Abstract

Abstract:

BACKGROUND: The role of galactose lectin family proteins in transplantation immunity has been proposed, but there is currently no galectin-7 detection for auxiliary diagnosis of renal dysfunction in the perioperative period after renal transplantation. For renal transplant recipients, monitoring of galectin-7 may contribute to early diagnosis of renal dysfunction after renal transplantation, and buy time for clinical treatment.
OBJECTIVE: To detect the expression of galactose-7 in acute antibody mediated rejection after renal transplantation.
METHODS: Twenty-seven patients who were diagnosed as having acute antibody mediated rejection after renal transplantation by renal biopsy were enrolled, and another 10 patients without acute antibody mediated rejection after renal transplantation were selected as controls. Immunohistochemical staining and western blot assay were used to detect expression of galectin-7 in tissue and serum, respectively.
RESULTS AND CONCLUSION: Results of immunohistochemistry staining showed that under light microscope, in the control group, galectin-7 distributed in the surface microvilli of proximal tubule epithelial cells, but not in glomeruli, distal tubule, collecting duct and vein; in the acute rejection group, renal arteriole intima edema, tube wall fibrinoid necrosis, infiltration of renal glomerulus and tubule cells and mononuclear cells were found and galectin-7 only expressed in the surface microvilli of proximal tubule epithelial cells as well as in the arterial smooth muscle. The number of galectin-7 positive cells in the acute rejection group was significantly higher than that in the control group (P < 0.1). Western blot assay results showed that the protein expression of serum galectin-7 in the acute rejection group was higher than that in the control group (P < 0.05). These findings indicate that renal puncture for renal transplantation is safe and reliable, has no adverse effect on the patients and renal transplant. Galectin-7 detection has an important guiding significance for the auxiliary diagnosis of renal dysfunction during the perioperative period after renal transplantation.
