Figure 3.
ROS production by infiltrating neutrophils is decreased in CD36-null hosts. A–C, Brain leukocytes (A), monocytes/macrophages (B), and neutrophils (C) producing ROS measured by in vivo DHE staining and flow cytometry 72 h after MCAo in CD36 chimeric mice (n = 4 or 5 mice/group). The number of neutrophils producing ROS is reduced in the CD36 KO host accounting for the decrease of the ROS-positive leukocytes. Values are mean ± SE. *p < 0.05 versus WT host→WT BM. D, E, Median fluorescence intensity (MFI) of DHE signals analyzed by flow cytometry of in brain leukocytes (D), monocytes/macrophages (E), and neutrophils (F) (n = 4 or 5 mice/group). DHE MFI is proportional to the amount of cellular ROS. Values are mean ± SE. *p < 0.05 versus WT host→WT BM.
