IL6 and brain ischemia: As reported previously, we show that cerebral ischemia significantly increases peripheral cytokine levels of IL-1β (sham control versus stroke + vehicle: 109.91 ± 20.08 pg/mL versus 209.24 ± 54.05 pg/mL; P < 0.01, Figure 3A), TNF-α (sham control versus stroke + vehicle: 594.02 ± 97.44 pg/mL versus 960.98 ± 125.63 pg/mL; P < 0.001, Figure 3B), IL-6 (sham control: 185.33 ± 20.17 pg/mL versus stroke + vehicle: 299.50 ± 41.52 pg/mL; P < 0.001, Figure 3C), and IL-17 (sham control: 2145.31 ± 124.27 pg/mL, versus stroke + vehicle: 2934.50 ± 204.76 pg/mL; P < 0.05, Figure 3D).
