Tumor-Associated Macrophages Promote PD-L1 Expression in Tumor Cells by Regulating PKM2 Nuclear Translocation in Pancreatic Ductal Adenocarcinoma

Scientists found that the ¹⁸fluoro-deoxyglucose positron emission tomography/computed tomography-based markers were positively associated with the expression of programmed cell death ligand 1, pyruvate kinase M2, both of which indicate poor prognosis in patients with pancreatic ductal adenocarcinoma.
