It is reported that glutamate induces single-peaked intracellular Ca2+ mobilization in mGluR1α-transfected cells but elicits Ca2- oscillations in m gluR5a-expressing cells, the first evidence that PKC phosphorylation of G-protein-coupled receptors is important in producing oscillations of Ca2 + signalling.

Allodynia and Hyperalgesia in Adjuvant-Induced Arthritic Rats: Time Course of Progression and Efficacy of Analgesics
The present study provided integrated information about the time course of pain and other disease development parameters in the CFA-induced arthritic rats, and clarified acute efficacies of different categories of analgesics for the allodynia and hyperalgesia.

The Metabotropic Glutamate Receptor mGluR5 Induces Calcium Oscillations in Cultured Astrocytes via Protein Kinase C Phosphorylation
It is demonstrated that mGluR5 is capable of inducing [Ca2+]i oscillations in cultured astrocytes and that phosphorylation/dephosphorylation of mGlamorganic glutamate receptor is critical in [Ca1+] i oscillations, analogous to the cloned mGLUR5 expressed in heterologous cell lines.
YM872: a selective, potent and highly water-soluble alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor antagonist.
The evidence for the neuroprotective efficacy of YM872 suggests its therapeutic potential in the treatment of acute stroke in humans and in rats and cats subjected to permanent occlusion of the left middle cerebral artery.
