Combining HLA-DQ-gluten tetramers with mass cytometry and RNA sequencing analysis, we find that gluten-specific CD4 T cells in the blood and intestines of patients with celiac disease display a surprisingly rare phenotype. Cells with this phenotype are also elevated in patients with systemic sclerosis and systemic lupus erythematosus, suggesting a way to characterize CD4 T cells specific for disease-driving antigens in multiple autoimmune conditions.
通过将 HLA-DQ- 谷蛋白四聚体与质谱流式细胞术和 RNA 测序分析相结合,我们发现乳糜泻患者血液和肠道中的 gluten 特异性 CD4 T 细胞表现出一种令人惊讶的罕见表型。具有这种表型的细胞在硬皮病和系统性红斑狼疮患者中也升高,提示了一种在多种自身免疫性疾病中鉴定针对疾病驱动抗原的 CD4 T 细胞的方法。
