Mietzsch, M. Because helper-dependent adenovirus (HDAd) efficiently transduces grafted veins and confers long-term transgene expression, HDAd is an excellent candidate for delivery of vein graft-targeted gene therapy. Once inside a cell, this virus uses its own machinery (a reverse transcriptase enzyme) to produce DNA. If that’s an important protein, that can lead to illness. Their life cycle includes an integrated state in the DNA of the host chromosome. The viral vector needs to be engineered to be able to infect the target cell type, and then recombinant technology is used to give it the DNA or RNA that would correct or mitigate the genetic defect. 001-1% of infected cells.
