Abstract:	BACKGROUND: Ischemia-reperfusion injury after organ transplantation is a major cause of delayed graft function. We showed earlier that antisense oligodesoxynucleotides (ODN) for intercellular adhesion molecule-1 (ICAM-1) ameliorate reperfusion injury after acute ischemia. This study tested the hypothesis that antisense ODN for ICAM-1 prevents ischemia-reperfusion injury and facilitates immediate graft function in a rat autotransplantation model. METHODS: Both kidneys were removed from male Lewis rats and re-implanted the left kidney after 30 minutes of cold ischemia time. The warm ischemia time was 60 minutes. Sham operated, uninephrectomized animals served as controls for renal function and histology. ICAM-1 antisense ODN (5 mg/kg), reverse ODN, or saline-vehicle were administered to donor animals i.v. six hours before autotransplantation. Glomerular filtration rate (insulin clearance), and serum creatinine concentrations were measured 24 hours post-transplantation. Tubular necrosis severity was assessed by histological grading scale. ICAM-1 expression was determined by immunohistochemistry and Western blot. RESULTS: Antisense ODN decreased ICAM-1 expression and leukocyte infiltration significant. Antisense ODN-treated animals showed significantly less tubular necrosis, than controls. Serum creatinine of antisense ODN-treated animals (N = 6) was 0.55 +/- 0.02 mg/dl compared to 1.92 +/- 0.07 mg/dl in reverse ODN-treated controls (N = 6; P < 0.01), 24 hours after transplantation. Antisense ODN-treated animals had normal GFR (0.93 +/- 0.07 ml/min/kidney wt) compared to sham-operated animals (0.95 +/- 0.09 ml/min/kidney wt), while autotransplanted animals treated with reverse ODN or saline-vehicle were all anuric. The ischemia-reperfusion-induced up-regulation of MHC class II was totally prevented by antisense ODN. CONCLUSIONS: ICAM-1 inhibition ameliorates ischemia-reperfusion injury and prevents delayed graft function. Antisense ODN-treatment of donors or donor organs for ICAM-1 may be useful for the prevention of reperfusion injury in human renal transplantation.
