CD274 and non-small cell lung carcinoma: Compared with the studies which reported that TGF-β1-induced EMT increased PD-L1 expression in NSCLC and TNBC, our data identified a novel pathway about TGF-β1-mediated PD-L1 glycosylation, further expanding the understanding of the regulatory mechanisms and cellular functions underlying PD-L1 glycosylation.
