OPTIMIZED LENTIVIRAL VECTOR FOR STEM CELL GENE THERAPY OF HEMOGLOBINOPATHIES

摘要

In certain embodiments an optimized derivative of the CCLc-βAS3-FB lentiviral vector termed (CCLc-mGata/ANK-CoreLCR-βAS3-FB), is provided which is capable of driving lineage-restricted expression of a beta-globin gene (e.g., an anti-sickling β-globin like gene (βA83)). In certain embodiments the vectors described herein comprise novel defined LCR HS core sequences (HS2(˜420 bp), HS3β40 bp), HS4(˜410 bp)) which can be used to replace the putative LCR HS sequences present within the “mini-LCR” (˜3.6 kb reduced to ˜1.2 kb) to produce an “optimized mini-LCR”.
