概括
野生类型的跨氨基粉症 (ATTRwt) 可以导致超过一半的患者感官神经病变. 需要进一步的研究来了解这种外周神经系统参与的原因.
科学领域:
- 神经学 神经学
- 遗传学 是一个遗传学.
- 病理学 病理学 病理学
背景情况:
- 晶氨基粉症 (ATTR) 是一种系统性疾病,涉及粉样纤维的积累,被分类为突变型 (ATTRv) 或野生型 (ATTRwt).
- ATTRwt通常会影响心脏和骨关节系统,但外围神经病变,包括手掌道综合征 (CTS),也可能发生.
- 与ATTRv相比,关于ATTRwt涉及周围神经系统 (PNS) 的信息有限.
研究的目的:
- 为了调查患有野生类型的跨氨酸氨基化症 (ATTRwt) 的患者中外周神经系统参与的患病率和特征.
主要方法:
- 对30名ATTRwt患者进行了神经检查和神经传导研究 (NCS).
- 对于已确诊的多神经病症患者,建议进行外围神经活检以检测粉样蛋白沉积物.
主要成果:
- 53%的患者没有下肢远端肌反射,70%的患者有CTS.
- 在60%的患者 (30例中18例) 中,NCS发现了感官多神经病变.
- 经过外围神经活检的四分之二的患者显示了刚果红-阳性粉样蛋白沉积物.
结论:
- 在超过一半的ATTRwt患者中存在感官神经病变,表明疾病的全身性质.
- 在ATTRwt中感官多神经病变的发病,特别是在患有并发病的老年人中,需要进一步调查.
- 神经组织中粉样蛋白的组织学确认支持ATTRwt和PNS参与之间的因果关系.

Amyloid Fibrils
11.6K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...
