Splet13. nov. 2024 · We also found that EpCAM inhibits antitumor immunity by activating the PD-1/PD-L1 pathway to suppress T-cell function. EpEX increases PD-L1 protein stability rather than mRNA level, while blockade of EGFR or MAPK signaling pathways attenuates EpEX-mediated stabilization of PD-L1 protein. SpletWhereas ICB against the PD-1/PD-L1 and CTLA-4 pathway has demonstrated clinical efficacy in a variety of cancers, the majority of patients do not respond. A major challenge for PD-1/PD-L1 blockade is that not all tumors rely on that pathway for immune evasion. B7x is independently expressed from PD-L1 in the vast majority of triple-negative ...

"SpletBesides membrane-bound PD-L1 and PD-1, soluble forms also exist. A soluble monomeric form of PD-L1 can be produced in vitro by cancer cell lines that express PD-L1 and by activated monocyte- derived dendritic cells (DCs) that also express high levels of PD-L1 (28, 29). It has been reported that soluble PD-L1 retains its inhibitory " - Pdl1 pathway
