Abstract : The studies we have conducted under this contract have resulted in the mapping of the continuous antibody (Ab) binding epitopes on the protective Hc domain of BoNT/A with anti-BoNT/A antisera from several outbred species (including human). We have also mapped the continuous Ab and T cell epitopes that are recognized in two mouse strains (BALB/c and SJL) when each of BoNT/A or the Hc is used as an immunogen. Finally we determined the BoNT/A peptides that, when used as immunogens, give immune (Ab and/or T cell) responses that cross-react with Hc and/or with intact toxin. For BALB/c these are peptides 2, 3, 7, 10, 12, 17, 18, 21, 24 and 31; and for SJL they are peptides 4, 5, 6, 7, 8, 10, 15, 24 and 31. These studies have identified the BoNT/A synthetic peptides that represent potentially protective regions for incorporation into a synthetic vaccine.
