Holt et al. describe an anti-HIV strategy in which human hematopoietic stem/progenitor cells are modified with zinc-finger nucleases to knock out the viral co-receptor CCR5. Transplantation of these cells into mice confers resistance to HIV, as shown by higher human T-cell counts and lower viral loads compared with animals that received unmodified cells.
