Methods: The persistent stimulation of BC-3 was conducted by several cytokines known to be produced by HIV-1-infected T cells and important in growth and proliferation of Kaposi's sarcoma(KS)cells in vitro, such as the interferon-γ (IFN-γ) , tlie hepatocyte growth factor/scatter factor (HGF / SF) , the Oncostain M(OSM) , and the tumor necrosis factor-α (TNF-α)which is not produced by HIV-1-infected T cells. Treated and untreated BC-3 cells were collected at the 3rd and 7th day of persistent stimulation, respectively. Immuno-histochemical (IHC) staining, Northern blot, quantitative PCR (real- time PCR ) and electron microscopy (EM) were carried out to detect the expression of immunogenic protein ORF59, messenger RNA (mRNA) of minor capsid protein ORF26, and the presence of viral particles of HHV-8 from treated and untreated BC-3 cells. Results: It showed that IFN-γ, HGF/SF, OSM, and TNF-α were found to induce an increase in mRNA expression of ORF26 when added individually to BC-3 cells. Particularly, ORF26 expression stimulated with IFN-γ and TNF-α respectively, increased 6. 1 and 2. 5-fold(from real-time PCR results)at the 7th day when compared with untreated BC-3 cells. Meanwhile, about 20% of IFN-γ stimulated BC-3 cells expressed ORF59 at the 7th day as compared with 1. 5% of untreated BC-3 cells when IHC staining was employed. In addition, viral particles of HHV-8 were readily identified in BC-3 cells stimulated with IFN-γ at the 7th day with EM analysis. Conclusion;TNF-α and recombinant cytokines being similar to those produced by HIV- 1 infected T Cells could really induce HHV- 8 lytic cycle replication in BC-3 cells, another cell line of PEL.展开更多
