Functional interactions between cannabinoid and metabotropic glutamate receptors in the central nervous system

The recent appreciation that two G-protein-coupled receptors, metabotropic glutamate and cannabinoid, are trans-synaptically linked by a small lipid messenger has profound implications, both for control of synaptic transmission and for novel therapeutic strategies. There is much evidence for this assertion and on the significance of this dual receptor cooperation for modulation of synaptic transmission in the central nervous system.
