Important functional interactions between the metabotropic glutamate 2 (mGlu(2)) and 5-hydroxytryptamine(2A) (5-HT2A) neurotransmitter receptors have been established based on electrophysiological, biochemical and behavioral evidence. Over the last several years, dimerization between 5-HT2A and mGlu(2) receptors has been proposed to account for the functional cross-talk between these two receptors in the prefrontal cortex. The pros and cons for the existence of a heteromeric complex between 5-HT2A and mGlu(2) receptors will be reviewed here. First, the fundamental criteria needing to establish evidence for heteromeric complexes will be reviewed. Then, the in vitro evidence for and against heteromeric complexes between 5-HT2A and mGlu(2) receptors will be discussed in regard to physical and functional interactions. Finally, the data with native in situ mGlu(2) and 5-HT2A receptors will be discussed with respect to whether heteromeric complexes or a simple functional interaction between two distinct GPCRs based on brain network activity is the more simple explanation for a range of in vivo data.
