UPI报道称一种新发现的血液检验方法或许有助于治疗阿尔茨海默症新治疗的开发。

According to research published Wednesday in the journal Alzheimer's & Dementia,

根据周三发表于《Alzheimer's & Dementia》上的一项研究，

scientists have found that the number of fatty molecules¹ found in blood may contribute to the build-up of the amyloid peptide in the brain.

科学家们发现血液中脂肪分子的数量或许促进了大脑淀粉样肽的形成。

Amyloid peptide then turns into toxic² plaques³ in the brain that damage nerve cells.

然后淀粉样肽转变成大脑中损害神经细胞的有毒斑块。

This can cause plaque⁴ build-up to begin many years before any symptoms of Alzheimer's show.

在阿尔茨海默症的任何症状出现之前，这可能会导致斑块开始聚集。
