M1 macrophage was activated in the RIR-injured mice model. The mice were grouped and subjected to RIR operation. The serum and kidneys were separated on days 1 and 3 after the operation. (A) Serum SCr and BUN levels in the RIR-injured mice. (B) Representative periodic acid–Schiff (PAS) staining images of kidneys form RIR-injured or sham mice. Bar = 50 μm. (C) Representative IHC images of CD86 in the kidneys from RIR-injured mice were performed. Bar = 50 μm. (D,E) The mRNA expression level of inflammatory factors, including MCP-1, TNF-α, IL-1β, CD86, and iNOS in the RIR-injured kidney was assessed by qRT-PCR. (F) Expression of CD86 in macrophages was assessed by flow cytometry. Data presented as means ± SD for groups of three mice. *p < 0.05, **p < 0.01, ***p < 0.001 vs. the sham group. #p < 0.05, ##p < 0.01 vs. the day 1 group.
