Background

Programmed Death-Ligand 1 (PD-L1) is an immune checkpoint molecule expressed on antigen-presenting cells and various cancer cells, critically involved in modulating T-cell-mediated immune responses. Its interaction with programmed cell death protein 1 (PD-1) on activated T cells delivers inhibitory signals that suppress cytotoxic activity and promote immune tolerance-a mechanism exploited by malignancies to evade immune surveillance. Elevated PD-L1 expression has been documented across multiple tumor types including non-small cell lung carcinoma, melanoma, and gastrointestinal cancers, correlating with advanced disease progression and poorer prognostic outcomes.
