The present invention is related to a fusion protein comprising a variant of a nucleoprotein antigen from Influenza strain A, B or C, and a variant of a C4bp oligomerization domain for increasing the cellular immunogenicity of the nucleoprotein antigen from Influenza. The invention is also related to nucleic acids, vectors, fusion proteins and immunogenic compositions, for their use as a vaccine or immunotherapy for the prevention and treatment of influenza disease.

Influenza nucleoprotein vaccines

The present application is related to a modified protein comprising a protein having a coiled coil domain and a peptide having the sequence such as shown in SEQ ID NO 1: ZXBBBBZ that is linked to the coiled coil domain wherein: Said modified protein is in particular an antigen or a carrier protein, associated to an antigen. This modified protein has an increased affinity for negatively charged polymers such as nucleic acids or heparin, and shows an increased immunogenicity.

Modified coiled coil type proteins having improved properties

There is provided a fusion protein or a polynucleotide sequence encoding said fusion protein that comprises first and second domains, wherein the first domain of the fusion protein comprises an amino acid sequence having at least 70% sequence identity to the amino acid sequence of SEQ ID NO: 1, or a fragment thereof comprising at least 20 consecutive amino acids thereof; and wherein the second domain of the fusion protein comprises a mycobacterial antigen or an antigenic fragment thereof. Also provided are corresponding therapeutic uses thereof for the protection of primates against mycobacterial infections.

Mycobacterial vaccines

The invention relates to a product which comprises a C4bp domain of a non-mammalian origin, particularly SEQ ID NO:1, SEQ ID NO:23 or SEQ ID NO:37, or a variant thereof, and an antigen. The product is desirably in the form of a fusion protein. The chicken C4bp domain of SEQ ID NO:1 and SEQ ID NO:23 is also described. Antigens include monomeric antigens such as malarial and influenza antigens. The C4bp domain provides for assembly of multimeric complexes of the antigen, or mixtures thereof. The complexes are useful as vaccines.
