The mGlu7 receptor in schizophrenia - An update and future perspectives

The mGlu7 receptor belongs to the III group of metabotropic glutamatergic (mGlu) receptors and physiologically serves as an “emergency” receptor that is activated by high, almost pathological, glutamate concentrations. Of all mGlu receptors, this receptor is most highly expressed in the brain. Additionally, relatively intense expression of the receptor was found at the periphery, for example in the bowels or in the reproductive system of male mice, but this review will be focused predominantly on its role in the brain.
