摘要
目的:探讨CD4+CD25+调节性T细胞、CD4+CD25+Foxp3+调节性T细胞及其他免疫细胞在川崎病(KD)免疫学发病机制中的作用。方法:选取急性期KD患儿58例,其中31例无冠状动脉损害(CAL),27例有CAL,另选取同期健康儿童30例作为对照组。采用流式细胞仪测定外周血CD4+CD25+调节性T细胞、CD4+CD25+Foxp3+调节性T细胞及其他免疫细胞比例并分析其变化规律。结果:急性期KD患儿外周血中,CD4+CD25+、CD4+CD25+Foxp3+、CD3+CD8+、CD3-CD(16+56+)细胞比例明显降低,CD4+/CD8+、CD19+CD23+、CD3-CD19+细胞亚群比例明显增高(P均<0.01)。无CAL的KD患儿与有CAL的KD患儿调节性T细胞亚群比较差异无统计学意义(P>0.05)。结论:KD急性期存在免疫调节功能紊乱,可能与CD4+CD25+调节性T细胞和CD4+CD25+Foxp3+调节性T细胞减少密切相关。
Objective: To investigate the role of CIM+CD25+ regulatory T cells, CD4+ CD25* Foxp3+ regulatory T cells and the other immune cells subsets in immunological pathogenesis of Kawasaki disease (KD). Methods: Total 58 children with KD were enrolled in KD group, including 27 cases with coronary artery lesion (CAL) and 31 cases without coronary artery lesion (non-CAL), 30 agematched health children were included in control group. Applying flow cytometer (FCM) to determine the proportion of CD^4+ CD25+ regulatory T ceils, CD4+ CD25 + Foxp3 + regulatory T cells and the other immune cells subsets. Results: The proportion of CD4+ CD25 + regulatory T cells and CD^4+CD25+ Foxp3+, CD3+CD8+, CD3-CD( 16+56+) cells in peripheral blood from children with KD at acute phase were significantly lower than those of control group ( P〈0.01 ). The proportion of CD4+/CD8+, CD19+ CD23+, CD3- CD19+ increased significantly. There was no statistical difference between the proportion of immune cells subsets from cases with CAL and cases with non-CAL. Conclusion: Immune dysfunction is involved in the acute stage of KD, the decrease of CD4+ CD25+ and CD4+ CD25+ Foxp3+ regulatory T cells may be correlated with this.
