Gene editing using a zinc-finger nuclease mimicking the CCR5Δ32 mutation induces resistance to CCR5-using HIV-1

Abstract excerpt

OBJECTIVES: To characterize a new zinc-finger nuclease (ZFN) that targets close to the sequence of the 32 bp deletion polymorphism in the CCR5 gene, and to generate cells resistant to HIV-1 strains that use CCR5. CCR5Δ32 is a naturally occurring deletion that provides genetic resistance to R5-tropic HIV-1. The specificity and efficacy of a newly identified target for CCR5 gene editing, near the CCR5Δ32 sequence...
