Tumor necrosis factor a plays primary role in the pathogenesis of inflammatory diseases. TNFot is essential for antigen-specific IgE production and for the induction of Th2-type cytokines. The lack of TNF alpha inhibited the development of allergic rhinitis. In this study, the chimeric gene of soluble TNF receptor and IgGFc fragment (sTNFR-IgGFc) was cloned into the EBV-based plasmid pGEG. When the plasmid pGEG-sTNFR-IgGFc was transferred to endothelium cell, a considerable expression of the sTNFR-IgGFc fusion protein was detected. Moreover, the expression product in the supernatant, could antagonize the cytolytic activity of TNFot on L929 cells. Then the plasmid was delivered into nasal mucosa of allergic rhinitis mice to determine its effect on this animal model. Results showed that symptoms in treated group were improved. Pathological examination showed the numbers of eosinophil, mast cell and IL-5(+) cells in treated groups were reduced compared with placebo group. These data showed that pGEG-sTNFR-IgGFc expression plasmid is potential for the treatment of allergic rhinitis, and suggest that the antagonist of TNFa may provide a new approach for the treatment of allergic rhinitis.
