Title

A study on the immune response induced by a DNA vaccine encoding Mtb32C-HBHA antigen of Mycobacterium tuberculosis

Pages

  1119-1124

Abstract

 Objective(s): Tuberculosis (TB) has still remained a global health issue. One third of the world's population is infected with tuberculosis and the current BCG vaccine has low efficiency; hence, it is necessary to develop a new vaccine against TB. The aim of the current study was to evaluate the efficiency of a novel DNA vaccine encoding Mtb32C-HBHA antigen in inducing specific immune responses against Mycobacterium tuberculosis. Materials and Methods: A DNA Plasmid vaccine expressing Mtb32C-HBHA fusion protein was constructed and its ability in protein expression was examined by RT-PCR and Western blot methods. Female BALB/c mice were vaccinated with 100 μ g of purified recombinant vector in an attempt to assess its immunogenicity and protective efficacy. Further, the cytokines, IFN-γ , IL-12, IL-4, IL-10, and TGF-β were assessed. Results: The levels of all the studied cytokines were significantly increased (P<0. 05) compared with the control group. IFN-γ production in the group receiving DNA vaccine plus BCG was increased compared with those receiving only DNA vaccine or BCG (P<0. 001). Conclusion: The immunogenicity of the new chimeric DNA vaccine was confirmed alone and in combination with BCG. Based on the results of the current study, the constructed DNA vaccine induced the expression of Mtb32C-HBHA fusion protein efficiently in vitro. Furthermore, high levels of the specific cytokines were induced in mice. By using this DNA vaccine as a booster after BCG, higher amounts of IFN-γ will be produced.
