Distribution of CTLs within the tissue for decreasing p _i with p _N =0.5, and costant ${\mathit{k}}_{\mathit{i}}^{\mathit{+}}$. Plots showing the distribution of CTLs within the tissue at times corresponding to 700, and 1100 days respectively. These plots illustrate the spatiotemporal onset of immunoevasion. Parameter values p _N =0.5 and $k_i^{+}$ are constant. Solid line with chemorepellent, dashed line without.
