  • Patent number: 11926648
    Abstract: A flavivirus Envelope Dimer Epitope (EDE) and isolated neutralizing antibody or antigen binding fragment thereof directed against the EDE for use in vaccinating an individual against one or more flaviviruses wherein the EDE is a stabilized recombinant flavivirus are provided. The dimer is: covalently stabilized with at least one disulphide inter-chain bond or one sulfhydryl-reactive crosslinker between the two sE monomers, and/or by being formed as a single polypeptide chain, and/or by linking the two sE monomers through modified sugar, and/or non-covalently stabilized by substituting at least one amino acid residue in the amino acid sequence of at least one sE monomer with at least one bulky side chain amino acid, at the dimer interface or in domain 1 (D1)/domain 3 (D3) linker of each monomer. The dimer is a homodimer or heterodimer of native and/or mutant envelope polypeptides, from DENV-1, DENV-2, DENV-3, DENV-4, Zika and/or other flavivirus.

  • Publication number: 20050214311
    Abstract: The invention relates to induction of immune responses against target antigens using Fas ligand as an adjuvant. Melanoma cell lines transfected with FasL are shown to be rejected more efficiently than untransfected cells, and rejection is shown to be antibody-mediated. The invention provides immune complexes comprising target antigens and Fas ligand, pharmaceutical compositions comprising such immune complexes, and methods for generating immune responses, as well as methods for identifying cell-specific antigens, particularly tumour specific antigens, using cells expressing FasL.

  • Publication number: 20040146520
    Abstract: The invention provides immunocomplex comprising MHC molecules or functional fragments thereof which are modified so as to prevent binding to co-receptors e.g. CD8 or CD4. The inventors have determined that inability of the MHC complex to bind co-receptor leads to death of the T-cells without delivery of an activation/proliferation signal. By associating the immunocomplex with a specific peptide antigen it is possible to selectively suppress the immune system of a host, i.e. to help prevent tissue rejection or treat autoimmune diseases. For a more universal suppression of the immune system, it is possible to administer the modified MHC complex or fragment/component thereof in the absence of peptide antigen. For example, modified &bgr;M complex can be administered.
