含有caspase招募域 (ASC) 的亡相关的斑状蛋白质显示,作为70岁以上个体早期认知衰退检测的血生物标志物具有前途. 在那些从正常认知转变为受损的人群中观察到高的ASC水平.
科学领域:
- 神经科学是一个神经科学.
- 生物标志物发现发现
- 老年学是指老年学的学科.
背景情况:
- 痴呆症在全球影响着5700万人,预计到2040年发病率将翻一番,这凸显了对早期诊断工具的迫切需要.
- 在不可逆转的脑退化发生之前,早期发现认知障碍对于及时干预至关重要.
研究的目的:
- 研究血生物标志物的潜力,包括ASC,NfL,GFAP和Aβ42/40,用于早期检测老年人认知能力下降.
- 确定可靠的生物标志物,可以区分认知正常,过渡和认知障碍状态.
主要方法:
- 在基线时从老年人收集血样本,并分析ASC,NfL,GFAP和Aβ42/40.
- 根据两次年度评估,参与者被分为认知正常 (NN),认知正常然后受损 (NI) 和认知受损 (II) 组.
- 使用统计分析,包括曲线下的面积 (AUC),来评估生物标志物的性能.
主要成果:
- 与亡相关的斑状蛋白含有酶招募域 (ASC) 在NI组的血中显著升高,与NN和II组相比.
- 粉样β 42 (Aβ42) 在NI和II组的血中相对于NN组相对增加.
- 在70岁以上的个人中,ASC在区分NN和NI组时显示AUC为0.81,表明具有强大的诊断潜力.
结论:
- ASC是一种有前途的血生物标志物,可用于早期检测认知衰退,特别是在70岁以上的个体中.
- 升高的ASC水平可能会在显著的临床表现之前表明认知障碍的早期阶段.
- 需要进一步的研究来验证ASC作为痴呆症的常规诊断工具.

Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
Antigens Involved in Adaptive Immunity
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
