Multiple organs (BM, LN, ORG, liver, lung, spleen, GI tract and FRT) were collected from EFdA-treated and untreated BLT mice at necropsy, 6 weeks post-infection (3 weeks following EFdA treatment initiation) to quantitate the levels of HIV-RNA, HIV-DNA, and CD4+ T cells. Here, CD4 is linked to infection.
