One of the main challenges in gene therapy research is the delivery of the genetic material to particular cells. Retroviruses are most commonly used as the vehicles for inserting genes into the cellular genome. We have designed a set of novel viruses that show great promise for gene therapy. The viruses consist of retrovirus proteins on the interior and the proteins of other viruses on the surface. These " pseudotyped" viruses have been made with surface glycoproteins from a family known as the alphaviruses and from the Ebola virus. The retroviruses with the alphavirus glycoproteins, constructed in a collaboration with the Kuhn laboratory, have properties that make them superior to any of the other retroviruses previously utilized and have been demonstrated to have strong capacities for gene transfer to the liver and the central nervous system. The retroviruses with the Ebola virus glycoprotein have unique capabilities to enter the lung through the airway and may have utility for gene therapy for cystic fibrosis. We have discovered a technique for greatly increasing the effectiveness of the retroviruses with the Ebola virus glycoprotein and have also acquired evidence indicating that the natural host of the Ebola virus may be a bird.
