Abstract

Plasmid DNA expression vectors encoding Mycobacterium tuberculosis antigen 85 (Ag85) were tested as vaccines in preclinical animal models. Expression of secreted and nonsecreted forms of Ag85 was observed after transient transfection of cells in vitro. In mice, both types of Ag85 DNA constructs induced strong humoral and cell-mediated immune responses, as measured by ELISA of sera and recall responses of spleen cells restimulated in vitro, respectively, Therefore, DNA vaccination is an effective means of expressing mycobacterial proteins in eukaryotic cells leading to the induction of potent immune responses.
