Abstract: Described are binding molecules, e.g., human monoclonal antibodies, that bind to influenza virus comprising HA of the H3 subtype, e.g., H3N2, and have a broad neutralizing activity against such influenza virus. Described are polynucleotides encoding the binding molecules, their sequences and compositions comprising the binding molecules and methods of identifying or producing the binding molecules. The binding molecules can be used in the diagnosis, prophylaxis, and/or treatment of influenza virus H3N2 infection. The binding molecules may provide cross-subtype protection, such that infections with H3, H7, and/or H10-based influenza subtypes can be prevented and/or treated.

Abstract: Described are methods for preparing virosomes comprising the steps of: (a) providing an enveloped virus, and optionally inactivating the virus; (b) solubilizing the viral envelopes in a first solubilizing agent; (c) pre-solubilizing exogenous components in a second solubilizing agent; (d) adding the pre-solubilized exogenous components to the solubilized viral envelopes; and (e) reconstituting virosomal membranes by removing the solubilizing agent. According to the disclosure, the viral envelopes and the exogenous components are (pre-)solubilized at a temperature below 33° C.
Abstract: The disclosure relates to isolated antibodies and antigen-binding fragments that bind to the G protein of RSV and which are capable of neutralizing RSV A and B subtypes, and the use thereof in the diagnosis, prophylaxis, and/or treatment of RSV infections.

Abstract: A packaging cell line that complements recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line may be derived from primary, diploid human cells that are transformed by adenovirus E1 sequences either operatively linked on one DNA molecule or located on two separate DNA molecules, the sequences being operatively linked to regulatory sequences enabling transcription and translation of encoded proteins. Also disclosed is a cell line derived from PER.C6® that expresses functional Ad35 E1B sequences. The Ad35-E1B sequences are driven by the E1B promoter or a heterologous promoter and terminated by a heterologous poly-adenylation signal. The cell lines are useful for producing recombinant adenoviruses designed for gene therapy and vaccination, and can also be used for producing human recombinant therapeutic proteins such as human growth factors and human antibodies.
