Nanobodies targeting the interaction interface of programmed death receptor 1 (PD-1)/PD-1 ligand 1 (PD-1/PD-L1)

Targeting the interaction interface is an effective strategy to obtain programmed death receptor 1 (PD-1)/PD-1 ligand 1 (PD-L1) nanobody blockers. To validate this strategy, the interaction...
