    摘要: Cells capable of at least, in part, complementing adenovirus E2A function of an adenovirus defective in E2A function. Such cells include a nucleic acid encoding adenovirus E2A or a functional part, derivative and/or analogue thereof, integrated into the genome of the cell. Preferably, the cell has E2A nucleic acid derived from a temperature sensitive adenovirus such as adenovirus ts125. Methods for producing an adenovirus particle containing an adenovirus vector with a functional deletion of E2A. Such a method involves providing a cell as previously described with the functionally deleted adenovirus vector, culturing the cell, and harvesting the virus particle. The functional deletion can comprise a deletion of at least part of the nucleic acid encoding E2A. In such a method, the nucleic acid encoding adenovirus E2A in the genome of the cell preferably has no sequence overlap with the vector which leads to replication competent adenovirus and/or to the formation of an adenovirus vector comprising E2A function. In the method, the adenovirus vector preferably further comprises a functional deletion of E1-region encoding nucleic acid. Adenovirus vectors comprising a functional deletion of adenovirus E2A, preferably a deletion of at least part of the nucleic acid encoding E2A. Preparations of adenovirus vector containing adenovirus particles wherein the adenovirus vector comprises a functional deletion of E2A. Such an adenovirus vector preferably further includes a deletion of nucleic acid encoding E1-region proteins, and may be free of adenovirus vectors comprising E2A function. Methods for providing cells of an individual with a nucleic acid of interest, without risk of administering simultaneously a replication competent adenovirus vector, comprising administering the individual one of the previously described preparations.

    摘要: The present invention relates to a synthetic transfection system comprising as a carrier a cationic, water soluble or water dispersible polyphosphazene. In addition, it relates to a method for introducing DNA fragments in target cells, comprising contacting these DNA fragments with a polyphosphazene which is at least partially substituted with cationic substituents and subsequently contacting the obtained transfection system wits target cells. Finally, the invention involves the use of a polyphosphazene which is at least partially substituted with cationic substituents as transfection vehicle.
