Generation and Characterization of Human Monoclonal Antibodies Targeting Anthrax Protective Antigen following Vaccination with a Recombinant Protective Antigen Vaccine.
The anthrax protective antigen (PA) is the central component of the three-part anthrax toxin, and it is the primary immunogenic component in the approved AVA anthrax vaccine and the "next-generation" recombinant PA (rPA) anthrax vaccines. Animal models have indicated that PA-specific antibodies (AB) are sufficient to protect against infection with Bacillus anthracis. In this study, we investiga...
متن کاملHuman anti-anthrax protective antigen neutralizing monoclonal antibodies derived from donors vaccinated with anthrax vaccine adsorbed
BACKGROUND: Potent anthrax toxin neutralizing human monoclonal antibodies were generated from peripheral blood lymphocytes obtained from Anthrax Vaccine Adsorbed (AVA) immune donors. The anti-anthrax toxin human monoclonal antibodies were evaluated for neutralization of anthrax lethal toxin in vivo in the Fisher 344 rat bolus toxin challenge model. METHODS: Human peripheral blood lymphocytes fr...
متن کاملAntigen-specific CD4+ T cells recognize epitopes of protective antigen following vaccination with an anthrax vaccine.
Detection of antigen-specific CD4+ T cells is facilitated by the use of fluorescently labeled soluble peptide-major histocompatibility complex (MHC) multimers which mirror the antigen specificity of T-cell receptor recognition. We have used soluble peptide-MHC class II tetramers containing peptides from the protective antigen (PA) of Bacillus anthracis to detect circulating T cells in periphera...
متن کاملGeneration and characterization of monoclonal antibodies to protective antigen of Bacillus anthracis.
Monoclonal antibodies (MoAbs) were generated following immunization of BALB/c mice with protective antigen (PA) of B. anthracis. Five clones reactive to this protein were stabilized and preserved. These MoAbs could detect nanogram levels of PA when tested in ELISA. In Western blotting, they reacted with all PA preparations tested and no cross-reactivity was observed with lethal factor, edema fa...
متن کاملProduction and Characterization of Monoclonal Antibodies Recognizing a Common 57-kDa Antigen of Leishmania Species
Background: The therapy of leishmania infection is difficult and each year 1.5 million new cases of cutaneous leishmaniasis and 500,000 new cases of visceral leishmaniasis are estimated, therefore, there is a need for an effective vaccine. Monoclonal antibody (mAb) is one of the suitable methods for isolation and purification of leishmania antigens. In this report, we produced several mAb aga...
