viral vectors for gene therapy
. illustrated in Fig. 5.1.4. Inserting Transgenes into Replication-Defective Vectors Insertion of transgenes into the replication-defective HSV vectors is achieved by homologous recombination in eukaryotic. particles that contain very few viral gene sequences. In this instance, the desired transgene cassette is placed in a plasmid containing the viral genomic packaging/cleavage signals, in addition to. sites into appropriate genes for this purpose. Following diges-tion, only recombination or re-ligation events can yield DNA capable of being incorporated into infectious virus particles in the...
