概括

化在T181 (pTau-T181) 的度在肌缩侧面硬化症 (ALS) 中升高,可以作为生物标志物. 较高的pTau-T181水平与更快的ALS进展相关,这表明预后潜力.

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:

肌缩侧面硬化症 (ALS) 缺乏可靠的生物标志物.
微管相关蛋白质tau (tau) 水平在ALS患者的血和脑脊液 (CSF) 中发生变化.
以前的研究表明,脑脊髓中的增加与较快的ALS进展相关,而T181 (pTau-T181) 化与化的比率下降.

研究的目的:

与健康对照组 (HC) 相比,研究ALS患者的血pTau-T181和总tau水平.
评估血陶氏标志物与ALS疾病进展之间的相关性.
评估血pTau-T181作为潜在的ALS诊断或预后生物标志物的实用性.

主要方法:

来自ALS患者和HC的血样本使用Quanterix Simoa和Meso Scale Discovery (MSD) 试验分析了tau和pTau-T181.
进行了统计分析,以比较不同组的标志物水平,并将其与疾病进展相关联.

主要成果:

与HC相比,Quanterix Simoa和MSD测定均显示ALS患者的血pTau-T181水平和pTau-T181:tau比率增加.
较高的pTau-T181基线水平和pTau-T181:tau比率与更快的ALS进展相关.
血总含量在两项测试中显示出不同的趋势:在MSD上增加,在Quanterix Simoa下降.

结论:

在患有ALS的人群中,血pTau-T181水平升高.
血pTau-T181显示出作为ALS的诊断和预后生物标志物的潜力.
需要进一步的研究,以充分阐明血pTau-T181在ALS中的作用.

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,...

Phosphorylation

Phosphorylation

The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...
