The accessory colonization factor A (ACFA) of Vibrio alginolyticus plays an important role in the efficient colonization of the bacterium and is potential candidates for vaccine development. In present study, the acfA gene was cloned, expressed and purified. Western blot analysis revealed protein recognition with the native ACFA in different V. alginolyticus strains. To analyze the immunogenicity...
Gene-based hepatitis B virus (HBV) vaccines have been proposed as a novel approach to improve the immunogenicity toward non-responders and to allow for protection against potential viral escape mutants. Furthermore, there is significant interest in using DNA or viral vector vaccines to serve as therapeutic agents to treat chronic HBV infections that are resistant to existing drug therapies. However,...
Developing an effective HIV-1 vaccine will require strategies to enhance antigen presentation to the immune system. In a previous study we demonstrated a marked increase in immunogenicity of the highly glycosylated HIV-1 gp120 protein following enzymatic addition of α-gal epitopes to the carbohydrate chains. In the present study we determined whether gp120 αgal can also serve as an effective...
Yersinia Pestis outer proteins, plasminogen activator protease and Yop secretion protein F are necessary for the full virulence of Yesinia pestis and have been proposed as potential protective antigens for vaccines against plague. In the current study, we used DNA immunization as a tool to study the relative protective immunity of these proteins with a standardized intranasal challenge system in mice...
