Abstract
We reported a simple genome editing approach that can generate human immunodeficiency virus-1 (HIV) coreceptor defective cells, which may be useful for latent viral eradication treatment. Samples of bone marrow leftover after diagnostic procedures and crude bone marrow from aviremic HIV patients were subjected to zinc finger nuclease-mediated stop codon insertion into chemokine receptor 5 (CCR5) loci. Locked nucleic acid-based polymerase chain reaction was used to estimate the amount of insertion in the expandable CD34+ cells. The results showed that about 0.5% of CD34+ cells carried stop codon insertions in CCR5 loci. Cells edited using this simple protocol have the potential to be infused back into the bone marrow.
