| Outline of Final Research Achievements |
We confirmed the inhibitory effects of sunitinib, a inhibitor of vascular endothelial growth factor receptor tyrosine kinase, on murine arthritis model.
Sunitinib at a concentration of 0, 30 or 60mg/kg/day was intraperitoneally administrated to mice with collagen-induced arthritis. We compared the changes in arthritis score over time, pathological score, microvascular density in synovial membrane between the vehicle and treatment groups.
In the sunitinib-treated groups, the arthritis score decreased in a dose-dependent manner in comparison with that in the vehicle group. Futhermore, improvement in the pathological score, and a decrease in the synovial microvascular density were also observed in the sunitinib-treated groups.
