Targeting dual functions of PD-L1 for cancer therapy
Abstract Targeting immune checkpoint signaling with blocking antibodies has reached a limitation in the treatment of advanced cancers. Although antibodies that bind programmed death ligand 1 (PD-L1) are effective in blocking PD-L1's extracellular interaction with PD-1 receptor on T cells, the potential adaptive upregulation of PD-L1 and its recycling from intracellular compartment to the cell surface may compromise their efficacy. Importantly, the discovery of PD-L1's intracellular functions in cancer cells to promote thier survival and metabolism also highlight a mechanism by which tumor cells can gain resistance to cytotoxic therapy and call for a new strategy to target PD-L1. There is…
