PD-L2 is associated with lineage-related transcriptional programs distinct from PD-L1 in primary mediastinal large B-cell lymphoma.
Different immune checkpoint signals control distinct subtypes of aggressive lymphoma, suggesting refined combination immunotherapy strategies.
This retrospective molecular characterization of primary mediastinal large B-cell lymphoma (PMBL) demonstrates that PD-L2 and PD-L1 are regulated by divergent transcriptional programs, with PD-L2 linked to lineage-specific gene networks. The findings have implications for understanding partial PD-1 blockade resistance and for designing combinations targeting both checkpoint ligands in PMBL.
