Identification Of B-Cell Epitopes On Domain 4 Of Anthrax Protective Antigen, Cassandra D. Kelly-Cirino
Identification Of B-Cell Epitopes On Domain 4 Of Anthrax Protective Antigen, Cassandra D. Kelly-Cirino
Legacy Theses & Dissertations (2009 - 2024)
Protective Antigen (PA) is the receptor binding subunit common to both Lethal (LT) and Edema (ET) toxins, which contribute to the mortality associated with Bacillus anthracis infection. While recombinant PA (rPA) is likely to be an important constituent of second generation anthrax vaccines, evaluating the effectiveness of candidate vaccines is currently difficult, because the specific B cell epitopes involved in toxin neutralization have not been completely defined. The only well characterized antibody, 14B7, has been shown to disrupt the association of PA with the anthrax toxin receptors (ATR) by binding to domain 4 of PA. I hypothesized that other domain …
