HIV-1 infection in monocyte–macrophages from spleen and BM and intervention of ART in the frequencies on infected cells. Sorted monocyte–macrophages CD14+CD16+ cells were processed for RNA and DNA isolation and examined by ddPCR system as described in methods. Coloured dots are representations for the frequency of viral RNA or DNA of different treatment groups from spleen and BM cells. Dots in blue indicate the HIV-1 infected control group, dots in red are the HIV-1 infected and 2ART drug-treated group and dots in green represent HIV-1 infected and 4ART drug-treated group
