FIG. 2.

Decay rates of HIV-1 DNA in peripheral blood CD14⁺ monocytes (A), resting CD4⁺ T cells (B), and activated CD4⁺ T cells (C) in seven acutely infected patients taking HAART who had undetectable levels of plasma virus. Patients 1 to 6 had maintained undetectable levels of plasma viremia with one or two episodes of low-level plasma viremia (<100 copies/ml), while patient 7 had consistently maintained plasma HIV-1 RNA at levels lower than 50 copies/ml. Average decay slopes were estimated using linear random-effects regression (12) for one phase decay. The bold line in each panel represents the average slope and intercept of the decay in that cell compartment, and the dashed lines with different symbols represent predicted individual intercepts and decay slopes. The data are summarized in Table 2.
