Abstract: The invention relates to lipopeptides consisting of a peptide chain comprising a parallel coiled-coil domain, a proline-rich peptide antigen, and a lipid moiety, all covalently linked, which aggregate to synthetic virus-like particles. Proline-rich peptide antigens considered contain negatively and positively charged amino acid, and at least 15% of the amino acids are proline. Such synthetic virus-like particles carrying proline-rich antigens derived from pneumococcal proteins are useful as vaccines against infectious diseases caused by Gram-positive bacteria such as Streptococcus pneumoniae.

Abstract: The invention relates to lipopeptide building blocks consisting of a peptide chain comprising a coiled-coil domain, linked covalently to a lipid moiety comprising long alkyl or alkenyl chains, and optionally linked to an antigen; and to helical lipopeptide bundles and synthetic virus-like particles formed by aggregation. The nanometer size and shape of these bundles and particles, their stability under aqueous physiological conditions, their chemical composition, the possibility to incorporate B- and T-cell epitopes, and their production by chemical synthesis, make them highly suitable as vaccine delivery vehicles.
