A cohort of 10 Hashimoto's encephalopathy (HE) patients, 33 patients with unrelated neurological symptoms, 12 Hashimoto's thyroiditis patients and 4 healthy adult donors was studied to explore the neurological targets of anti-thyroperoxidase (TPO) autoantibodies (aAb) in HE. High levels of anti-TPO aAb were only detected in HE group's cerebrospinal fluids. In immunofluorescence assays on monkey brain cerebellum sections, both HE patients' sera and anti-TPO monoclonal antibodies (mAb) were able to bind cerebellar cells expressing glial fibrillary acid protein. Normal human astrocytes from primary cultures also reacted with anti-TPO mAb. Specific astrocyte binding of anti-TPO aAb suggests a role of these aAb in the HE pathogenesis.
研究了一组10例桥本脑病(HE)患者、33例有无关神经症状的患者、12例桥本甲状腺炎患者和4名健康成年供者,以探索HE中抗甲状腺过氧化物酶(TPO)自身抗体(aAb)的神经学靶点。仅在HE组的脑脊液中检测到高水平的抗TPO aAb。在猴脑小脑切片的免疫荧光试验中,HE患者的血清和抗TPO单克隆抗体(mAb)均能与表达胶质纤维酸性蛋白的小脑细胞结合。原代培养的正常人星形胶质细胞也与抗TPO mAb发生反应。抗TPO aAb与星形胶质细胞的特异性结合表明这些aAb在HE发病机制中起作用。
