Abstract:
Objective To observe the expression of nuclear factor-kappa B(NF-κ3)and monocyte chemnattractant protein-1(MCP-1),and the infiltration of mononuclear macrophage CD68 in lupus nephritis (LN).The association between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations is explored.MethodsNF-κB,MCP-1 and MΦ in renal biopsy specimens from 49 cases of LN were detected using immunohistochemical techeniques.Forty-nine cases of renal tissues were examined for NF-κB by in situ hybridization.The relationship between NF-κB,MCP-1 and MΦ with kidney pathology and clinical manifestations were analyzed.Results ①Compared with the control group ,the expression of NF-κB,MCP-1 and MΦ in LN was significantly higher(P＜0.01).The expression of MCP-1 positively correlated with MΦinfiltration and NF-κB(P＜0.01)in glomeruli and renal tubule and renal interstitium of LN.The expression of NF-κB,MCP-1 and the infiltration of MΦ in LN Ⅳ was significandy higher than non LN Ⅳ and the control group(P＜0.01,P＜0.05).There was no significant difference between renal NF-κB positive group and negative groups in the degree of the immunohistochemical and in situ hybridization examination(P＞0.05).②The histological activity index,urine protein volume(24 h)and serum creatinine in LN were significantly higher than the control group(P＜0.01),and the expression of NF-κB in LN was correlated with histological activity index,urine protein volume(24 h)and serum creatinine(P＜0.01,P＜0.01,P＜0.05).MCP-1 and CD68 expression in LN were correlated with histological activity index and urine protein volume(24 h),but not correlated with serum creatinine(P＞0.05).Conclusion NF-κB induced MΦ by activating MCP-1 may be one cause of kidney injury of LN.NF-κB signal pathway may act as a new therapeutic target for MΦinfiltration and proliferation inhibition in kidney.
