Simulation results for NK cell-mediated antitumor cell killing and infected cells with various NK injection rates (${\lambda }_{NK}$). (A) Time courses of exogenous NK (exo-NK) cell populations for ${\lambda }_{NK}=0.0$ (NK$-$), 1.2, 3.2, and 5.2. ($t_1=3,\tau =0.1$). (B) Normalized population (percent) of uninfected cancer cells for ${\lambda }_{NK}=0.0$, 0.62, 1.2, 3.2, and 5.2. (C) Normalized OV population (percent) for ${\lambda }_{NK}=0.0$, 0.62, 1.2, 3.2, and 5.2. (D) NK cell-mediated antitumor killing (blue) and infected cell populations (red) at final time ($t=40$ d) for various injection rates [${\lambda }_{NK}=0.0$ (NK$-$), 0.62, 1.2, 3.2, and 5.2].
