摘要：
In this study, we examined the involvement of chemokine monocyte chemoattractant protein-1 (MCP-1) in the spinal cord of a rat model of cancer-induced bone pain (CIBP). In this model. CIBP was established by an intramedullary injection of Walker 256 cells into the tibia of rats. We observed a significant increase in expression levels of MCP-1 and its receptor CCR2 in the spinal cord of CIBP rats. Furthermore, the intrathecal administration of an anti-MCP-1 neutralizing antibody attenuated the mechanical allodynia established in CIBP rats. Likewise, an intrathecal injection of exogenous recombinant MCP-1 induced a striking mechanical allodynia in naive rats. These results suggest that increases in spinal MCP-1 and CCR2 expression are involved in the development of mechanical allodynia associated with bone cancer rats. (c) 2012 Elsevier Ireland Ltd.
