SELL and brain ischemia: As shown in Figure 5a, after cerebral ischemia (i.e., DHCA), although CD62L did not change (P = 0.48), CD11b did show a small, but significant increase from arterial to venous (arterial median fluorescence intensity (MFI) 341 (286 to 543), venous 382 (313 to 638); P <0.01).
