Diabetologia:1型糖尿病和NOD小鼠胰腺淋巴结间质细胞的表型改变

2019-12-24 MedSci MedSci原创

当造血细胞(例如特定的树突状细胞亚群)和非造血细胞(例如淋巴结间质细胞[LNSC])向自身反应性T细胞呈递外周组织抗原时,两者均可介导淋巴结的耐受诱导。

当造血细胞(例如特定的树突状细胞亚群)和非造血细胞(例如淋巴结间质细胞[LNSC])向自身反应性T细胞呈递外周组织抗原时,两者均可介导淋巴结的耐受诱导。LNSCs通常调节T细胞的转运和存活,并通过发挥免疫抑制作用帮助维持外周耐受性。然而,自体免疫是否与LNSCs的致敏功能缺陷有关尚不清楚,对LNSCs在人体内的特征性研究也不多见。我们假设1糖尿病患者和NOD小鼠胰腺淋巴结T细胞反应异常可能与LNSC功能改变有关。

我们使用流式细胞术分析来自1糖尿病NOD小鼠的plnLNSC分布和表型。评估了来自人类供体的LNSCs的不同亚群中与耐受性相关的基因的表达,以及在自身免疫调节因子(AIRE)+细胞富集的树突状细胞群中(鉴定为HLA-DRhigh CD45low)的表达。

研究发现,在1糖尿病NOD小鼠中,不同LNSC亚群的相对频率均发生改变,而在人类1型糖尿病中,MHC II类和程序性死亡配体1 (PD-L1)表达均上调。耐受相关基因在小鼠和人类LNSCs的稳态表达谱相似,但在人类1型糖尿病中普遍上调,而与此同时,许多此类基因在富含air的树突状细胞群中下调。

研究显示,在1型糖尿病患者中,LNSCs发生了显著改变,但令人惊讶的是,它们显示出增强的致耐受性表型以及增加的抗原呈递潜能,这可能表明试图抵消树突状细胞相关的致耐受性缺陷。 因此,LNSC可以构成替代性治疗靶标,在其中传递抗原以帮助重新建立耐受性并预防或治疗1型糖尿病。
