As shown in Figures 3(c) and 3(d), the percentages of MDSCs and CD68+CD163+M2-like macrophages did not show clear difference in NSCLC patients with lung, brain or bone radiation, but after radiotherapy, the percentages of MDSCs in NSCLC patients with brain radiation were significantly less than NSCLC patients with lung and bone radiation. The gene discussed is CD68; the disease is non-small cell lung carcinoma.
