    摘要: The present invention provides a pharmaceutical composition for the treatment or prevention of an influenza infection. The composition comprises an isolated polypeptide including a sequence of at least 8 contiguous amino acid residues of the fusion initiation region (FIR) of an influenza hemagglutinin 2 protein or a peptide analog of the sequence. The FIR is a segment of the full length hemagglutinin 2 protein which is bounded by an amino-terminal region within the amino-terminal alpha-helix thereof and a carboxy terminus within the carboxy-terminal alpha-helix thereof, with a cysteine loop therebetween. The amino-terminal region of the FIR comprises a portion of the final 10 to 20 amino acid residues of the amino-terminal alpha-helix of the hemagglutinin 2 protein, and includes 3 or 4 hydrophobic amino acid residues, a positively-charged amino acid residue, a negatively-charged amino acid residue, and an aromatic amino acid residue. The carboxy terminus of the FIR is the carboxy terminus of the first peptide sequence of the hemagglutinin 2 protein beyond the amino terminal helix, which exhibits a positive Wimley-White interfacial hydrophobicity.

    摘要: The present invention relates to a method of preventing or inhibiting viral infection of a cell and/or fusion between the envelope of a virus and the membranes of a cell targeted by the virus (thereby preventing delivery of the viral genome into the cell cytoplasm, a step required for. viral infection). The present invention particularly relates to the families of RNA viruses, including the arenaviruses, coronaviruses, filoviruses, orthomyxoviruses, paramyxoviruses, and retroviruses, having Class I membrane fusion proteins as the fusion proteins that mediate this fusion process. The present invention provides for a method of identifying a conserved motif or domain called the fusion initiation region (FIR) in these viruses. The present invention further provides for methods of preventing infection by such viruses, by interfering with their FIR. The present invention further provides for methods of treatment and prophylaxis of diseases induced by such viruses.

    摘要: The instant invention is directed to novel Lassa virus-like particle (VLP) compositions and methods of production thereof. The inventive VLPs comprise, for example, the Lassa virus (LASV) Z matrix protein, glycoproteins (GPs)-I and -2, and nucleoprotein (NP). A novel method for producing these VLPs comprises constructing multicistronic plasmids for the expression of VLP protein components from a single vector. One example is a tricistronic vector containing DNA sequences encoding the LASV Z, GPC and NP proteins. The VLPs provided by the present invention can be used for research, therapeutic and diagnostic purposes.
