Schematic of excision of integrated HIV-1 proviral DNA by (CRISPR)/CRISPR-associated 9 (Cas9). A guide RNA (gRNA) specific for the HIV-1 long terminal repeat (LTR) present at each end of the HIV-1 proviral genome is used together with Cas9. This results in cleavage at 2 sites that flank the HIV-1 genome and consequently the excision and subsequent degradation of the proviral DNA
