Humoral and Cellular Immunogenecity of DNA Vaccine of HIV-2 Chimeric Gene gag-gp105 in BALB/c
Abstract: The recombinant expression plasmid of pVAX1gag-gp105 was constructed and transfected into BHK21 cells by lipofectamine, the expressed product was detected by indirect immunofluore scence. After the mice were immunized with pVAX1gag-gp105 and control plasmid, the number of CD4＋and CD8＋ subgroups of spleen T lymphocyte, the specific killing activities of spleen CTL and the titers of serum antibodies of the immunized mice were detected. Compared with vaccinated control groups, pVAX1gag-gp105 vaccinated group had significant differences in the titers of the serum antibodies (P0.01), the numbers of spleen CD4+ and CD8+ T cells (P0.05) and the specific killing activities of spleen CTL (P0.01). These results manifested that the DNA vaccine based on HIV-2 chimeric gene gag-gp105 possessed good humoral and cellular immunogenecity in BALB/c mice.
