Neuropharmacological Insight from Allosteric Modulation of mGlu Receptors

Publication date: Available online 26 February 2019Source: Trends in Pharmacological SciencesAuthor(s): Branden J. Stansley, P. Jeffrey ConnThe metabotropic glutamate (mGlu) receptors are a family of G-protein-coupled receptors (GPCRs) that regulate cell physiology throughout the nervous system. The potential of mGlu receptors as therapeutic targets has been bolstered by current research that has provided insight into the diverse modes of mGlu activation and signaling. In particular, the allosteric modulation of mGlu receptors represents a major area of focus in studies of basic pharmacology as well as drug development, largely due to the high subtype specificity achievable by targeting allosteric sites on mGlu receptors. These provide sophisticated regulation of neuronal excitability and synaptic transmission to influence behavioral output. Here, we review how these allosteric mechanisms have been leveraged preclinically to demonstrate the therapeutic potential of allosteric modulators for neurological and neuropsychiatric disorders, such as autism, cognitive impairment, Parkinson’s disease (PD), stress, and schizophrenia.
