Heterodimerization of calcium sensing receptors with metabotropic glutamate receptors in neurons.

(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...

Cooperative signaling between homodimers of metabotropic glutamate receptors 1 and 5.

Metabotropic glutamate receptors (mGluRs) function as dimers. Recent work suggests that mGluR1 and mGluR5 may physically interact, but the nature and functional consequences of this relationship have not been addressed. In this study, the functional and pharmacological consequences of this interaction were investigated. Using heterologous expression of mGluR cDNA in rat sympathetic neurons from...

Glutamate ionotropic and metabotropic receptors affect feed intake in broiler cockerels

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 ...

Ionotropic Glutamate Receptors and their Role in Neurological Diseases

Glutamate is extensively and relatively uniformly distributed in the central nervous system (CNS) and its effects mediated by two distinct groups of receptors including Ionotropic and metabotropic glutamate receptors. Concentration of glutamate in the nervous system is much higher than in other tissues. Glutamate receptors play an important role in synaptic transmission, neural plasticity and n...
