摘要:
A method for treating human tumours by gene therapy is disclosed. In particular, defective recombinant viruses with a sequence coding for a human tumour-specific antigen, and the use thereof for treating or preventing human tumours, as well as producing specific cytotoxic T-cells (CTLs) in vitro or ex vivo, are disclosed. Pharmaceutical compositions comprising said viruses, particularly in injectable form, are also disclosed.
摘要:
Recombinant adenoviruses comprising a heterologous DNA sequence, preparation thereof, and use thereof for the treatment and/or prevention of cancer.
摘要:
The invention concerns the field of gene therapy and the treatment of tumours. More particularly, the invention concerns the insertion of a gene coding for the iodine specific carrier (Na+/I- symporter) (NIS) in tumour cells using an adenoviral vector to promote the accumulation of iodine in said cells. The invention also concerns the defective recombinant adenoviruses for replication comprising the nis gene and the use of said vectors in a method for treating cancers combining nis gene transfer into tumour cells and metabolic radiotherapy.
摘要:
The present invention relates to new viral vectors derived from adenoviruses, their preparation and utilization in gene therapy. It relates particularly to deffective recombinant adenoviruses wherein the IVa2 gene at least is inactivated.
摘要:
A medicinal combination of at least one immunosuppressive agent and at least one recombinant adenovirus with a genome that includes a first recombinant DNA containing a therapeutic gene, and a second recombinant DNA containing an immunoprotective gene, for consecutive, intermittent and/or simultaneous use in in vivo and/or ex vivo exogenic transfections.
摘要:
Modification of internal sites of the adenovirus fiber protein and hexon protein permit effective targeting of adenovirus vectors. Accessible sites to redirect adenovirus targeting were identified. The HVR5 loop of the hexon protein and the HI loop of the fiber protein (knob) were highly permissive for the insertion of foreign protein sequences, which apparently did not impact on the viability and productivity of corresponding viruses. Accessibility and functionality of the epitope strongly depend on the size of the neighboring spacers. Other results suggest that short targeting peptides can be effectively fused to the C-terminus of the fiber protein. In a specific embodiment, a series of adenovirus vectors modified at the HVR5 site, the fiber protein HI loop, or the fiber protein C-terminus to target urokinase-type plasminogen activator receptor bearing cells were prepared. Such vectors are particularly useful for targeting the vasculature, e.g., for gene therapy of cancers or cardiovascular conditions.
摘要:
Recombinant viruses comprising a heterologous DNA sequence coding for a lipase involved in lipoprotein metabolism. The invention also concerns the preparation and use in therapy of said recombinant viruses, especially for the treatment or prevention of dyslipoproteinemia-related pathologies.
