Dimeric and trimeric proteins based on the fimh, csga, and papg adhesins of uropathogenic escherichia coli

Abstract

The present invention is based on the fusion of FimH, CsgA and PapG adhesins (type 1 Fimbriae, curli and P, respectively) to generate biomolecules that can be used as vaccines against UTIs. Briefly, the invention is based on the design of a fusion template gene fimH-csgA-papG-fimH-csgA and defined as fcpfc to generate the different combinations of monomeric [FimH, CsgA and PapG], dimeric [FimH-CsgA (FC), CsgA-PapG (CP) and PapG-FimH (PF)] and trimeric (FimH-PapG-CsgA (FCP), PapG-CsgA-FimH (PCF) and CsgA-FimH-PapG (CFP)] proteins. Bioactivity was determined by the antibodies present in UP sera and urine, the quantification in the release of cytokines and adhesion inhibition assays.
