Expression and Significance of RANTES and MCP-1 in Renal Tissue With Chronic Renal Allograft Dysfunction
1Nephrology Department of Guilin 181st Hospital, Guangxi Key Laboratory of Metabolic Diseases Research, Guangxi, China.
Background:
To investigate the expression of RANTES (regulated upon activation, normal T-cell-expressed and -secreted) and monocyte chemoattractant protein-1 (MCP-1) in renal allografts with chronic renal allograft dysfunction (CRAD), and explore its relationship with interstitial fibrosis and tubular atrophy (IF/TA).
Methods:
An immunohistochemical assay and computer-assisted, genuine colored image analysis system were used to detect the expression of RANTES and MCP-1 in renal allografts with CRAD. The relationship among the expression level of MCP-1, RANTES, and the grade of inflammatory cell infiltration, interstitial fibrosis, and tubular atrophy in renal allografts were analyzed. Ten specimens of healthy renal tissue were used as controls.
Results:
Compared to the normal tissues, the expressions of RANTES and MCP-1 were significantly higher in the renal tissues with CRAD (P < .001), and the expressions tended to increase along with the pathological grade of IF/TA. The expression of RANTES and MCP-1 were positively correlated with the pathological grades of IF/TA (r = 0.940 and 0.954 respectively, P < .001 for both).
Conclusion:
In renal allograft tissue with CRAD, the up-regulated expressions of RANTES and MCP-1 may be related to the progression of chronic renal allograft dysfunction and allograft fibrosis.
