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.

G protein-coupled receptor signalling in astrocytes in health and disease: A focus on metabotropic glutamate receptors [PDF]
Work published over the past 10–15 years has caused the neuroscience community to engage in a process of constant re-evaluation of the roles of glial cells in the mammalian central nervous system.

Loss of metabotropic glutamate receptor 2 escalates alcohol consumption. [PDF]
Significance Gene identification for complex behavioral traits, alcoholism in particular, has been largely unsuccessful, in part because of the rarity of many causative variants and the heterogeneity and small effect size of the causal loci. Artificially selected animals may be valuable in gene identification.

Group II metabotropic glutamate receptor type 2 allosteric potentiators prevent sodium lactate-induced panic-like response in panic-vulnerable rats [PDF]
Rats with chronic inhibition of GABA synthesis by infusion of l-allyglycine, a glutamic acid decarboxylase inhibitor, into their dorsomedial/perifornical hypothalamus are anxious and exhibit panic-like cardio-respiratory responses to treatment with ...

Positive allosteric modulators of metabotropic glutamate 2 receptors in schizophrenia treatment [PDF]
The past two decades have witnessed a rise in the 'NMDA receptor hypofunction' hypothesis for schizophrenia, a devastating disorder that affects around 1% of the population worldwide. A variety of presynaptic, postsynaptic, and regulatory proteins involved in glutamatergic signaling have thus been proposed as potential therapeutic targets.

Oxidative stress and glutamate excretion in alcoholic steatosis: Metabolic synapse between hepatocyte and stellate cell [PDF]
Chronic alcohol consumption induces the development of alcoholic steatosis in the liver, which is one of the most widespread liver diseases worldwide. During general alcohol metabolism, hepatocytes generate mitochondria- and cytochrome P450 2E1 (CYP2E1 ...

Astrocyte activation in the anterior cingulate cortex and altered glutamatergic gene expression during paclitaxel-induced neuropathic pain in mice [PDF]
Spinal astrocyte activation contributes to the pathogenesis of paclitaxel-induced neuropathic pain (PINP) in animal models. We examined glial fibrillary acidic protein (GFAP; an astrocyte marker) immunoreactivity and gene expression of GFAP, glutamate ...

Apo-state structure of the metabotropic glutamate receptor 5 transmembrane domain obtained using a photoswitchable ligand. [PDF]
Abstract Metabotropic glutamate receptor 5 (mGlu5) is implicated in various neurodegenerative disorders, making it an attractive drug target. Although several ligand‐bound crystal structures of mGlu5 exist, their apo‐state crystal structure remains unknown.

Targeting mGlu5 metabotropic glutamate receptors in the treatment of cognitive dysfunction in a mouse model of phenylketonuria [PDF]
We studied group-I metabotropic glutamate (mGlu) receptors in Pah(enu2) (ENU2) mice, which mimic the genetics and neurobiology of human phenylketonuria (PKU), a metabolic disorder characterized, if untreated, by autism, and intellectual disability (ID ...
