CXCR4 knockdown prevents inflammatory cytokine expression in macrophages by suppressing activation of MAPK and NF-κB signaling pathways

The expression of CXCR4 was detected in ALI lung tissue and alveolar macrophages. a Immunofluorescence analyzed a number of macrophages in ALI lung tissue. b Immunofluorescence analyzed the expression of CXCR4 in ALI lung tissue. c RT-qPCR analyzed CXCR4 expression in alveolar macrophages. CXCR4 in macrophage of lung tissue in control group (×200) and ALI group (×200). Data shown represent at least three independent experiments. *p？<？0.05, **p？<？0.01, and ***p？<？0.001 compared with control group. Error bars represent S
