A&R:两种单克隆ACPA以PAD4依赖方式联合诱导小鼠腱鞘炎、疼痛和骨丢失

2022-08-07 紫菀款冬 MedSci原创

研究抗瓜氨酸蛋白抗体(ACPA)除了疼痛和骨丢失之外是否还能诱发腱鞘炎(RA的早期症状),以及这些症状是否依赖于肽基精氨酸脱氨酶(PAD4)。

目的:抗瓜氨酸蛋白抗体(ACPA)在血液循环中的出现是类风湿关节炎(RA)的主要危险因素。患者来源的ACPA已显示在小鼠中诱导疼痛和骨侵蚀,表明其在RA的致病性中起积极作用

该团队旨在研究ACPA除了疼痛和骨丢失之外是否还能诱发腱鞘炎(RA的早期症状),以及这些症状是否依赖于肽基精氨酸脱氨酶(PAD4)

方法:将RA患者浆细胞产生的单克隆ACPA转移至野生型和PAD4缺陷小鼠。对疼痛样行为和宏观炎症进行为期4周的监测,然后使用磁共振成像(MRI)分析踝关节腱鞘炎,并使用X射线显微镜分析胫骨的骨微结构。在脱钙的踝关节切片中分析腱鞘的微观变化。

结果:两种单克隆ACPA(1325:04C03和1325:01B09)的组合在小鼠中诱导了持久的疼痛样行为和小梁骨丢失。肉眼未观察到滑膜炎,但通过MRI在注射ACPA的小鼠中检测到滑膜炎。

对关节的显微镜分析显示,ACPA治疗组表现为细胞增生和腱鞘增大。在PAD4缺陷小鼠中,ACPA对疼痛样行为、腱鞘炎和骨丢失的影响显著降低

结论:单克隆ACPA除了通过依赖于PAD4介导的瓜氨酸化的机制引起疼痛和骨丢失外,还可诱导腱鞘炎
