In contrast, increase of PD-L1 or CSF1R expression was not observed in CD11b+HLA-DR– myeloid cells (representing PMN-MDSCs) (Supplemental Figure 7, I and J), confirming that the increased expression of PD-L1 and CSF1R was only associated with CD11c+ cells, and less associated with PMN-MDSCs, in patients with NSCLC. The gene discussed is CSF1R; the disease is non-small cell lung carcinoma.
