Objective:
To investigate the effects of interferon-gamma (IFN-gamma) gene on Tenon's capsule fibroblasts in vitro.
Methods:
Using lipofectAMINE, IFN-gamma gene was transferred to human Tenon's capsule fibroblasts with plasmid pcDNA3IFN-gamma in vitro. Cells treated with plasmid pcDNA3 without IFN-gamma gene were used as the controls. The transfected fibroblasts were screened by G418. The expression of IFN-gamma was determined by RT-PCR, immunohistochemistry and flow cytometry assay. The effects of IFN-gamma on the proliferation of Tenon's capsule fibroblasts were evaluated by flow cytometry and MTT.
Results:
The Tenon's capsule fibroblasts transferred the IFN-gamma gene could express the IFN-gamma RNA and protein transiently. The proliferation of the fibroblasts transferred the IFN-gamma gene was inhibited.
Conclusion:
The proliferation of the Tenon's capsule fibroblasts in vitro can be inhibited by transferred IFN-gamma gene.
