Direct interaction enables cross-talk between ionotropic and group I metabotropic glutamate receptors.

Glutamate ionotropic and metabotropic receptors affect feed intake in broiler cockerels

Cross-talk between glutamate and nucleotide receptors in cerebellar granule neurons in culture

ATP elicits Ca transients in cultured cerebellar granule neurons acting through specific ionotropic (P2X) and metabotropic (P2Y) purinergic receptors. In these neurons, application of L-Glutamate (L-Glu) immediately before ATP induced a prolonged reduction of ATP-mediated responses that remains at least 5 minutes after L-Glu wash out. alpha-amino-3-hydro-5-methyl-4-isoxazolpropionic acid (AMPA)...

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...

Cross talk between metabotropic and ionotropic glutamate receptor-mediated signaling in parallel fiber-induced inositol 1,4,5-trisphosphate production in cerebellar Purkinje cells.

In many excitatory glutamatergic synapses, both ionotropic glutamate receptors (iGluRs) and metabotropic glutamate receptors (mGluRs) are closely distributed on the postsynaptic membrane. However, the functional significance of the close distribution of the two types of glutamate receptors has not been fully clarified. In this study, we examined the functional interaction between iGluR and mGlu...

(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...
