摘要： A bioconjugate of an E. coli glucosylated O4 antigen polysaccharide covalently linked to a carrier protein and compositions thereof are provided. Also provided are recombinant host cells for producing the bioconjugate, and methods of producing the bioconjugate using the recombinant host cells. The recombinant host cells contain a nucleic acid encoding a glucosyl transferase capable of modifying the E. coli O4 antigen with glucose branching to produce the glucosylated O4 antigen polysaccharide. Bioconjugates of an E. coli glucosylated O4 antigen polysaccharide described herein can be used alone or in combination with one or more additional E. coli O-antigen polysaccharides to induce antibodies against an E. coli glucosylated antigen, and to vaccinate a subject against extra-intestinal pathogenic E. coli (ExPEC).

摘要： This invention generally relates to cationic oil-in-water emulsions that contain high concentrations of cationic lipids and have a defined oil:lipid ratio. The cationic lipid can interact with the negatively charged molecule thereby anchoring the molecule to the emulsion particles. The cationic emulsions described herein are useful for delivering negatively charged molecules, such as nucleic acid molecules to cells, and for formulating nucleic acid-based vaccines.

摘要： This invention generally relates to cationic oil-in-water emulsions that can be used to deliver negatively charged molecules, such as an RNA molecule. The emulsion particles comprise an oil core and a cationic lipid. The cationic lipid can interact with the negatively charged molecule thereby anchoring the molecule to the emulsion particles. The cationic emulsions described herein are particularly suitable for delivering nucleic acid molecules (such as an RNA molecule encoding an antigen) to cells and formulating nucleic acid-based vaccines.
