Abstract: A fusion polypeptide, comprising an inclusion body tag fused to at least one polypeptide of interest, is provided. The inclusion body tag comprises an inclusion body forming (IBF) amino acid sequence selected from X14X15AX17X18X19GLTVA GMLG and sequences having at least 71% identity thereto. Also provided are inclusion bodies comprising the fusion polypeptide, as well as nucleic acids, expression vectors, host cells and methods for its production.
Abstract: The present invention concerns Gram-negative bacterial cells or Outer Membrane Vesicles (OMVs) which display on their outer surface an autotransporter (AT) fusion protein covalently coupled via an isopeptide bond to a heterologous molecule. These bacterial cells and OMVs are suitable for use in vaccines or targeted drug delivery of antigens or therapeutic agents to specific cells or tissues.

Abstract: There is provided a fusion protein suitable for secretion of more than one polypeptide(s) of interest (POI) comprising a signal peptide, a POI, a passenger domain comprising a beta stem domain from an autotransporter protein, and a translocator domain from an autotransporter protein, wherein the beta stem-forming sequence of the passenger domain is essentially intact and the POI(s) is/are fused to the beta stem domain.
