摘要:
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.

The present invention relates to a truncated form of the secretory aspartyl proteinase 2 (Sap2), as well as to nucleic acid molecules encoding same. This truncated Sap2 polypeptide (tSap2) is surprisingly stable and devoid of enzymatic activity but retains full immunogenicity upon intravaginal administration and confers full protection against intravaginal challenge by the Candida fungus. The present invention further relates to compositions comprising tSap2 and to the use of tSap2 in the preparation of such compositions.
摘要:
The invention relates to novel adjuvant systems that generate efficient immune responses against antigens of choice. The novel adjuvant systems of the present invention are based on virosomes. Thus the invention is directed to pharmaceutical compositions comprising virosomes, at least one antigenic molecule, and a carrier vehicle, methods for preparing such compositions and uses thereof.

The present invention relates to methods and compositions for the elicitation of an immune response against amyloid beta-peptides, in particular by the combinatory use of virosomes as adjuvants and a synthetic amyloid beta-peptide antigen.

摘要:
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.
