Increase in the number of alveolar macrophages in the BALF 24 hours postischemic stroke. A, Total number of cells recovered from BALF 24 and 72 hours following tMCAO (filled circle) or sham operation (open circle). B, Cellular compositions of BALF 24 and 72 hours following tMCAO. B, Representative plots showing percentage of CD45+ cells (left) and alveolar macrophages (right), which are defined as CD45+ Siglec F+ CD11b−. C‐E, Graphs showing percentage of CD45+ cells (C); percentage (D) and number (E) of alveolar macrophages of individual animals described in (B). tMCAO (filled circle) and sham operation (open circle). Data shown are combined results from two independent experiments with n = 6 animals per group (sham 24 hours; tMCAO 24 hours; sham 72 hours; tMCAO 72 hours). *P < .05; **P < .01. BALF, bronchoalveolar lavage fluid; NS, not statistically different; tMCAO, transient middle cerebral artery occlusion
