ABSTRACT
<p><b>OBJECTIVE</b>To test the infeciton efficiency of recombinant adenoviral vector carrying HBsAg-HSP70 chimeric gene and to abserve its biological characteristics.</p><p><b>METHODS</b>Peripheral blood mononuclear cells (PBMC) were separated from healthy blood donor and they were infected by Ad-HSP70-HBsAg on the first day of isolation. DCs were induced in medium with cytokines IL-4, GM-CSF and TNF-alpha in vitro. The biological characteristics of DC induced were analyzed by inverted fluorecent microscope, RT-PCR, flow cytometer (FACS), and mixed lymphocyte reaction (MLR).</p><p><b>RESULTS</b>The traced gene-GFP were abserved in DCs by inverted fluorecent microscope and HSP70-HBsAg gene mRNA expression was detected by RT-PCR after the Ad-HSP70-HBsAg infection. FACS analysis shown that the expression of CD1a, CD80, CD86 and HLA-DR on surfece of two groups of DCs were similar. MLR showed that there are not a statitic difference of stimulated index (SI) between two groups.</p><p><b>CONCLUSION</b>Results indicated that Ad-HSP70-HBsAg can effectively infected DCs without affecting its biological characteristics.</p>
