    摘要: A modified polypeptide corresponding to an envelope glycoprotein of a primate lentivirus is described. The polypeptide has been modified from the wild-type structure so that it has cysteine amino acid residues introduced to create disulfide bonds, a cavity is filled with hydrophobic amino acids, a Proresidue is introduced at a defined turn structure of the protein, or the hydrophobicity is increased across the interface between different domains, while retaining the overall 3-dimensional structure of a discontinuous conserved epitope of the wild-type protein. Preferably, the polypeptide has more than one of those characteristics. Preferably, the primate lentivirus is HIV, and the protein is HIV-1 gp120.

    摘要: A modified polypeptide corresponding to an envelope glycoprotein of a primate lentivirus is described. The polypeptide has been modified from the wild-type structure so that it has at least two of the glycosylation sites proximal to the CD4 binding site or chemokine receptor site altered so that the alteration prevents glycosylation at that site or where glycosylation sites distal to these sites have been derivatized with a molecular adjuvant, while retaining the overall 3-dimensional structure of a discontinuous conserved epitope of the wild-type protein. Preferably, the polypeptide has both changes. Preferably, the primate lentivirus is HIV, and the protein is HIV-1 gp 120.

    摘要: An immunogenic proteoliposome containing a transmembrane protein or oligomeric complexes containing such proteins, including viral envelope glycoproteins, in a lipid membrane around an elliptoid or spherical shape. The shape preferably also contains an attractant such as streptavidin or avidin and the lipid membrane contains a moiety that binds to the attractant such as biotin. The immunogenic transmembrane protein is bound to a ligand which is anchored in the shape. Methods for making the immunogenic proteoliposomes are provided uses of the proteoliposome are described, including their use as immunogens to elicit immune reaction, and their use in screening assays, including their use as antigens to screen antibody libraries, as well as for drug screening and the identification of ligands.
