Abstract: The present invention relates to a fusion protein, a nucleotide sequence encoding such a fusion protein, the use thereof as an adjuvant or vaccine. The fustin protein comprises a bacterial exotoxin and a single chain antibody fragment (scFv) that specifically binds to a surface marker on dendritic cells. The fusion protein is advantageously administered intranasally, orally or intrapulmonarily.

Abstract: The present invention provides improved methods and compositions for treating and preventing autoimmune and allergic diseases. More specifically, the invention relates to new immunomodulating complexes that are fusion proteins comprising a mutant subunit of the A1-subunit of the cholera toxin (CTA1), a peptide capable of binding to a specific cellular receptor, and one or more epitopes associated with an autoimmune or allergic disease. In the mutant CTA1 subunit, the amino acids corresponding to the amino acid 7, arginine, and amino acid 187, cysteine, in the native CTA1 have been replaced.

Abstract: The present invention provides improved methods and compositions for treating and preventing autoimmune and allergic diseases. More specifically the invention relates to new immuno-modulating complexes which are fusion proteins comprising mutant subunits of bacterial endotoxins, a peptide capable of binding to a specific cellular receptor, and one or more epitopes associated with an autoimmune or allergic disease.

Abstract: The invention relates to an immunogenic complex comprising at a least one glycoside and at least one lipid, integrated into an iscom complex or matrix, and at least one antigen which antigen is integrated into the iscom complex or coupled on to or mixed with the iscom complex or iscom matrix complex, characterised in that it also comprises at least one enzyme. It also relates to such a complex further comprising at least one peptide which specifically binds to a receptor expressed on a cell capable of antigen presentation, which cell expresses MHC Class I or Class II and to compositions comprising the complexes.

Abstract: A DNA-sequence comprising a first sequence coding for a native or mutant subunit of a bacterial toxin that confers enzymatic ADP-ribosylating activity, and a second sequence coding for a peptide such that the resulting fusion protein is in possession of water solubility and capability of targeting the fusion protein to a specific cell receptor different from receptors binding to the native toxin, thereby mediating intracellular uptake of at least said subunit;fusion proteins coded for by such DNA-sequence;compositions for use in improving immune functions; andrecombinant expression vectors and transformed bacterial cells containing such DNA-sequence.
