A Single Intrathecal or Intraperitoneal Injection of CB2 Receptor Agonist Attenuates Bone Cancer Pain and Induces a Time-Dependent Modification of GRK2.

“The objective of this study was to explore the potential role of G-protein-coupled receptor kinase 2 (GRK2) in the progression of cannabinoid 2 receptor (CB2) agonist-induced analgesic effects of bone cancer pain.

The results affirmed CB2 receptor agonists might serve as new treatment targets for bone cancer pain.

Moreover, spinal GRK2 was an important regulator of CB2 receptor agonist-analgesia pathway.”
