Objective
To investigate the effects of retrovirus‐based gene delivery of inhibitory cytokines and cytokine inhibitors into human synovial fibroblasts in the SCID mouse model of rheumatoid arthritis (RA).
Methods
The MFG vector was used for gene delivery of tumor necrosis factor α receptor (TNFαR) p55, viral interleukin‐10 (IL‐10), and murine IL‐10 into RA synovial fibroblasts. The effect on invasion of these cells into human articular cartilage and on perichondrocytic cartilage degradation was examined after 60 days of coimplantation into the SCID mouse.
Results
TNFαR p55 gene transfer showed only a limited effect on inhibition of RA synovial fibroblast invasiveness and cartilage degradation. In contrast, invasion of the RA synovial fibroblasts into the coimplanted cartilage was strongly inhibited by both viral and murine IL‐10. Perichondrocytic cartilage degradation was not affected by either form of IL‐10.
Conclusion
The data show that cytokines can be successfully inserted into the genome of human RA synovial fibroblasts using a retroviral vector delivery system, and that the SCID mouse model of human RA is a valuable tool for examining the effects of gene transfer. In addition, inhibition of more than one cytokine pathway may be required to inhibit both synovial‐ and chondrocyte‐mediated cartilage destruction in RA.
