| Popis: | IL-10 is a potent anti-inflammatory cytokine that has received growing attention for its therapeutic potential. We examined the efficiency of adenoviral-mediated gene transfer of IL-10 on the incidence and severity of murine collagen-induced arthritis (CIA). Male DBA1 mice immunized with collagen II were treated by systemic administration of 109 plaque-forming units of replication-defective adenoviral vector expressing viral IL-10 (vIL-10) on day 30, when clinical symptoms of arthritis start. The transgene was shown to inhibit the onset of CIA, to decrease severity, and profoundly suppress the overall joint histopathology of the experimental arthritis. Significant IL-10 concentrations were obtained in the serum of injected animals for 7 days. Inhibition of arthritis was enhanced by administration of increasing doses of adenovirus-vIL-10. In addition, the local immunosuppressive effect of gene-delivered vIL-10 could be neutralized by a monoclonal anti-vIL-10 Ab. The CIA symptoms in the group treated with the same construct expressing inactive vIL-10 (vIL-10 mut) were similar to those in untreated animals. Our data indicate that a single systemic administration of an adenoviral vector encoding vIL-10 may be a good candidate to suppress arthritis. |
