摘要:
The invention provides cells and methods of using the cells for the propagation of replication-deficient adenoviral vectors. The cells comprise at least one heterologous nucleic acid sequence which upon expression produces at least one non-adenoviral gene product that complements in trans for a deficiency in at least one essential gene function of one or more regions of an adenoviral genome so as to propagate a replication-deficient adenoviral vector comprising an adenoviral genome deficient in the at least one essential gene function of the one or more regions when present in the cell.

The invention provides cells, particularly NCI-H460 cells and Calu-1 cells, for the propagation of replication-deficient adenoviral vectors. The cells are lung carcinomas with either a wild-type p53 gene or a heterozygous K-ras mutation. The cells comprise at least one adenoviral nucleic acid sequence, which upon expression produces a gene product that complements for at least one essential gene function of one or more regions of an adenoviral genome so as to propagate a replication-deficient adenoviral vector comprising an adenoviral genome deficient in the at least one essential gene function of the one or more regions when present in the cell.
摘要:
The invention provides a method of propagating an adenoviral vector. The method comprises (a) providing a cell comprising a cellular genome comprising a nucleic acid sequence encoding a tetracycline operon repressor protein (tetR), and (b) contacting the cell with an adenoviral vector comprising a heterologous nucleic acid sequence encoding a toxic protein. The heterologous nucleic acid sequence is operably linked to a promoter and one or more tetracycline operon operator sequences (tetO), and expression of the heterologous nucleic acid sequence is inhibited in the presence of tetR, such that the adenoviral vector is propagated. The invention also provides a system comprising the aforementioned cell and adenoviral vector.

摘要:
The invention provides a method of inducing an immune response against a human immunodeficiency virus (HIV) in a mammal. The method comprises administering to the mammal an adenoviral vector composition comprising one or more adenoviral vectors encoding two or more different HIV antigens, the production of which induces an immune response against HIV in the mammal. The invention also provides an adenoviral vector composition comprising four adenoviral vectors encoding an HIV clade A Env protein, an HIV clade B Env protein, an V clade C Env protein, and a fusion protein comprising an HIV clade B Gag protein and Pol protein, respectively.
摘要:
The invention provides an adenoviral vector comprising (a) at least a portion of an adenoviral genome comprising a major late transcription unit containing a terminal exon, wherein the terminal exon comprises a 5′ splice acceptor DNA sequence element and a 3′ polyadenylation signal sequence, and (b) a non-native nucleic acid sequence encoding a protein that does not contribute to the adenoviral vector entry into a host cell, wherein the non-native nucleic acid sequence is positioned within the terminal exon, such that the non-native nucleic acid sequence is selectively expressed in cells within which the adenoviral vector can replicate. The invention further provides an adenoviral vector composition and a method for treating or preventing a pathologic state in a mammal, comprising administering to the mammal the adenoviral vector composition of the invention in an amount sufficient to treat or prevent the pathologic state in the mammal.
