Fig 2. HRPII-mediated vascular leakage is blocked by antibody to IL-1β.
Mice were infused as in Fig 1, with HRPII plus an isotype antibody (Iso, positive control), HRPII plus anti-IL-1β antibody (experimental condition) or anti-IL-1β antibody alone (negative control). Untreated mice (no HRPII, no antibody) served as a further control. Vascular leakage in mice infused with HRPII/isotype is statistically significantly different from mice infused with HRPII/ anti-IL-1β, p = 0.01 (cerebellum) and p = 0.01 (cortex), by two-tailed t-test; p = 0.003 (cerebellum) and p = 0.06 (cortex) by ANOVA one-way variance with significance between HRPII/isotype and HRPII/ anti-IL-1β. Data are mean values +/-SEM for 6–12 mice per group accumulated over 3 independent experiments.
