CF-multiHP

CF – Chimeric fusion protein, which retains the central, most antigenic segment of H. pylori (hypervariable region) flagellin FlaA, while replacing the N- and C-terminal segment by the FliC flagellin from E. coli, which is responsible for the activation of TLR5 (176 AA from the N-terminal and 99 AA from the C-terminal). Thus, combining the right parts of flagellin of E. coli with that of H. pylori enables activation of innate immunity - a characteristic that flagellin of H. pylori alone does not posess - while presenting the antigen of H. pylori for antibody production..

We also designed synthetic multiepitope, comprising the H. pylori urease B epitope, a vacuolating cytotoxin A (Vac) epitope and an adhesin A (HpaA) epitope. B-cell epitopes were designed using available 3D models or structures, which enabled more accurate prediction. Multiepitope is a synthetic gene orderd from GeneArt.
