Fig. 1. IFNAR1 is downregulated in MDSCs.

Fig. 1

a IFNAR1 levels on CD15+ PMN (left) and CD14+ Mon (right) from whole blood of healthy donors (HD) or cancer patients (CP). Individual results in 6 healthy donors and 22 cancer patients are shown. Mean ± SD of IFNAR1 expression is presented. P values were calculated in Mann–Whitney test. b IFNAR1 measured on PMN versus PMN-MDSCs (n = 3) or Mon versus M-MDSCs (n = 4) from the same patients. Fold change from IFNAR1 level in PMN or Mon in each patient is shown. c IFNAR1 levels on mouse splenic PMN-MDSCs and M-MDSCs from indicated s.c. tumor models analyzed by flow cytometry. Each dot represents the geometric mean of IFNAR1 levels in individual mice (n = 4 for B16 model, n = 7 for LLC mode, n = 4 for CT26 model). d IFNAR1 levels on splenic PMN-MDSCs and M-MDSCs from spontaneous tumor models analyzed by flow cytometry. Fold change over spleen of tumor-free mice (n = 3 for RET model, n = 5 for KPC model PMN-MDSC and n = 4 for M-MDSC). Mean and SD is shown. e IFNAR1 levels on PMN-MDSCs and M-MDSCs from spleen and indicated ascites tumors analyzed by flow cytometry. Each dot represents an individual mouse (n = 4 for EL4 model, n = 3 for MethA model). IFNAR1 levels is presented as fold changes from spleen cells. f IFNAR1 levels on PMN-MDSCs and M-MDSCs from spleen and mechanically dissociated tumors analyzed by flow cytometry. Each dot represents the geometric mean of IFNAR1 levels in individual mice. (n = 5 for B16-F10 and CT26 models and n = 4 for LLC model). In all panels, data are expressed as mean ± SD and the p values were calculated using unpaired two-sided Student’s t test. ns—p > 0.05.
