoming inputs ...

Metabotropic Glutamate Receptors and Epileptogenesis

Epilepsy Currents, 2002
Activation of metabotropic glutamate receptors (mGluRs) often produces long-lasting effects on the excitability of cortical neurons. For example, mGluR stimulation induces long-term potentiation or depression of excitatory synaptic transmission in the hippocampus.

Metabotropic Glutamate Receptors Inhibit Microglial Glutamate Release

ASN Neuro, 2012
Pro-inflammatory stimuli evoke an export of glutamate from microglia that is sufficient to contribute to excitotoxicity in neighbouring neurons. Since microglia also express various glutamate receptors themselves, we were interested in the potential ...

Phased Treatment Strategies for Cerebral Ischemia Based on Glutamate Receptors

Frontiers in Cellular Neuroscience, 2019
Extracellular glutamate accumulation following cerebral ischemia leads to overactivation of glutamate receptors, thereby resulting in intracellular Ca2+ overload and excitotoxic neuronal injury. Multiple attempts have been made to counteract such effects

Conformational pathway provides unique sensitivity to a synaptic mGluR

Nature Communications, 2019
Metabotropic glutamate receptors (mGluRs) are dimeric G-protein–coupled receptors that operate at neural synapses. Here authors use FRET assays in live cells to monitor mGluR2/7’s activation and reveal how heterodimerization can alter the glutamate ...

Researching glutamate – induced cytotoxicity in different cell lines: a comparative/, collective analysis/study

Frontiers in Cellular Neuroscience, 2015
Although glutamate is one of the most important excitatory neurotransmitters of the central nervous system, its excessive extracellular concentration leads to uncontrolled continuous depolarization of neurons, a toxic process called, excitotoxicity.

Inhibition of metabotropic glutamate receptor III facilitates sensitization to alkylating chemotherapeutics in glioblastoma

Cell Death and Disease, 2021
Glioblastoma (GBM), the most malignant tumor of the central nervous system, is marked by its dynamic response to microenvironmental niches. In particular, this cellular plasticity contributes to the development of an immediate resistance during tumor ...
