Construction of a Eukaryotic Plasmid Encoding Bacillus anthracis Protective Antigen, a Candidate for DNA Vaccine
Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. Objective: To evaluate the use of a DNA immunization strategy for protection against anthrax, a plasmid was constructed. Methods: The partialsequence of protective antigen of Bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...
متن کاملContribution of immunological memory to protective immunity conferred by a Bacillus anthracis protective antigen-based vaccine.
Protective antigen (PA)-based vaccination is an effective countermeasure to anthrax infection. While neutralizing anti-PA antibody titers elicited by this vaccine serve as good correlates for protection against anthrax (S. Reuveny, M. D. White, Y. Y. Adar, Y. Kafri, Z. Altboum, Y. Gozes, D. Kobiler, A. Shafferman, and B. Velan, Infect. Immun. 69:2888-2893, 2001), no data are available on the co...

متن کاملPlant-based vaccine: mice immunized with chloroplast-derived anthrax protective antigen survive anthrax lethal toxin challenge.
The currently available human vaccine for anthrax, derived from the culture supernatant of Bacillus anthracis, contains the protective antigen (PA) and traces of the lethal and edema factors, which may contribute to adverse side effects associated with this vaccine. Therefore, an effective expression system that can provide a clean, safe, and efficacious vaccine is required. In an effort to pro...
متن کاملEffect of nasal immunization with protective antigen of Bacillus anthracis on protective immune response against anthrax toxin.
Anthrax toxin consists of three proteins: protective antigen (PA), lethal factor (LF) and edema factor (EF). PA in combination with LF (lethal toxin) is lethal to mammalian cells and is the major component of human anthrax vaccine. Immunization with PA elicits the production of neutralizing antibodies that form a major component of the protective immunity against anthrax. Recent reports have sh...
