Clinical Significance
Many tumor cells are able to upregulate the expression of PD-L1 (programmed death ligand 1) as a mechanism to evade the body's natural immune response. Activated T-cells recognize the PD-L1 markers on the malignant cell, similar to the normal cell, rendering the T-cell inactive. Anti-PD-1 therapies can be used then to block the PD-1 receptor and so boost the effectiveness of cytotoxic T cells.
