BoNTA Hcbtre immunogens induce antibodies that recognize epitopes distinct from these induced by BoNTA toxoid. Day sera from a subset of rabbits included in Figure had been tested for the presence of antibodies particular for BoNTA Hc or BoNTA toxoid by ELISA. a: serum antiBoNTA toxoid IgG titers significantly higher than those induced by all other groups. There have been no other considerable differences among groups.ponegcular immunization with BoNTA toxoid + alum induced significantly elevated serum antiBoNTA toxoid IgG titers (:,) that have been considerably higher than all other vaccine groups tested. In agreement with published literature, our outcomes demonstrate that the antigenicity of BoNTA toxoid is drastically unique than recombint forms of immunogens considering that immunization with BoNTA toxoid induced antibodies able to recognize toxoid but not BoNTA Hcbtre or Hc.AdF enhances PubMed ID:http://jpet.aspetjournals.org/content/139/1/60 btrefoil immunogenicity in Dutch Belted rabbits just after intrasal immunization with cholera toxin or the mast cell activator adjuvant CTo ascertain if the superior immunogenicity of HcbtreAdF and also the adjuvant activity of C may be confirmed in a second rabbit strain, we repeated the intrasal immunization protocol working with BoNTA Hcbtre or HcbtreAdF CT or C in Dutch Belted rabbits. Four rabbits per group had been immunized on days,, and using the similar molar doses of Hcbtre ( mg) or HcbtreAdF ( mg) alone or combined with CT ( mg) or C ( mg). Sera collected on days, and have been evaluated for the presence of btrefoil certain IgG antibodies by ELISA (Figure ). On day, the only groups with drastically increased serum antiBoNTA Hcbtre IgG titers were rabbits sally immunized with HcbtreAdF + CT (:,) or HcbtreAdF + C (:,). These results demonstrate that the addition of AdF as a mucosal targeting ligand when combined with adjuvant (CT or C) enhanced the immunogenicity on the Hcbtre immunogen and enhanced the induction of serum antiHcbtre IgG responses immediately after sal vaccition. The serum antiHcbtre IgG titers induced by sal immunization with HcbtreAdF + C have been drastically greater than titers induced by sal immunization with HcbtreAdF alone (p) demonstrating the mucosal adjuvant activity of C (Figure ).
