CXCR2 deficiency causes decreased leukocyte rolling and adhesion in brain vessels after i.c.v. LPS injection. Intravital microscopy was performed on wild-type (A), CXCR2^−/− (B), and CXCL1^−/− mice (C) 4 h after LPS i.c.v. injection. The results of rolling flux (D) and leukocyte adhesion (E) are presented as the means ± SEM. n = 4–6 mice per group. **P < 0.01
