  • Patent number: 6803234
    Abstract: The present invention relates to a gene delivery vehicle comprising a recombinant adenovirus having a tropism for a primary human chondrocyte. By efficiently transducing a nucleic acid of interest into a primary chondrocytes, the gene delivery vehicle is able to at least in part improve the counteraction of cartilage disease. In one embodiment the recombinant adenovirus comprises a deletion in the gene encoding for fiber protein, which is replaced by a nucleic acid sequence encoding at least part of a fiber protein of a B-type adenovirus.

  • Publication number: 20040115620
    Abstract: The invention provides a method for identifying an adenoviral replicon capable of eliminating a target cell, comprising contacting a representative cell with said adenoviral replicon and observing any detrimental effect. Once said replicon has been identified, it can be used to specifically eliminate certain cells involved in disease, for instance tumor cells. Preferably, said replicon contacts, enters and replicates predominantly in diseased cells, causing a detrimental effect in said cells, while in non-diseased cells no or a tolerable detrimental effect is induced. Preferably, said adenoviral replicon comprises a recombinant adenovirus with a fusion between DNA from Ad5 and subgroup B adenoviral DNA. Methods for producing and purifying a replicon according to the invention is also herewith provided.

  • Publication number: 20040043489
    Abstract: Adenoviral vectors can be used in vaccines to cause antigen-presenting cells to display desired antigens. Disclosed is a vector and associated methods that transduce antigen-presenting cells better than currently available vectors, enabling the vector to be delivered in lower doses, and thus improves the efficiency of adenoviral vaccine technology.

  • Publication number: 20030171336
    Abstract: A packaging cell line capable of complementing recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line is preferably derived from primary, diploid human cells transformed by adenovirus E1 sequences either operatively linked on one or two DNA molecules, the sequences operatively linked to regulatory sequences enabling transcription and translation of encoded proteins. Also, a cell line derived from PER.C6 that expresses functional Ad35 E1B sequences. The Ad35-E1B sequences are driven by the E1B promoter and terminated by a heterologous poly-adenylation signal. The new cell lines are useful for producing recombinant adenoviruses. The cell lines can be used to produce human recombinant therapeutic proteins such as human antibodies. In addition, the cell lines are useful for producing human viruses other than adenovirus such as influenza, herpes simplex, rotavirus, and measles.

  • Publication number: 20030138955
    Abstract: The present invention relates to providing human primary fibroblasts with a nucleic acid of interest with, among others, the purpose to improve the taking of for example. skin transplants. Particularly, methods of transducing fibroblasts with the nucleic acid of interest by means of gene delivery vehicles, in particular chimeric recombinant adenovirus (having an improved tropism for human primary fibroblasts) based gene delivery vehicles. The present invention is exemplified by an adenovirus serotype 5 genome based vector with an adenoviral fiber protein of a B-type or a D-type adenovirus, in particular adenovirus types 40 or 16, and wherein the nucleic acid of interest encodes a protein which improves angiogenesis and/or neurovascularization, in particular myogenin or MyoD.

  • Publication number: 20030096415
    Abstract: A method for delivering a nucleic acid of interest to a host cell (“gene therapy”) using a gene delivery vehicle based on adenoviral material. The gene delivery vehicle delivers the nucleic of acid of interest to the host cell by associating with a binding site and/or a receptor present on adenovirus serotype 5 Coxsacki adenovirus receptor (“CAR”)-negative cells. The binding site and/or receptor is a binding site for adenovirus subgroup D and/or adenovirus subgroup F. Associated methods and pharmaceutical compositions are also disclosed.

  • Publication number: 20030073072
    Abstract: Methods and vector systems for generating chimeric recombinant adenoviruses. These hybrid adenoviruses contain a genome that is derived from different adenovirus serotypes. In particular, novel hybrid adenoviruses are disclosed that have improved properties for gene therapy purposes. These properties include, but are not limited to, a decreased sensitivity towards neutralizing antibodies, a modified host range, a change in the titer to which adenovirus can be grown, the ability to escape trapping in the liver upon in vivo systemic delivery, and absence or decreased infection of antigen presenting cells of the immune system, such as macrophages or dendritic cells. These chimeric adenoviruses thus represent improved tools for gene therapy and vaccination, since they overcome the limitations observed with the currently used serotype subgroup C adenoviruses.
