Location of the 5 CpGIs in the HIV-1 genome. The locations of the 5 CpGIs as described by Chavéz et al. [12] are indicated by red bars. CpGI long terminal repeat (LTR) and non-coding region (NCR) are located around the HIV-1 promoter location. CpGI ENV and env-tat-rev are located in the env gene. The fifth CpGI (3′ LTR) is located in the 3′ LTR region, where the antisense promoter region is found
