摘要：
The invention relates to the field of immunology and vaccine development, in particular to the development of vaccines based on native antigen oligomers. Provided is an immunogenic composition in particulate form, comprising oligomers of a surface exposed polypeptide of pathogenic origin or tumor origin, or antigenic part thereof, said oligomers being bound non-covalently to a particulate carrier, and a pharmaceutically acceptable diluent or excipient. Also provided is a recombinant polypeptide comprising (A) an N- or C-terminal antigenic domain, comprising at least one surface exposed polypeptide of pathogenic or tumor origin, or antigenic part thereof, the antigenic domain being fused to (B) an oligomerization domain (OMD), said oligomerization domain being fused via (C) a linker domain to (D) a peptidoglycan binding domain (PBD) consisting of a single copy of a LysM domain capable of mediating the non-covalent attachment of the polypeptide to a non-viable bacterium-like particle (BLP) obtained from a Gram-positive bacterium.
