In cancer, loss of feedback restriction between transcription factors can lead to increased local PD-L1 expression, which could limit the effectiveness of systemic treatment with agents targeting PD-L1. [28] CAR-T [29] and NK cells [30] targeting PD-L1 are being evaluated for treating cancer. pSTAT-1 and PDL-1 expressions also strongly ...
The expression of PD-L1 (programmed death-ligand 1; one of the immune checkpoints) has been demonstrated to be a good biomarker of PD-L1 blockade therapy in some cancers. [10] However, there is a need for better biomarkers as there are some predictive errors with PD-L1 expression. [10]
