A&R:早期系统性红斑狼疮的纵向免疫细胞谱分析

2022-06-05 MedSci原创 MedSci原创

外周辅助T细胞、滤泡辅助T细胞(Tfh细胞)和独特的Ki67+增殖性免疫细胞亚群在系统性红斑狼疮(SLE)早期扩展,早期SLE的免疫学特征(Tfh细胞和CXCL10)随着时间的推移而演变。

目的研究系统性红斑狼疮(SLE)的免疫细胞谱及其纵向变化。

方法研究人员对来自9名早期SLE患者、15名确诊SLE患者和14名非炎症对照的冷冻保存的外周血单核细胞(PBMC)中采用了具有三种不同38-39标记组(免疫表型分型、T细胞/单核细胞和B细胞)的质谱检测。使用机器学习驱动的聚类、FlowSOM(流式细胞术自组织图)和tSNEt分布随机邻域嵌入)降维来识别早期和已确诊的SLE中的独特细胞群。对于9名早期SLE患者,在入组时、入组后6个月和入组后1年对PBMC应用纵向质谱分析。还通过Luminex多重检测对血清样品中的65种细胞因子进行了检测,并评估了细胞类型和细胞因子/趋化因子之间的关联。

结果外周辅助T细胞(Tph 细胞)、滤泡辅助T细胞(Tfh细胞)和几个Ki67+增殖亚群(ICOS+Ki67+CD8 T细胞、Ki67+调节性T细胞、CD19intKi67hi浆母细胞和Ki67hi PU.1hi 单核细胞)在早期SLE中增加,与早期类风湿性关节炎(RA)患者相比,早期SLE患者的变化更为显著。对早期SLE患者样本进行的纵向质谱和多重血清细胞因子分析显示,Tfh细胞和C-X-C基序趋化因子配体10CXCL10)在入组后一年下降CXCL13与早期SLE中几个扩增的细胞群呈正相关。

结论外周辅助T细胞、滤泡辅助T细胞(Tfh细胞)和独特的Ki67+增殖性免疫细胞亚群在SLE早期扩展,早期SLE的免疫学特征(Tfh细胞和CXCL10)随着时间的推移而演变。
