    摘要: A packaging cell line that complements recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line is preferably 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. The cell lines can also be used for producing human recombinant therapeutic proteins such as human growth factors and human antibodies. Also, the cell lines are useful for producing human viruses other than adenovirus such as influenza virus, herpes simplex virus, rotavirus, and measles virus.

    摘要: Provided are methods and means to increase the stability and/or the packaging capacity of recombinant adenoviruses, by overexpression of pIX in an adenoviral packaging cell, by retaining at least a part of the E1B-55K region in the recombinant adenoviral vector or by regulating pIX with a heterologous promoter. The invention further relates to methods and means for the production of such adenoviruses on complementing cell lines, wherein the early region 4 open reading frame 6 (E4-orf6) encoding nucleic acid is present in the adenovirus and wherein the E4-orf6 gene product is compatible with one or more products of the E1 gene products in the complementing cell, such that the adenoviral vector can be efficiently produced by the complementing cell.

    摘要: Adenovirus serotypes differ in their natural tropism. The adenovirus serotypes 2, 4, 5 and 7 all have a natural affiliation towards lung epithelia and other respiratory tissues. In contrast, serotypes 40 and 41 have a natural affiliation towards the gastrointestinal tract. The serotypes described, differ in at least capsid proteins (penton-base, hexon), proteins responsible for cell binding (fiber protein), and proteins involved in adenovirus replication. This difference in tropism and capsid protein among serotypes has led to the many research efforts aimed at redirecting the adenovirus tropism by modification of the capsid proteins.
