1 Programmed cell death ligand-1 (PD-L1) expression of alveolar macrophages.
Programmed cell death ligand-1 (PD-L1) expression of alveolar macrophages. (A) Alveolar macrophages in the normal lung tissue are expressing PD-L1 on their membrane and/or cytoplasm. (B) Alveolar macrophages in the pulmonary adenocarcinoma tissue are expressing PD-L1 on their membrane and/or cytoplasm (arrows). Some multinucleated giant cells are also observed around the PD-L1-expressing tumour cells. (magnification, ×200). Tomoyuki Igarashi et al.
