CA 2368185

The present invention demonstrates that polycationic, non-lipid:DNA formulations are resistant to nebulizer-induced degradation and are much more specific and efficient than lipid-based formulations in transfecting respiratory tract tissues in vivo. Results presented herein demonstrate that polyethyleneimine (PEI) formulations are about 10-fold more effective than previous lipid-based formulations when delivered in vivo by jet nebulizer. Therefore, aerosolized polyethyleneimine-based formulations are provided herein for use in targeting gene therapy via the respiratory tract.

La présente invention concerne des préparations d'ADN polycationiques non lipidiques, qui résistent à la dégradation induite par aérosol et sont beaucoup plus spécifiques et efficaces que les préparations lipidiques pour la transfection in vivo de tissus des voies respiratoires. Les résultats obtenus montrent que les préparations de polyéthylèneimine (PEI) de l'invention présentent une efficacité décuplée par rapport aux préparations lipidiques classiques lorsqu'elles administrées in vivo par aérosol. Ces préparations de polyéthylèneimine en aérosol peuvent donc être utilisées pour mettre en oeuvre une thérapie génique par les voies respiratoires.
