21881873 data support the idea that glutamate release in the vental tegmental area(VTA) is critically involved in cocaine-induced reinstatement; loss of mGluR2/3-mediated regulation of glutamate release in the VTA may critically contribute to the risk of relapse
21173788 Suggest a genetic association exists between SNPs in several genes, such as HTR2A and NRG1, and response to mGlu2/3 agonist LY2140023 treatment in schizophrenia.
20211215 Our results suggested that GRM2 may play a role in the pathophysiology of methamphetamine-induced psychosis but not schizophrenia in the Japanese population
20211215 Observational study of gene-disease association, gene-gene interaction, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
19945495 This study demonistrated that the level of metabotropic glutamate receptor 2/3 is elevated in the prefrontal cortex in patient of major depression disorder.
19635471 Our findings suggest that disruption of glutamate receptors like NMDAR1 and mGluR2 at the Shank-postsynaptic platform could contribute to destruction of the postsynaptic density which underlies the synaptic dysfunction and loss in Alzheimer's disease.
19402024 The glutamate receptor metabotropic 2 mutants with increased structural flexibility at this position, which is crucial for pocket closure, were clearly preferred.
19386277 No association is detected between GRM2 and major depressive disorder or bipolar disorder in an allele/genotype-wise or haplotype-wise analysis of Japanese patients.

18853337 The expression of mGluR2, 3 in DA cells provide a mechanism for glutamate to modulate dopamine release in the human brain and this species-specific difference may be critical to understanding rodent models in schizophrenia.
18297054 In post-mortem human brain from untreated schizophrenic subjects, the 2AR is upregulated and the mGluR2 is downregulated, a pattern that could predispose to psychosis
16678921 The objective of this study was to assess the effects of the mGlu2/3 receptor agonist LY404039 (LY) on operant EtOH self-administration during alcohol seeking pavlovian spontaneous recovery, alcohol relapse, and maintenance responding for alcohol.
15837331 Authors have identified and synthesized a brain penetrant propanoic acid as an allosteric potentiator of the metabotropic glutamate receptor 2.

11641422 Ser-148 and Arg-183 may be important for the 3D structure and/or are involved in closure of the domain. Asp-146 is involved in differential binding properties of mGlur2.
