Figure 2.
STAT3p and Arg1 were determined in myeloid-derived suppressor cell (MDSC) subpopulations of stroke patients in comparison to healthy controls. Monocytic MDSCs (Mo-MDSCs; CD11b+/CD14+/HLA-DRdim/−) (A,D); granulocytic or polymorphonuclear MDSCs (PMN-MDSCs; CD11b+/CD15+/CD14−) (B,E); and early MDSCs (e-MDSC; Lin−/HLA-DR−/CD33+/CD11b+) (C,F) were measured in 10 stroke patients (black dots) in comparison to 10 healthy age-matched controls (white dots) on days 1, 3, and 5 after stroke. Arg1 (A–C) and STAT3p (D–F) were stained intracellularly and analyzed by flow cytometry (LSR II, BD). Data are provided as geometric mean fluorescence intensity (MFI). Median and interquartile range are provided.
