Dependence of the duration times of the interaction between NK and dendritic cells on the degradation time.

<p>Distribution of the duration time of the NK – dendritic cell interaction, as a function of the chemokines' degradation time, k: k = 600 s (open black bars, black continuous best fit line); k = 900 s (densely hatched red bars and red open squares best fit line) and k = 1200 s (sparsely hatched green bars and green filled triangles best fit line). The chemotactic parameter was set to . The lines are best fit to the trial function. Best fit parameters are: A (600s) = 803±28, t₁ (600s) = 70±6s, B (600s) = 78±2, t₀ (600s) = 450±6 s, σ (600s) = 250±14 s for k = 600s; A (900s) = 859±37, t₁ (900s) = 70±6s, B (900s) = 38±2.5, t₀ (900s) = 570±30s, σ (900s) = 380±40s for k = 900s and A (1200s) = 980±70, t₁ (1200s) = 66±6s, B (1200s) = 38±3, t₀ (1200s) = 630±200s, σ (1200s) = 550±90s.
