title: [Specific cellular and humoral immune responses induced by intramuscular injection of DNA vaccine containing HBV HBsAg gene in mice].
abstract: To know the influences on the function of cellular and humoral immunity in mice by DNA vaccine containing HBV HBsAg gene, the DNA vaccine, pcDNA3-HBsAg, in which the HBsAg gene sequences of HBV were inserted into downstream of CMV promoter in pcDNA3, were injected intramuscularly into Balb/C mice. The results were that the serum anti-HBsIgG was detected in all of the pcDNA3-HBsAg immunized mice, but none in control mice; serum levels of Th1 cytokines, interleukine 2, and interferon gamma, were significantly higher in pcDNA3-HBsAg immunized mice than these in controls. It is indicated that the good responses of cellular and humoral immunity can be induced by injection of pcDNA3-HBsAg in Balb/C mice.
