6. The biopsy tumor key protein measurements demonstrate substantial between-tumor variation in expression ratios of these proteins and suggest that programmed cell death 1 ligand 2 PD-L2 is present in some tumors at levels sufficient to contribute to programmed cell death-1 PD-1-dependent T-cell regulation and possibly to affect responses to PD-1- and programmed cell death 1 ligand 1 PD-L1-blocking drugs.
