Abstract
The present invention provides a strategy that allows for selective switching off of both transgene and viral gene expression in tissues where such expression is undesirable. The present invention employs a vector containing a tissue specific promoter that drives expression of Cre recombinase gene in tissue where transgene expression is undesirable. As a result of Cre recombinase expression, the same or another vector that expresses the transgene in that tissue will be cut by the action of the Cre recombinase into several pieces due to LoxP sites that are strategically placed within the vector backbone. Consequently, unwanted transgene as well as viral gene expression are prevented.
