Psychiatric disorders: Double GPCR trouble

Charlotte Harrison

Glutamatergic and serotoninergic systems have been implicated in psychotic disorders. Gonz|[aacute]|lez-Maeso and colleagues, writing in Nature, show that 5-hydroxytryptamine (5-HT) 2A receptors (5-HT2AR) — through which many existing antipsychotic drugs act — and metabotropic type-2 glutamate receptors (mGluR2) — which are potential new anti-psychotic targets — form complexes that might be involved in schizophrenia.
