Abstract
A method for enhancing the efficiency of transduction of a recombinant AAV into a target cell is provided. The target cell is infected with a recombinant adeno-associated virus comprising a selected transgene under the control of regulatory sequences. The infected cell is contacted with an agent which facilitates the conversion of single stranded recombinant virus to its double stranded form. When this conversion occurs in the target cell, enhanced transduction of the recombinant virus into said target cell results. The agent can be a helper virus providing a gene which facilitates the conversion, or an agent to which the infected cell is exposed, which facilitates the conversion. In a similar manner, a novel recombinant AAV is provided which contains the facilitating gene and the transgene. The methods may be performed ex vivo or in vivo.
