摘要:
For the efficient surface presentation and release of virulence factors especially pathogenic Gram-negative bacteria have developed several distinct secretion mechanisms. An increasing number of pathogens in various species employs a mechanism denoted the 'autotransporter' pathway. This pathway is characterised by an outer membrane translocator module representing the C-terminal domain of the transported protein itself All intriguing potential application of such systems involves the transport and surface expression of recombinant proteins or peptides, like e.g. the presentation of antigens for the generation of live oral vectors as vaccine carriers. Here we report on the incorporation of heterologous (poly-) peptides in permissive sites of the translocator module of the adhesin-involved-in-diffuse-adherence (AIDA) autotransporter system. We demonstrate the presentation of the B subunit of the heat labile enterotoxin of Escherichia coli (LTB) as well as of functional T-cell epitopes of Yersinia enterocolitica heal-shock protein 60 (Y-hsp60) on the surface of E. coli.
