高迁移率族蛋白B1及其糖基化终产物受体在系统性红斑狼疮患者中的变化及其临床意义
Change and clinical significance of high mobility group protein B1 and its advanced glycation end product receptor in patients with systemic lupus erythematosus
摘要
Abstract
Objective To investigate the possible role of high mobility group box 1 protein (HMGB1) and its advanced gly‐cation end products receptor (RAGE) in the pathogenesis of systemic lupus erythematosus (SLE) .Methods The enzyme‐linked immunosorbent assay (ELISA) was used to determine the level of plasma HMGB1 in 52 cases of SLE (SLE group) and 40 healthy females undergoing physical examination (HC group) ,at the same time real time quantitative polymerase chain reaction (RT‐qPCR) was employed to detect the expression of HMGB1 and RAGE mRNA in peripheral blood mononuclear cells (PBMCs) .The correlation between plasma HMGB1 ,PBMCs HMGB1 and RAGE mRNA levels with clinical indicators was analyzed .Results The levels of plasma HMGB1 ,PBMCs HMGB1 mRNA in the SLE group were significantly higher than those in the HC group ,the differences were statistically significant (P< 0 .05) ,while the level of PBMCs RAGE mRNA had no statistical difference (P>0 .05);the Spearman correlation analysis showed that the level of plasma HMGB1 was positively correlated with antinuclear anti‐bodies titers and SLEDAI score in the SLE patients (P<0 .01) ,while had no obvious correlation with the other clinical and labora‐tory indicators(P>0 .05);the HMGB1 mRNA expression level was positively correlated with the RAGE mRNA expression level and SLEDAI scores(P<0 .01 ,P<0 .05) ,and had no obvious correlation with other clinical and laboratory indicators (P>0 .05) . Conclusion The abnormal expression of plasma HMGB1 and PBMCs HMGB1 mRNA in SLE patients prompts that which might be involved in the occurrence and development of SLE ,might participate in the immune and inflammatory regulation of SLE .关键词
