Gene therapy in rheumatoid arthritis: how to target joint destruction?
HealthData.Gov
The field of gene therapy for bone and joint disorders has grown considerably over the last two and a half years. Investigators have shown that ex vivo or in vivo gene transfer is highly effective in blocking arthritis…
