The expression intensity of PD-L1 on monocytes and macrophages. (a) Typical flow-cytometry results of PD-L1 surface expression on circulating monocytes from a healthy control, or their derived M1, M2 or GBM-educated macrophages. (b) ΔMFI values of PD-L1 on M1, M2 or GBM-educated macrophages, derived from circulating monocytes of healthy controls (n = 5). * P < 0.05, ** P < 0.01. (c) ΔMFI values of PD-L1 on GBM-educated macrophages, derived from circulating monocytes of healthy controls (n = 6), or GBM patients (n = 6). * P < 0.05. P values are achieved by t-test.
