Abstract T-cell acute lymphoblastic leukemia T-ALL is a high-risk type of blood-cell cancer. We describe the improvement of a candidate therapeutic virus for virotherapy of leukemic cells. Virotherapy is based on the exclusive replication of a virus in leukemic cells leading to the selective removal of these malignant cells. To improve the safety of such a virus we constructed an HIV-1 variant that replicates exclusively in the presence of the nontoxic effector doxycycline dox . This was achieved by replacement of the viral TAR-Tat system for transcriptional activation by the Escherichia coli-derived Tet system for .
