Rheumatology:肾纤维细胞与狼疮性肾炎间质纤维化相关

2022-06-18 紫菀款冬 MedSci原创

研究狼疮性肾炎(LN)患者外周血和肾脏中纤维细胞的存在和特征,以及纤维细胞丰度与肾小管上皮细胞(RTECs)在LN纤维形成中的相关性。

目的:纤维细胞是来源于骨髓干细胞的产生细胞外基质(ECM)的细胞,有助于器官纤维化。该团队研究了狼疮性肾炎(LN)患者外周血和肾脏中纤维细胞的存在和特征,以及纤维细胞丰度与肾小管上皮细胞(RTECs)在LN纤维形成中的相关性。

方法:采用流式细胞术和共聚焦成像技术,用I型胶原(colI)、α-平滑肌肌动蛋白(α-SMA)、CD34和CD45对纤维细胞进行鉴定。分析LN患者纤维细胞水平与病理特征的关系。用LN血清处理的HK-2细胞测定RTECs在纤维细胞生成中的作用。

结果:狼疮性肾炎患者外周血中存在梭形纤维细胞(colIα-SMACD34CD45细胞),与健康对照组相比,梭形纤维细胞的丰度更高。在LN患者的肾小管间质中发现了肾纤维细胞(colI+α-SMA+CD45+细胞),其数量与慢性指标(包括间质纤维化和肾功能不全)的程度显著相关。用LN血清处理的HK-2细胞的上清液刺激外周血单个核细胞,导致显著的纤维细胞生成,通过添加IL-6中和抗体,纤维细胞被消除。

结论:LN患者血液和肾组织中纤维细胞明显增多,尤其是间质纤维化患者。纤维细胞可以从血细胞中分化出来,RTECs对其有积极的贡献。该研究结果表明,纤维细胞与肾小管间质纤维化之间可能存在联系,这可能是LN纤维化的一个新的治疗靶点
