Protein Kinase Cβ and δ Selectively Phosphorylate Odorant and Metabotropic Glutamate Receptors

Metabotropic glutamate receptors and their ligands applications in neurological and psychiatric disorders

Metabotropic glutamate receptors (mGluRs) consist of a large family of G-protein coupled receptors that are critical for regulating normal neuronal function in the central nervous system. The wide distribution and diverse physiological roles of various mGluR subtypes make them highly attractive targets for the treatment of a number of neurological and psychiatric disorders. The discovery of ...

Glutamate ionotropic and metabotropic receptors affect feed intake in broiler cockerels

A novel Ca2+-independent signaling pathway to extracellular signal-regulated protein kinase by coactivation of NMDA receptors and metabotropic glutamate receptor 5 in neurons.

The specification and organization of glutamatergic synaptic transmission require the coordinated interaction among glutamate receptors and their synaptic adaptor proteins closely assembled in the postsynaptic density (PSD). Here we investigated the interaction between NMDA receptors and metabotropic glutamate receptor 5 (mGluR5) in the integral regulation of extracellular signal-regulated prot...

Regulation of Group I Metabotropic Glutamate Receptors by MAPK/ERK in Neurons.

Group I metabotropic glutamate receptors (mGluR1 and mGluR5 subtypes) are regulated by protein kinases. A recent focus is mitogen-activated protein kinases (MAPK). A prototypic subclass of MAPKs, extracellular signal-regulated kinases (ERK), is densely expressed in adult brain postmitotic neurons. This kinase resides in not only the cytoplasm around the nucleus, also the neuronal peripheral str...

(S)- 3,5-Dihydroxyphenylglycine )an agonist for group I metabotropic glutamate receptors( induced synaptic potentiation at excitatory synapses on fast spiking GABAergic cells in visual cortex

Introduction: (S)- 3,5-Dihydroxyphenylglycine (DHPG) is an agonist for group I metabotropic glutamate receptors. DHPG-induced synaptic depression of excitatory synapses on hippocampal pyramidal neurons is well known model for synaptic plasticity studies. The aim of the present study was to examine the effects of DHPG superfusion on excitatory synapses on pyramidal and fast-spiking GABAergic cel...
