An initially uninfected IDU who subsequently becomes infected. Here we observe a significant drop in uninfected CD4+ T cell levels (solid line) characteristic of the infection. An equilibrium is eventually reached where x = 317 cells/μL, y = 43 cells/μL, r = 1.09 × 1014 molecules/μL and a = 4.94 × 1012 molecules/μL. The concentration of infected cells is represented by the dashed line and ROS by the dashed-dotted line. For clarity the time course of antioxidants has been scaled; the dotted line plots 10a.
