Therapeutic globin gene delivery using lentiviral vectors.
The severe hemoglobinopathies, including beta-thalassemia major and sickle cell anemia, are candidate diseases for a genetic treatment based on the transfer of a regulated globin gene in autologous hematopoietic stem cells. Two years ago, May et al reported that an optimized beta-globin transcription unit containing multiple proximal and distal regulatory elements harbored by a recombinant lentiviral vector could efficiently integrate into murine hematopoietic stem cells and express therapeutic levels of the human beta-globin gene. Here, we review the advantages afforded by lentivirus-mediated globin gene transfer and recent studies based on this strategy.
