Leukocyte infiltrate in the brains of (A) wild-type, (B) MyD88
and (C) TRIF-mutant mice 24 hours following permanent middle cerebral artery occlusion. Inset: Graph shows the number of leukocytes per high-powered field (10×) in each group of mice. There were no differences in leukocyte infiltrate in the brains of all three groups of mice at 24 hours following focal ischemia (p = 0.3607). N = 9 mice, and n = 3 mice per wild type, MyD88−/− and Toll/interleukin 1 receptor domain-containing adaptor-inducing interferon β-mutant.
