摘要:
To achieve the foregoing and other objects, the present invention provides a retroviral vector comprising in its LTRs sequences, preferably sequences of an adeno-associated virus, for a targeted integration.
摘要:
The present invention relates to retroviral vectors carrying sequences encoding naturally occuring, antimicrobial peptides or derivatives thereof for the treatment of mammalian tumours, viral infections such as HIV infection and bacterial and fungal infections. In particular the present invention relates to retroviral vectors which undergo promoter conversion (Procon vectors) carrying such sequences. Since these vectors also carry tumour or virus specific regulatory elements, the therapeutic antimicrobial peptide will be delivered and expressed only in relevant, affected cells and not in innocent bystander cells.
摘要:
The present invention relates to the use of the WAP or MMTV regulatory sequences for the targeted expression of linked heterologous DNA sequences in human mammary cells, including human mammary carcinoma cells.
摘要:
The invention relates to retroviral expression vectors with cell-specifically modulatable promotors. The vectors can be used, for example, for the cell-specific expression of therapeutically valuable genes in gene therapy. The invention specifically relates to retroviral expression vectors containing at least the following elements, in a functional configuration: a) DNA sequences for the packaging of the vector RNA and for the cell-specific expression of proteins or peptides which are coded by heterologous DNA nucleotide sequences; b) one or more DNA nucleotide sequences coding for a protein or a peptide and characterized in that for cell-specific expression said DNA sequences contain a cell-specifically modulatable promotor region of a human endogenous retroviral DNA nucleotide sequence (HERV).
摘要:
The present invention relates to retroviral particles which are specifically applicable as safe gene transfer vehicles for targeted gene therapy and which are protected against complement mediated destruction in host organisms. For producing such retroviral particles a packaging cell is provided according to the present invention comprising a DNA construct coding for one or more complement inhibitors. Said inhibitors are derived from the complement system of the organism to be infected by the retroviral particle generated by the packaging cell.
摘要:
The present invention relates to a retroviral vector system comprising a packaging cell line that synthesize the core and enzymatic proteins of MLV virus from one or more gag and pol containing constructs and the envelope of MMTV virus from the same or an independent env containing construct, and to pseudotyped retroviral particles produced by culturing said retroviral vector system transfected with a MLV based retroviral vector, and isolation of said pseudotyped retroviral particles.
