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

The present invention relates to conjugates of oligosaccharides of formula 1, wherein R is a linker to a carrier protein and optionally comprises up to three further saccharides, 5 and which are useful for vaccination, methods of synthesis of such conjugates, antibodies against this antigen, hybridoma producing monoclonal antibodies against this antigen, assays using these antibodies for the detection ofspores and kits comprising these antibodies, and a vaccine for the prevention ofinfection comprising the conjugates of oligosaccharides of formula 1. Monoclonal antibodies 10 according to the invention selectively bind to, but not to related bacteria such asand other bacteria of this group such as. 

The present invention relates to methods for synthesizing conformationally constrained peptides and cyclic peptidomimetics obtainable by these methods which are conformationally constrained due an internal cross-link. This cross-link is formed between the side chain of an amino acid residue or analog and a (2S, 4S)4-functionalized proline residue. The invention further relates to the use of (2S, 4S)-4-functionalized proline residues as building units in the synthesis of such peptidomimetics and to the use thereof as antigens, alone or in combination with suitable immunopotentiating delivery systems, for example immunopotentiating reconstituted influenza virosomes to elicit an immune response in a mammal. Moreover, the invention also relates to pharmaceutical compositions containing the same.

Method for synthesizing conformationally constrained peptides, peptidomimetics and the use thereof as synthetic vaccines

The invention presents vaccine formulations comprising highly antigenic epitopes identified within the semi-conserved loop-I of domain III that are capable of eliciting parasite growth inhibitory antibodies. The cyclized or linear peptides can be applied by known adjuvants or be encapsulated by or attached onto the surface of liposomes or virosomes (IRIVs) which serve as human compatible antigen delivery systems. Both cyclized and linear versions of the peptide antigens are surprisingly effective in eliciting immune responses that are cross-reactive with parasite-expressed AMA-1.
