C/EBPalpha is required for generation of granulocyte-monocyte progenitors, but the subsequent role of C/EBPalpha in myeloid lineage commitment remains uncertain. We transduced murine marrow cells with C/EBPalpha-estradiol receptor (ER) or empty vector and subjected these to lineage depletion just prior to culture in estradiol with myeloid cytokines. This(More)
OBJECTIVE Inheritance of a mutant allele of the SDF1 gene delays the onset of human immunodeficiency virus type 1 (HIV-1) disease. Because the mutation lies in the 3' untranslated region of the gene, it was suggested that this mutation may upregulate transcription of the gene, resulting in more abundant SDF1, which in turn inhibits T-tropic HIV-1 and delays(More)
Lentiviral vectors (LVs) are the most recently developed viral-derived vectors for gene therapy applications, and have demonstrated much promise. The ability to transduce dividing and non-dividing cells, and sustain long-term transgene expression makes LVs uniquely desirable as gene therapy vectors. With advances in vector design and large-scale production,(More)
Lentiviral vectors (LVs) offer several advantages over traditional oncoretroviral vectors. LVs efficiently transduce slowly dividing cells, including hematopoietic stem-progenitor cells (HSCs), resulting in stable gene transfer and expression. Additionally, recently developed self-inactivating (SIN) LVs allow promoter-specific transgene expression. For many(More)
Newborn gene therapy, because it can prevent the damage caused by the onset of a disease, deserves specific attention. To evaluate gene transfer in tissues of newborn mice, we used a human immunodeficiency virus (HIV)-2 based lentiviral vector pseudotyped with vesicular stomatitis virus G glycoprotein expressing the green fluorescent protein reporter gene(More)

Lentiviruses are unique in their ability to infect both dividing and non-dividing cells. This makes the vectors derived from them particularly useful for gene transfer into non-dividing cells, including stem cells. Lentiviral vectors are becoming the vectors of choice for si/shRNA delivery. The utility of the lentiviral vectors will be enhanced if(More)
Retroviral vectors provide the means for gene transfer with long-term expression. The lentivirus subgroup of retroviruses, such as human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2), possesses a number of regulatory and accessory genes and other special elements. These features can be exploited to design vectors for transducing non-dividing as(More)
Lentiviral vectors are prime candidate vectors for gene transfer into dividing and non-dividing cells, including neuronal cells and stem cells. For safety, HIV-2 lentiviral vectors may be better suited for gene transfer in humans than HIV-1 lentiviral vectors. HIV-2 vectors cross-packaged in HIV-1 cores may be even safer. Demonstration of the efficacy of(More)
