概括
大脑脊髓液α-synuclein播种活动 (SSA) 可以预测风险人群中的中央Lewy体疾病 (LBD). 升高的初始SSA水平表明患LBD的可能性更高.
科学领域:
- 神经科学是一个神经科学.
- 生物标志物发现发现
- 神经学 神经学
背景情况:
- 大脑脊髓液 (CSF) 的α-synuclein播种活动 (SSA) 是中枢Lewy体疾病 (LBD) 的潜在生物标志物.
- 预测处于危险人群中的LBD对于早期干预至关重要.
研究的目的:
- 为了前性地评估CSF SSA在患有中央LBD风险的个体中的预测价值.
- 评估基线CSF SSA水平与LBD后续发展之间的关联.
主要方法:
- 一项前性的纵向研究招募了具有≥3个LBD风险因素的参与者.
- 收集了CSF样本,并使用种子放大试验测量了SSA.
- 参与者进行了长达7.5年的随访,以确定LBD诊断.
主要成果:
- 在11名具有高平均SSA曲线下面面积 (AUCs) (>500,000单位) 的受试者中,7人 (64%) 患有中央LBD.
- 在20名受试者中,只有1名 (5%) 的AUC低于截止值,患有LBD (P=0.0011).
- 88%患有LBD (LBD+) 的参与者最初的SSA AUCs升高.
结论:
- 增加的CSF SSA是中心LBD发展的重要预测因素.
- 较高的初始CSF SSA水平是发展为中央LBD的个体的特征.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

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,...
