科学领域:
- 心血管医学 心血管医学
- 生物标志物 生物标志物
- 神经退行性疾病研究研究
背景情况:
- 循环中的粉样蛋白-β 1-40 (Ab40) 呈现出促动脉动脉的特性.
- Ab40是动脉样硬化心血管疾病 (ASCVD) 的潜在生物标志物.
- 关于Ab40与动脉样硬化斑块形态和组成的关联存在有限的数据.
研究的目的:

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,...
