| 520 | 3 | |a The variant VP1-Z of the polyomavirus coat protein VP1 has been recently described as an engineered fusion protein of VP1 and the antibody binding domain protein Z. This construct is able to specifically bind and functionally present antibodies on the surface of viruslike particles of VP1-Z. Here we demonstrate that with the binding of Herceptin, an antibody directed against the receptor tyrosine kinase ErbB2, a cell typespecific targeting was established. ErbB2-positive cell lines were transduced with different plasmids encoding eGFP or β-galactosidase. With both reporter systems functional gene expression in transduced cells could be observed. The transduction was strictly dependent on the use of a ternary complex formed of VLPs of VP1- Z, Herceptin, and the reporter plasmid DNA. The use of single components or ErbB2-negative cell lines did not result in functional gene transfer. The transduction was also completely dependent on the use of chloroquine, a lysosomotropic reagent. This indicates that the complex is internalized by ErbB2-mediated endocytosis. | |
