Figure 3

The model with programmed expansion and contraction of latently infected cells can generate viral blips with reasonable amplitude and duration. Inline graphic, Inline graphic. Column A: Inline graphic. Activated latently infected cells divide about Inline graphic times over an interval [4],[6] days. No statistically significant decay of the latent reservoir is observed. Column B: Inline graphic. The latent reservoir decays at a very slow rate. This realization shows a half-life of Inline graphic months. Column C: Inline graphic. Activated cells divide about Inline graphic times over the same time interval. The latent reservoir decays more quickly than it does in B, corresponding to a half-life of roughly Inline graphic months. The other parameter values used are listed in Table 1. The blue horizontal line represents the detection limit of 50 RNA copies/mL.
