PROJECT SUMMARY- BIOMARKER CORE (CORE G) The Biomarker Core (BMC) of the Wisconsin Alzheimer's Disease Research Center (ADRC) represents the capability and infrastructure for peering into the brain in vivo to obtain biological markers of Alzheimer's disease (AD) and related disorders and non-disease-specific qualities characterizing brain health and resilience. Since the pre-clinical time frame of AD is a major emphasis of the ADRC, and since it is increasingly understood that AD pathology occurs well before its symptoms, the charge of this core is to provide the necessary capabilities, tools, and infrastructure to investigators to characterize as accurately as possible the early in-vivo changes of AD, effect of risk and resilience factors, and effect of prevention strategies on relevant biomarkers. The core will focus on collecting, quality checking, and curating several types of AD-relevant biomarkers including a) markers indicative of AD - defined by amyloid plaques and neurofibrillary tangles, and ascertainable by molecular PET imaging or cerebrospinal fluid (CSF) assays; b) markers of cerebrovascular diseases - the second most common etiology (or etiologies) of cognitive decline and ascertainable by new MRI methods; c) markers of other neurodegenerative diseases as they become available via CSF or PET; and d) markers of general brain health including synaptic density, neuronal injury, atrophy, connectivity, inflammation, and blood flow that are possible through PET, MRI and CSF modalities. To meet these goals, we will accomplish the following aims: Aim 1: Obtain biological markers of AD's hallmark neuropathological features - amyloid plaques and neurofibrillary tangles with CSF and/or molecular PET imaging. Aim 2: Collect biomarkers of concomitant features, such as vascular disease, inflammation, and neuronal death. Aim 3: Develop method for interpreting biomarker readouts, particularly for Amyloid (A), tau (T) and neurodegeneration (N). Aim 4: Support ADRC investigators with infrastructure and analytic support. Aim 5: Share images, fluid, and derived data with the National Alzheimer's Coordinating Center (NACC), local investigators, and other qualified investigators throughout the world. Aim 6: Expand the Center's biomarker capability, including a) adopting new methods and modalities in this fast-changing field, and b) for harmonizing previously collected data or multi-site data with current or future collection methods. The BMC will work interactively with the other ADRC cores to serve the needs of the ADRC investigators as efficiently as possible and deliver high quality data to NACC and other users so we, as a field, can come to answers faster in detecting and intervening effectively in AD.

项目摘要 - 生物标志物核心 (CORE G) 威斯康星州阿尔茨海默病研究中心 (ADRC) 的生物标志物核心 (BMC) 代表 体内观察大脑以获得阿尔茨海默氏症生物标记的能力和基础设施 疾病（AD）和相关疾病以及表征大脑健康和非疾病特异性的品质 弹力。由于 AD 的临床前时间范围是 ADRC 的重点，并且由于它越来越多 了解 AD 病理发生早于其症状，该核心的职责是提供 为调查人员提供必要的能力、工具和基础设施，以尽可能准确地描述事件的特征 AD 的早期体内变化、风险和恢复因素的影响以及预防策略对相关因素的影响 生物标志物。核心将侧重于收集、质量检查和策划几种类型的广告相关内容 生物标志物包括a)指示AD的标志物——由淀粉样蛋白斑和神经原纤维缠结定义，以及 可通过分子 PET 成像或脑脊液 (CSF) 检测确定； b) 脑血管标志物 疾病 - 认知能力下降的第二个最常见病因（或多个病因），可通过新的 MRI 确定 方法; c) 通过 CSF 或 PET 获得的其他神经退行性疾病的标志物；和 d) 一般大脑健康的标志物，包括突触密度、神经元损伤、萎缩、连通性、炎症、 以及通过 PET、MRI 和 CSF 方式可能实现的血流。为了实现这些目标，我们将 实现以下目标： 目标 1：获得 AD 标志性神经病理学特征的生物标记 - 通过 CSF 和/或分子 PET 成像观察淀粉样斑块和神经原纤维缠结。目标 2：收集生物标志物 伴随特征，如血管疾病、炎症和神经元死亡。目标 3：开发方法 用于解释生物标志物读数，特别是淀粉样蛋白 (A)、tau (T) 和神经退行性变 (N)。目标 4： 为 ADRC 调查人员提供基础设施和分析支持。目标 5：共享图像、流体和衍生图像 国家阿尔茨海默病协调中心 (NACC)、当地研究人员和其他合格人员的数据 世界各地的调查人员。目标 6：扩大中心的生物标志物能力，包括 a) 采用新的 在这个快速变化的领域中的方法和模式，以及 b) 协调以前收集的数据或多地点的数据 当前或未来收集方法的数据。 BMC 将与其他 ADRC 内核交互工作 尽可能高效地满足 ADRC 研究人员的需求，并向 NACC 提供高质量的数据 以便我们作为一个领域能够更快地找到答案，从而有效地检测和干预 AD。
