G-Protein-coupled or 'metabotropic' glutamate receptors (mGluRs) are a novel heterogenous family of excitatory amino acid receptors. Activation of mGluRs in the rat hippocampus by the mGluR-selective agonist 1S,3R-1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD) leads to multiple changes in second-messenger formation. These include increases in basal phosphoinositide hydrolysis, decreases in forskolin-stimulated cAMP formation, and enhancement of cAMP formation via a potentiation of the effects of endogenous adenosine. These changes in mGluR coupling to phosphoinositide hydrolysis and the formation of cAMP likely reflect the in situ expression of heterogenous populations of mGluRs. A number of electrophysiological studies on the functions of mGluRs in hippocampal circuitry, ontogeny, and cellular functions have also been described. Any or all of these mGluR-mediated changes in second messengers may underlie the reported cellular effects associated with the mGluR activation by 1S,3R-ACPD. However, mGluR agonists that have selectivity for different mGluR second-messenger pathways are needed to sort out the cellular consequences of activating in situ expressed mGluR subtypes linked to specific second-messenger pathways.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015290 Second Messenger Systems Systems in which an intracellular signal is generated in response to an intercellular primary messenger such as a hormone or neurotransmitter. They are intermediate signals in cellular processes such as metabolism, secretion, contraction, phototransduction, and cell growth. Examples of second messenger systems are the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system.

D017470 Receptors, Glutamate Cell-surface proteins that bind glutamate and trigger changes which influence the behavior of cells. Glutamate receptors include ionotropic receptors (AMPA, kainate, and N-methyl-D-aspartate receptors), which directly control ion channels, and metabotropic receptors which act through second messenger systems. Glutamate receptors are the most common mediators of fast excitatory synaptic transmission in the central nervous system. They have also been implicated in the mechanisms of memory and of many diseases.
