ABSTRACT
<p><b>OBJECTIVE</b>To construct a DNA vaccine as a prophylactic model to prevent condyloma acuminatum and detect its immunogenicity in mice.</p><p><b>METHODS</b>The major capsid protein (L1) gene of human papillomavirus (HPV) 6b was inserted into an eukaryotic expression plasmid (pcDNA3.1). The recombinant plasmid was transfected into COS-7 cells. Western blot were performed to detect whether L1 protein can be expressed in eukaryotic cells. Eighteen female BALB/c mice were tested for immunogenicity study.</p><p><b>RESULTS</b>The recombinant plasmid (pcDNA3.1-HPV6bL1) was verified as HPV6b L1 gene by sequencing. Western blot showed specific strip. Anti-L1 protein antibodies could be detected in the mice's sera inoculated with pcDNA3.1-HPV6bL1. Similarly, IL-4, IL-2, and IFN-gamma were increased in the same mice.</p><p><b>CONCLUSION</b>HPV6b L1 recombinant plasmid was constructed successfully which had immunogenicity for BALB/c mice. It provided experimental evidence for the research of DNA vaccine of condyloma acuminata.</p>
