Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.

Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates. The high affinity glutamate transporter EAAC1 was co-transfected with the receptor in order to avoid any influence of glutamate released by the cells in the assay medium. In the experiments carried out by the inventors, Group-III mGluRs were co-transfected with a chimeric G-protein which couples the activation of the receptor to the phospholipase-C (PLC) pathway. Thus receptor activation induces production of inositol phosphate (IP) which in turn induces intracellular Ca2+ release. Receptor activity was then determined by measurement of the IP production or Ca release as already described (Goudet C. et al., PNAS 2004). For intracellular calcium measurements, cells expressing mGluRs were loaded with Ca2+-sensitive fluorescent dye Fluo-4 AM (Invitrogen, Cergy-Pontoise, France) dissolved in Hanks' balanced Salt Solution.Pharmacological Assay: Metabotropic glutamate receptors were transiently transfected in HEK293 cells by electroporation as described elsewhere (Brabet I. et al., 1998) and plated in 96-well microplates.
