SpletPD-L1 glycosylation is also essential for PD-1/PD-L1 interaction. A monoclonal antibody targeting glycosylated PD-L1 blocked interaction with PD-1, promoted PD-L1 internalization and degradation in triple-negative breast cancer (TNBC) cells in vitro, and eradicated TNBC cells in tumor-bearing mice ( 21 ). SpletIn-depth analysis of PD-L1 N192, N200 and N219 glycosylation suggests that glycosylation antagonizes GSK3β binding. In this regard, only non-glycosylated PD-L1 forms a complex with GSK3β and β-TrCP. We also demonstrate that epidermal growth factor (EGF) stabilizes PD-L1 via GSK3β inactivation in basal-like breast cancer.
