Host immunity to Bacillus anthracis lethal factor and other immunogens: implications for vaccine design.

Abstract:

:Infections of humans with Bacillus anthracis are an issue with respect to the biothreat both to civilians and military personnel, infections of individuals by infected livestock in endemic regions and, recently, infections of intravenous drug users injecting anthrax-contaminated heroin. Existing vaccination regimens are reliant on protective antigen neutralization induced by repeated boosts with the AVA or AVP vaccines. However, there is ongoing interest in updated approaches in light of the intensive booster regime and extent of reactogenicity inherent in the current protocols. Several other immunogens from the B. anthracis proteome have been characterized in recent years, including lethal factor. Lethal factor induces strong CD4 T-cell immunity and encompasses immunodominant epitopes of relevance across diverse HLA polymorphisms. Taken together, recent studies emphasize the potential benefits of vaccines able to confer synergistic immunity to protective antigen and to other immunogens, targeting both B-cell and T-cell repertoires.

  • The baboon model of pertussis: effective use and lessons for pertussis vaccines.

    abstract::The USA is experiencing a pertussis resurgence that resulted in a 60-year high of 48,000 cases in 2012. Our ability to counteract this resurgence is hampered by the fact that pertussis pathogenesis and immunity to pertussis infection are not well studied. Studies in humans are difficult due to the low frequency of per...
