Figure 2From: A consensus surface activation marker signature is partially dependent on human immunodeficiency virus type 1 Nef expression within productively infected macrophagesVariable expression of typical receptors on CD14+ monocytes from normal blood donors. Monocytes were double-labeled for CD14 and the indicated markers and the percentage of positively labeled cells in the CD14+ fraction was quantified by flow cytometry. Two of the donors, Do4787 (brown) and Do3528 (deep blue) were used in the longitudinal analyses of HIV-infected macrophages (Figure 3).Back to article page
