  • Patent number: 10660854
    Abstract: A platform enabling the manufacture of thermostable vaccines by incorporating recombinantly expressed, viral envelope proteins in their native conformation into ether glycerophospholipid nanodisc structures that simulate the natural environment of the envelope proteins. The ether glycerophospholipids include ether-linked hydrophobic side chains, and are derived from or modeled after those found in thermophile bacteria, which increase thermostability, thereby significantly enhancing the vaccine's potency, enabling the production of highly multivalent vaccines incorporating multiple variants of the viral antigen, and improving stability and shelf-life.

  • Patent number: 9228205
    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.

  • Patent number: 8609402
    Abstract: The invention relates to vaccines comprising recombinant vectors, such as recombinant adenoviruses. The vectors comprise heterologous nucleic acids encoding for at least two antigens from one or more tuberculosis-causing bacilli. Also described is the use of specific protease recognition sites linking antigens through which the encoded antigens are separated upon cleavage. After cleavage, the antigens contribute to the immune response in a separate manner. The recombinant vectors may comprise a nucleic acid encoding the protease cleaving the linkers and separating the antigens. Further described is the use of genetic adjuvants encoded by the recombinant vectors, wherein such genetic adjuvants may also be cleaved through the presence of the cleavable linkers and the specific protease.

  • Patent number: 8221971
    Abstract: 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.

  • Patent number: 8052967
    Abstract: 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.
