Cardiac mGluR1 metabotropic receptors in cardioprotection

Using metabotropic glutamate receptors to modulate cocaine's synaptic and behavioral effects: mGluR1 finds a niche.

Group I metabotropic glutamate receptors (mGluR) are important modulators of excitatory synaptic transmission and therefore potential targets for drug development. In several brain regions (ventral tegmental area (VTA), cerebellum, and amygdala), stimulation of mGluR1 selectively inhibits synaptic transmission mediated by calcium-permeable AMPA receptors (CP-AMPARs) and thus produces synaptic d...

Developmental regulation of the hypothalamic metabotropic glutamate receptor mGluR1.

The expression of the metabotropic glutamate receptor mGluR1 was studied with Northern and Western blot analysis, with immunocytochemistry, and with Ca2+ digital imaging in the developing rat hypothalamus. mGluR1 is coupled to a G protein and activation by glutamate and related agonists leads to intracellular phosphotidylinositol hydrolysis and Ca2+ mobilization. mGluR1 RNA could be detected in...

Metabotropic Glutamate Receptors

Metabotropic glutamate receptors (mGluR)s are G-protein-coupled receptors that function as modulators of synaptic function and glutamate transmission. Post-synaptically localized subtype 5 mGlu5 receptors are co-localized with adenosine A2a, dopamine, and N-methyl-D-aspartate (NMDA) receptors and regulate local protein synthesis and messenger RNA (mRNA) translation at synapses, and are thus ide...
