Abstract
Metabotropic glutamate (mGlu) receptors are found at various levels of the somatosensory/nociceptive signalling pathways from the periphery to the cerebral cortex. The distribution of the receptors in the brain and within and around synapses suggests considerable functional specialisation and specificity. Functional studies in animals indicate that these receptors can participate in or modulate nociceptive processing. Several classes of mGlu receptorβactive agonists and antagonists have been developed, and some of these appear to be effective in animal models of pain. This indicates that development of subtypeβselective mGlu compounds may be a fruitful avenue for the discovery of analgesic agents with novel mechanisms of action. Drug Dev. Res. 54:129β139, 2002.

Western blot analysis of protein extracts from rat liver revealed the presence of the mGlu5 receptor, one of the G-protein-coupled receptors activated by glutamate (named ''metabotropic glutamate receptors'' or mGlu receptors). mGlu5 expression was particularly high in extracts from isolated hepatoc
## Abstract Metabotropic glutamate receptors (mGluRs) play important roles in neurotransmission, neuronal development, synaptic plasticity, and neurological disorders. Recent studies have revealed a sophisticated interplay between mGluRs and protein kinases: activation of mGluRs regulates the activ
