Selective blockade of mGlu5 metabotropic glutamate receptors is protective against methamphetamine neurotoxicity.

Methamphetamine (MA), a widely used drug of abuse, produces oxidative damage of nigrostriatal dopaminergic terminals. We examined the effect of subtype-selective ligands of metabotropic glutamate (mGlu) receptors on MA neurotoxicity in mice. MA (5 mg/kg, i.p.; injected three times, every 2 hr) induced, 5 d later, a substantial degeneration of striatal dopaminergic terminals associated with reac...

Insulin secretion is controlled by mGlu5 metabotropic glutamate receptors.

Recent evidence suggests that metabotropic glutamate (mGlu) receptors are involved in the regulation of hormone secretion in the endocrine pancreas. We report here that endogenous activation of mGlu5 receptors is required for an optimal insulin response to glucose both in clonal beta-cells and in mice. In clonal beta-cells, mGlu5 receptors were expressed at the cell surface and were also found ...

Selective activation of mGlu4 metabotropic glutamate receptors is protective against excitotoxic neuronal death.

Activation of group III metabotropic glutamate receptors (mGluR4, mGluR6, mGluR7, and mGluR8) has been established to be neuroprotective in vitro and in vivo. To disclose the identity of the receptor subtype(s) that exert(s) the protective effect, we have used group III agonists in combination with mGluR4 subtype-deficient mice (-/-). In cortical cultures prepared from wild-type (+/+) mice and ...

Selective blockade of metabotropic glutamate receptor subtype 5 is neuroprotective.

We have used potent and selective non-competitive antagonists of metabotropic glutamate receptor subtype 5 (mGlu5) -- 2-methyl-6-phenylethynylpyridine (MPEP), [6-methyl-2-(phenylazo)-3-pyridinol] (SIB-1757) and [(E)-2-methyl-6-(2-phenylethenyl)pyridine] (SIB-1893) - to examine whether endogenous activation of this particular metabotropic glutamate receptor subtype contributes to neuronal degene...

Group I Metabotropic Glutamate Receptors (mGlu1 and mGlu5)

The metabotropic glutamate (mGlu) receptors are a family of eight G protein-coupled receptors that modulate cell excitability and synaptic transmission in the nervous system. Group I mGlu receptors are generally coupled to Gq stimulation of phospholipase C and the release of intracellular calcium. The physiologic effects of group I mGlu receptors in the brain are diverse and highlight the impor...
