OBJECTIVE: Ischemia-reperfusion injury is known to cause organ failure, but the mechanisms of pathogenesis remain unclear. Inflammation is a factor in tissue destruction in ischemia reperfusion injury, and interleukin (IL)-1 is a key promoter of inflammation. DESIGN: Prospective, randomized, and controlled study. SETTING: University laboratory. SUBJECTS: Male mice 6-8 wks of age, in which genes for IL-1alpha and IL-1beta (IL-1alpha/beta deficient) and IL-1 receptor antagonist (IL-1RA deficient) are deleted by homologous recombination, and wild-type controls on a Balb/c background. INTERVENTIONS: In this study, the role of IL-1 on inflammatory cascades, including chemokine expression, inflammatory cell infiltration, and tissue destruction, was investigated in 45 mins of unilateral renal ischemic injury using IL-1alpha/beta-deficient mice and IL-1RA-deficient mice. In addition, the effects of IL-1 on chemokine expression in cultured tubular epithelial cells were investigated. MEASUREMENTS AND MAIN RESULTS: In vivo study revealed that the number of interstitial infiltrated neutrophils and macrophages, which accompanied the increase of the serum levels of keratinocyte-derived chemokine (KC) and macrophage inflammatory protein (MIP)-1alpha, respectively, significantly increased in IL-1RA-deficient mice. The number of interstitial infiltrated neutrophils correlated well with serum levels of KC at 24 hrs after reperfusion, whereas the number of interstitial infiltrated macrophages correlated well with the serum levels of MIP-1alpha and monocyte chemoattractant protein (MCP)-1 at 24 and 48 hrs after reperfusion, respectively. Likewise, in vitro study revealed that stimulation of tubular epithelial cells by IL-1beta and/or H2O2 sequentially induced KC, MIP-1alpha, and MCP-1 in both protein and messenger RNA levels, which is consistent with in vivo results. CONCLUSION: IL-1-dependent inflammatory cascades, followed by inflammatory cell infiltration and subsequent tissue destruction, may affect pathogenesis of renal ischemia-reperfusion injury.
