Intrathecal Injection of Metabotropic Glutamate Receptor Subtype 3 and 5 Agonist/Antagonist Attenuates Bone Cancer Pain by Inhibition of Spinal Astrocyte Activation in a Mouse Model

Abstract

Spinal mGluR3 activation or mGluR5 inhibition reduced bone cancer pain. Inhibition of spinal astrocyte activation may contribute to the analgesic effects. These findings may lead to novel strategies for the treatment of bone cancer pain.
