Figure 9. Numerical simulations of the homeostasis model (Eq. (7)) and sensitivity tests of several parameters.

Figure 9

The system is at steady state and at Inline graphic drug is applied. A, D, G and J: the latent reservoir size; B, E, H and K: viral load; C, F, I and L: the ratio of Inline graphic to Inline graphic, i.e., the relative contributions to the latent reservoir persistence from ongoing viral replication and latently infected cell proliferation. A, B and C: the carrying capacity of total latently infected cells is Inline graphic. We use different proliferation rates: Inline graphic (blue solid), Inline graphic (green dash-dotted), and Inline graphic (red dashed). The black solid line represents the detection limit. D, E and F: Inline graphic is fixed. Different carrying capacities of the total latently infected cells are used: Inline graphic (green dashed), Inline graphic (blue solid), Inline graphic (red dash-dotted). G, H and I: we use different fractions of infections that result in latency: Inline graphic (red dashed), Inline graphic (blue solid), and Inline graphic (black dotted). J, K and L: we use different drug efficacies: Inline graphic (red dashed), Inline graphic (blue solid), Inline graphic (black dotted). Inline graphic and the carrying capacity Inline graphic are fixed for the last two rows. The other parameter values used are listed in Table 1.
