Popis: | Gene transfer into the skin is a promising approach to treat inherited or acquired dermatological diseases and systemic monogenic deficiencies. For this purpose, the efficient and sustained gene delivery into keratinocytes is of critical importance. Recombinant adeno-associated virus (rAAV) vectors hold the potential to achieve a long-term gene transfer into various human organs. In order to evaluate this potential for skin gene therapy, human keratinocytes were transduced in vitro with rAAV vectors encoding the reporter genes beta-galactosidase (rAAV/LacZ) or green fluorescent protein (rAAV/GFP). Using rAAV/LacZ at a multiplicity of infection (MOI) of five transducing particles per cell, up to 70% of human keratinocytes were transduced within 48 h. This effect was independent of individual skin donors and different body areas serving as the source for keratinocyte isolation. rAAV had no significant influence on cell viability, but induced a growth arrest in transduced keratinocytes. This growth arrest was overcome by replating cells in fresh media. rAAV/GFP-transduced keratinocytes could be passaged several times, expressed GFP for up to 50 days, and passed the transgene to their daughter cells, suggesting that keratinocyto precursor cells were also transduced. Taken together, the results suggest that rAAV is a promising gene transfer vehicle for skin gene therapy. |
