Peripheral immune cell infiltration in ischemic brains at 3 and 7 days after stroke. (A) Representative dot plots depict the gating strategy used to differentiate the microglia (CD45intermediateCD11b+), peripheral myeloid cells (CD45highCD11b+) (pMyeloid), and lymphocytes (CD45highCD11b−). In pMyeloid cells, monocytes are further gated as CD45highCD11b+Ly6C+Ly6G−, and neutrophils as CD45highCD11b+Ly6G+ Ly6C−. Absolute counts of infiltrating monocytes, neutrophils, and lymphocytes at 3d (B) and 7d (C) after stroke were shown. N=4–5 sham and 6–8 stroke animals per group; *P < 0.05.
