    摘要: The present invention describes recombinant adenoviral vectors modified by incorporating targeting ligands or label into viral capsid or structural proteins. In one embodiment, single-chain antibody was introduced into the minor capsid proteins pIIIa or pIX so that the adenoviral vector can be targeted to a particular cell type. In another embodiment, there is provided a noninvasive imaging strategy useful for monitoring the replication and spread of conditionally replicative adenoviral vectors. Viral structural proteins such as pIX capsid protein, core proteins mu, V and VII were expressed as fusion protein with a fluorescent label. Once incorporated into the virions, detection of the structural fusion protein label would indicate the localization of the disseminated viral progeny. The detected fluorescent signals also closely correlate with the level of viral replication and progeny production.

    摘要: The present invention provides a strategy that allows for selective switching off of both transgene and viral gene expression in tissues where such expression is undesirable. The present invention employs a vector containing a tissue specific promoter that drives expression of Cre recombinase gene in tissue where transgene expression is undesirable. As a result of Cre recombinase expression, the same or another vector that expresses the transgene in that tissue will be cut by the action of the Cre recombinase into several pieces due to LoxP sites that are strategically placed within the vector backbone. Consequently, unwanted transgene as well as viral gene expression are prevented.

    摘要: The present invention provides a chimeric viral vector system having a highly efficient in vivo gene delivery to cells after vascular administration and an intergrative capacity of heterologous gene sequences for stable genetic modification of cells after transduction. In this chimeric vector, an adenoviral vector is employed to deliver retroviral functions to a cell for local, in situ production of retroviral particles inside the cell by the construction of replication-defective adenoviral vectors which contain either retroviral “packaging” functions (retroviral genes gag, pol, env) and retroviral “vector” functions (retroviral LTR sequences flanking the “therapeutic” gene).
