Unlike monocytes and CD4+ T cells, the frequency of SIV-DNA in myeloid DCs (HLA-DR+CD11+) was extremely low during the acute phase of infection (day 11, mean: 0.015±0.004; day 14, 0.015±0.008 of DCs were infected) consistent with a previous report [87]. The gene discussed is CD4; the disease is infection.
