摘要: Genetic modification of hematopoietic stem cells with genes that inhibit replication human immunodeficiency virus-1 (HIV-1) could lead to development T lymphocytes and monocytic resistant HIV-1 infection after transplantation. We performed a clinical trial evaluate the safety feasibility this procedure, using bone marrow from four HIV-1–infected pediatric subjects (ages 8 17 years). obtained marrow, isolated CD34+ cells, in vitro transduction retroviral vector carrying arev-responsive element (RRE) decoy gene, reinfused into these no evidence adverse effects. The levels gene-containing leukocytes peripheral blood samples 1 year gene transfer/cell infusion have been extremely low. These observations support potential performing therapy for but emphasize need improved transfer techniques.
