用于诊断阿尔茨海默病(AD)和其他形式的痴呆症的生物标志物的鉴定和验证越来越重要。迄今为止,ELISA测量脑脊液(CSF)中的β-淀粉样蛋白(1-42)、总tau和磷酸化tau-181是诊断可能的AD的最先进和公认的方法,具有高特异性和灵敏度。然而,这是一个巨大的挑战,寻找新的生物标志物在脑脊液和血液中使用现代有效的方法,如微阵列和质谱,并优化样品的处理(如收集,运输,处理和储存),以及使用生物信息学的解释。似乎只有几种生物标志物的组合分析才能定义未来诊断AD的患者特异性特征。
The identification and validation of biomarkers for diagnosing Alzheimer's disease (AD) and other forms of dementia are increasingly important. To date, ELISA measurement of β-amyloid(1–42), total tau and phospho-tau-181 in cerebrospinal fluid (CSF) is the most advanced and accepted method to diagnose probable AD with high specificity and sensitivity. However, it is a great challenge to search for novel biomarkers in CSF and blood by using modern potent methods, such as microarrays and mass spectrometry, and to optimize the handling of samples (e.g. collection, transport, processing, and storage), as well as the interpretation using bioinformatics. It seems likely that only a combined analysis of several biomarkers will define a patient-specific signature to diagnose AD in the future.
