    Abstract: A method for producing recombinant adeno-associated virus in the absence of contaminating helper virus or wild-type virus involves culturing a mammalian host cell containing an rAd/AAV hybrid virus, an AAV rep sequence and an AAV cap sequence under the control of regulatory sequences directing expression thereof. The rAd/AAV hybrid virus contains a rAAV construct to be packaged into an AAV virion in an backbone containing the adenoviral sequences necessary to express E1a and E1b gene products and to permit replication of the hybrid virus. The method of the invention permits replication of the hybrid virus and production of rAAV virion in this host cell in the absence of a helper virus and obviates a subsequent purification step to purify rAAV from contaminating virus.

    Abstract: A novel adenovirus E1/E4 expressing packaging cell line is provided, which permits the generation of recombinant adenoviruses deleted in both gene regions. The E1/E4 deleted recombinant adenovirus is capable of expressing a selected transgene product in cells in vivo or in vitro. This recombinant virus is useful in the treatment of genetic disorders.

    Abstract: A method for tolerizing a mammalian subject to administration of a live virus carrying a gene for delivery to a cell of the subject is disclosed. The method entails administering to the subject a suitable amount of an inactivated virus prior to administration of the live virus. The prior administration of the inactivated virus suppresses anti-virus cytotoxic T cells, permitting longer transgene persistence once the live virus is administered, and permitting effective readministration of live virus.

    Abstract: A thin film organic light emitting diode with edge emitter waveguide comprises, in sequence, a substrate, a waveguide, an anode, a hole transport layer, an electroluminescent layer, an electron injection layer and a cathode. Voltage applied between the anode and cathode causes the electroluminescent layer to emit light through the hole transport layer and the anode into the waveguide where the light is internally reflected within the waveguide and propagates through the length of the waveguide to be emitted through the edge of the waveguide. The electron injection layer also functions as a cladding layer to increase the efficiency of the waveguide. The non-emission edge of the waveguide may be sloped with a conductor layer to the anode and a conductor layer to the cathode forming a reflective surface to the non-emission edge.

    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.
