Genetic and Pharmacological Inhibition of Metabotropic Glutamate Receptor Signalling Extends Lifespan in Drosophila. [PDF]
We show that genetic and pharmacological inhibition of the metabotropic glutamate receptor, DmGluRA extends Drosophila lifespan, improves stress tolerance and alters early‐life locomotion. Several markers indicative of reduced ribosomal biogenesis, a hallmark of longevity, were also detected in these flies.

Acute Alcohol-Induced Changes Measured With Metabotropic Glutamate Receptor 5 Positron Emission Tomography. [PDF]
This proof‐of‐concept study provides evidence that acute alcohol administration reduces mGluR5 availability and increases relative blood flow in the human brain, as measured by [11C]ABP688 PET. The observed effects align with preclinical evidence of alcohol‐induced glutamate release.

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 ...

Kainate receptor modulation by NETO2 [PDF]
Glutamate-gated kainate receptors (KARs) are ubiquitous in the central nervous system of vertebrates, mediate synaptic transmission on post-synapse, and modulate transmitter release on pre-synapse. In the brain, the trafficking, gating kinetics, and pharmacology of KARs are tightly regulated by Neuropilin and tolloid-like proteins (Netos).

Emotional Impairment and Persistent Upregulation of mGlu5 Receptor following Morphine Abstinence: Implications of an mGlu5-MOPr Interaction. [PDF]
BACKGROUND: A difficult problem in treating opioid addicts is the maintenance of a drug-free state because of the negative emotional symptoms associated with withdrawal, which may trigger relapse.

Abstract Autism spectrum disorders (ASDs) are diagnosed in 1/100 children worldwide, based on two core symptoms: deficits in social interaction and communication, and stereotyped behaviours. G protein‐coupled receptors (GPCRs) are the largest family of cell‐surface receptors that transduce extracellular signals to convergent intracellular signalling ...

Group I metabotropic glutamate receptors are expressed in the chicken retina and by cultured retinal amacrine cells [PDF]
Glutamate is well established as an excitatory neurotransmitter in the vertebrate retina. Its role as a modulator of retinal function, however, is poorly understood.

Gαq signalling from endosomes: A new conundrum
Abstract G‐protein‐coupled receptors (GPCRs) constitute the largest family of membrane receptors, and are involved in the transmission of a variety of extracellular stimuli such as hormones, neurotransmitters, light and odorants into intracellular responses.

Uncoupling of the endocannabinoid signalling complex in a mouse model of fragile X syndrome [PDF]
Fragile X syndrome, the most commonly known genetic cause of autism, is due to loss of the fragile X mental retardation protein, which regulates signal transduction at metabotropic glutamate receptor-5 in the brain.

Optical control of metabotropic glutamate receptors [PDF]
G protein-coupled receptors (GPCRs), the largest family of membrane signaling proteins, respond to neurotransmitters, hormones and small environmental molecules. The neuronal function of many GPCRs has been difficult to resolve because of an inability to gate them with subtype specificity, spatial precision, speed and reversibility. To address this, we
