The Mechanism of Action of Checkpoint Inhibition

FIG. 31:  Checkpoint inhibition is based on the concept that the tumor cell tries to reduce the activity of infiltrated T-cells acting on the tumor cell by blocking either the PD-L1 receptor or the programmed cell death protein 1 (PD1) receptor on the T-cell.[21]
