Thyroid-associated ophthalmopathy (TAO) is the most common orbital disease in adults, potentially leading to disfigurement and visual impairment. However, the causes of TAO are not fully understood. IL-35B cells are a newly identified regulatory B cells (Bregs) in maintaining immune balance in various autoimmune diseases. Yet, the influence of IL-35Bregs in TAO remains unexplored.
This study enrolled 36 healthy individuals and 14 TAO patients. We isolated peripheral blood mononuclear cells and stimulated them with IL-35 and CpG for 48 h. Flow cytometry was used to measure the percentages of IL-35Bregs.
The percentage of circulating IL-35Bregs was higher in TAO patients, and this increase correlated positively with disease activity. IL-35 significantly increased the generation of IL-35Bregs in healthy individuals. However, B cells from TAO patients exhibited potential impairment in transitioning into IL-35Breg phenotype under IL-35 stimulation.
Our results suggest a potential role of IL-35Bregs in the development of TAO, opening new avenues for understanding disease mechanisms and developing therapeutic approaches.
甲状腺相关眼病(TAO)是成人中最常见的眼眶疾病,可能导致容貌受损和视力障碍。然而,TAO 的病因尚未完全明了。IL-35B 细胞是一种新发现的调节性 B 细胞(Bregs),在各种自身免疫性疾病中维持免疫平衡。然而,IL-35Bregs 在 TAO 中的影响仍未被探索。
本研究纳入 36 名健康个体和 14 名 TAO 患者。我们分离外周血单核细胞,并用 IL-35 和 CpG 刺激 48 小时。流式细胞术用于测量 IL-35Bregs 的百分比。
TAO 患者循环中 IL-35Bregs 的百分比较高,且这种增加与疾病活动度呈正相关。IL-35 可显著增加健康个体中 IL-35Bregs 的生成。然而,TAO 患者的 B 细胞在 IL-35 刺激下向 IL-35Breg 表型转化的能力存在潜在缺陷。
我们的结果提示 IL-35Bregs 在 TAO 的发生发展中可能具有一定作用,为理解疾病机制和开发治疗方法开辟了新的途径。
