Abstract |
DNA vaccines have been demonstrated to be effective in inducing protective cell-mediated immune responses in animal models of infectious disease. In order to investigate this approach for potential use as a vaccine for tuberculosis, DNA constructs encoding Mycobacterium tuberculosis antigen 85A (Ag85A) were prepared. Expression of Ag85A in mammalian cells was demonstrated by transient transfection of cells in vitro. Intramuscular injection of Ag85A DNA vaccines resulted in the generation of anti-Ag85A antibodies and robust cell-mediated immune responses, as measured by lymphoproliferation of spleen cells in vitro upon specific antigen restimulation, leading to protection in animal challenge models. Therefore, the technique of DNA vaccination is effective in inducing relevant immune responses for protection against tuberculosis and may be used to identify the protective antigens of M. tuberculosis.
