- Successful transduction of liver in hemophilia by AAV-Factor IX and limitations imposed by the host immune responseCatherine S Manno
The Children s Hospital of Philadelphia, 3615 Civic Center Boulevard, Philadelphia, Pennsylvania, 19104, USA
Nat Med 12:342-7. 2006..We conclude that rAAV-2 vectors can transduce human hepatocytes in vivo to result in therapeutically relevant levels of F.IX, but that future studies in humans may require immunomodulation to achieve long-term expression...
