概括

血酸化-tau217 (p-tau217) 在尼曼-皮克病C型中升高,与疾病进展相关. 这一发现表明p-tau217可能是这种罕见的神经退行性疾病的宝贵生物标志物.

科学领域:

神经科学是一个神经科学.
生物化学生物化学
遗传学是一个遗传学.

背景情况:

尼曼-皮克病C型 (NPC) 和阿尔茨海默病 (AD) 是不同的神经退行性疾病.
无论是NPC还是AD,都具有共同的神经纤维状结病理,表明潜在的重叠生物机制.

研究的目的:

为了研究NPC患者的酸化tau217 (p-tau217) 血水平.
评估血p-tau217与NPC疾病进展和严重程度的相关性.
为了比较NPC和阿尔茨海默病不同亚型之间的血p-tau217水平.

主要方法:

一项多中心研究测量了对照组,NPC患者和AD患者的血p-tau217 (A+T-和A+T+).
在NPC中对p-tau217的纵向评估,与年度严重性增量得分和lysotracker测量相关.
横截面分析比较所有组的p-tau217水平.

主要成果:

与对照组相比,血p-tau217的NPC显著增加.
血p-tau217水平与NPC发病时的年龄相反相关.
血p-tau217与NPC中的疾病进展 (年度严重性增加得分) 和溶酶体扩大具有积极的相关性.
在A+T-AD中的血p-tau217水平与NPC相似,而A+T+AD显示的水平高于NPC.

结论:

在NPC中观察到血p-tau217的升高,NPC是一种具有孤立tau病理的疾病.
血p-tau217显示与NPC疾病进展和严重程度的关联.
血p-tau217是一种潜在的,有前途的生物标志物,用于监测C型尼曼-皮克病.

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
