概括

血化陶 (p-tau) 种在神经内核包容性疾病 (NIID) 和其症状前阶段 (NIID前) 中升高. 这些生物标志物显示出诊断NIID的潜力,将其与健康对照区分开来.

科学领域:

神经科学是一个神经科学.
生物标志物发现发现
神经退行性疾病神经退行性疾病

背景情况:

神经内核包容性疾病 (NIID) 是一种神经退行性疾病,与NOTCH2NLC中的GGC重复扩张有关,通常会导致认知障碍.
关于NIID和症状前NIID (preNIID) 的生物标志物改变的研究有限.
NIID和阿尔茨海默病 (AD) 之间的临床相似性需要在NIID和NIID前探索血生物标志物.

研究的目的:

调查NIID和NIID前患者的血生物标志物变化.
评估血生物标志物的诊断潜力,包括化 (p-tau) 种,以区分NIID和NIID前的健康对照和AD.
探索NIID中生物标志物水平和临床/成像发现之间的关系.

主要方法:

在NIID患者,AD患者,NIID前个体和健康对照组中分析了血生物标志物 (Aβ40,Aβ42,NfL,α-synuclein,p-tau181,p-tau217,p-tau231,GFAP).
使用神经心理测试,MRI,Aβ-PET和tau-PET进行全面的患者评估.
进行了统计分析,以评估生物标志物水平及其相关性.

主要成果:

与健康对照人群相比,NIID患者观察到高水平的p-tau物种 (p-tau217,p-tau231,p-tau181) 和GFAP.
在NIID前的个体也显示了增加的p-tau物种和GFAP.
血p-tau217显示了NIID/preNIID和健康对照之间的良好的区分能力,但无法区分NIID和AD.
通过TAU-PET,在NIID的叶和极中通过TAU-PET识别出明显的TAU沉积模式,独立于Aβ病理.

结论:

血p-tau水平的显著变化和在大脑中观察到的tau沉积表明NIID中涉及tau病理.
在NIID前和NIID中的高血p-tau物种表明它们作为NIID的诊断生物标志物具有潜在的实用性.

关键词:

在GFAPAP中,GFAP是最重要的.神经元内核包容性疾病是神经元内核包容性疾病.血生物标志物血生物标志物没有症状的NIID.这就是P-tau.tau-PET是一种PET.

Neural Regulation

Neural Regulation

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

Amyloid Fibrils

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,...
