Fig. 6: Inhibition of CXC chemokine receptor 2 (CXCR2) attenuates ischemia-reperfusion (IR)-induced inflammation.

The mice received intraperitoneal administrations of antagonist of CXCR2 (CXCR2(-)-IR) or vehicle (NC-IR) 1 h prior and 1 h after renal IR. A Immunofluorescence staining of Gr-1 in the kidney 6 h after renal IR. Scale bar, 100 μm. B Quantification of Gr-1-positive neutrophils. C Concentration of serum creatinine 24 h after renal IR. D ELISA of IL-6 in the kidney 6 h after renal IR. Data represent mean ± SEM. n = 6–8. **p < 0.01.
