Abstract
The invention relates to a modified factor H binding protein (fHbp), comprising fHbp, or a variant thereof, modified with the addition of at least one exogenous peptide loop; and associated nucleic acid, compositions, and uses. The invention further relates to treatment or prevention of a pathogenic infection or colonisation of a subject using the modified factor H binding protein (fHbp).
Claims6
A modified factor H binding protein (fHbp), comprising wild-type fHbp or the wild-type gonococcal orthologue of fHbp (Ghfp) having at least 95% identity with any of the sequences of SEQ ID NOs:
- 1-13, which is further modified with the addition of at least one PorA loop comprising a sequence according to any of SEQ ID NOs:
- 45 to 79, or variant thereof having no more than 5 amino acid additions, deletions or substitutions,
- wherein the PorA loop is between 8 and 20 amino acids in length and wherein the PorA loop is inserted at an amino acid position that is corresponding to any one of the amino acid residue numbers 49-54, 83-88, 114-124, 199-206, 227-233, and 240-246 of SEQ ID NO:
- 1, or equivalent residues in any of SEQ ID NOs:
- 2 to 13.
