Interleukin tumor transfection studies

First clinical human gene therapy trials with polyplexes were performed using cancer vaccines based on autologous patient tumor cells. These were modified ex vivo with interleukin-2 pDNA. To obtain high level transfection rates of patient s primary tumor cells, Tf-PLL/pDNA polyplexes linked with inactivated endosomolytic adenovirus particles were applied [221]. Polymer-based in vivo human gene transfer studies were performed with PEGylated PLL polyplexes, delivering CFTR pDNA to the airway epithelium of cystic fibrosis patients [222],...
