Core F: Biomarker Project Summary Neurodegenerative diseases result from multifactorial processes that cause pleiotropic changes in the molecular networks that link a host of biological processes, leading to protein aggregation in the brain, and ultimately to the relentless decline in cognition that characterizes most age-related dementing illnesses. Neurodegenerative diseases, such as Alzheimer disease (AD), idiopathic Parkinson's disease (PD), and frontotemporal lobar degeneration (FTLD) occur by mechanisms in which common or rare variants associated with disease risk are directly inherited or arise sporadically. Human somatic and stem cell models have emerged as a powerful system for modeling the complexities of pathological gene expression, particularly in the early phase of disease, in the context of a non-neoplastic human genome. Further, human stem cells can be differentiated into individual cell types affected in disease, such as neurons, astrocytes, microglia, and oligodendrocytes, as well as 3D “mini-brain” organoids. To this end, we have established a biorepository of stem cell models of AD and related dementias. The collection includes more than 200 human fibroblasts from the Knight ADRC and the Dominantly Inherited Alzheimer Network (DIAN) and induced pluripotent stem cell (iPSC) lines from more than 30 individuals carrying mutations in APP, PSEN1, PSEN2, GRN, MAPT, and risk variants in MAPT, APOE, TREM2, RAB10 and PLD3. Our long-term goal is to develop a set of tools and biomarkers for AD and related dementias. To do this, we will continue to build a biorepository of human somatic and stem cell models. These cells will facilitate the study of basic disease mechanisms, allow for discovery of novel biomarkers, and facilitate drug discovery platforms. We will focus on cell collection that builds on three major areas of strength in the Knight ADRC: (1) contributions of diverse ethnic backgrounds to molecular and cellular biomarkers of AD; (2) genetic and molecular modifiers of age at onset in large families with a dense family history of late onset AD; and (3) comparison of the molecular and cellular biomarkers that are common and unique between autososomal dominant AD and sporadic, late onset AD. Finally, we will make available the human somatic and stem cell lines to the broader research community to revolutionize our understanding of AD and related dementias.

核心 F：生物标志物项目摘要 神经退行性疾病是由多因素过程引起的，这些过程会导致神经系统的多效性变化 连接一系列生物过程的分子网络，导致大脑中的蛋白质聚集，以及 最终导致认知能力持续下降，这是大多数与年龄相关的痴呆症的特征。 神经退行性疾病，例如阿尔茨海默病 (AD)、特发性帕金森病 (PD) 和 额颞叶变性 (FTLD) 的发生机制与常见或罕见变异相关 具有疾病风险的疾病是直接遗传的或散发的。人类体细胞和干细胞模型 成为一个强大的系统，用于模拟病理基因表达的复杂性，特别是在 在非肿瘤人类基因组的背景下，疾病的早期阶段。此外，人类干细胞可以 分化为受疾病影响的单个细胞类型，例如神经元、星形胶质细胞、小胶质细胞和 少突胶质细胞，以及 3D“迷你大脑”类器官。为此，我们建立了生物样本库 AD 和相关痴呆症的干细胞模型。该系列包括 200 多种人类成纤维细胞 Knight ADRC 和显性遗传性阿尔茨海默病网络 (DIAN) 以及诱导多能干细胞 (iPSC) 系来自 30 多个携带 APP、PSEN1、PSEN2、GRN、MAPT 和风险突变的个体 MAPT、APOE、TREM2、RAB10 和 PLD3 的变体。我们的长期目标是开发一套工具和 AD 和相关痴呆症的生物标志物。为此，我们将继续建立人类生物资源库 体细胞和干细胞模型。这些细胞将促进基本疾病机制的研究，允许 发现新型生物标志物，并促进药物发现平台。我们将重点关注细胞收集 建立在骑士 ADRC 的三个主要优势领域：(1) 不同种族背景对 AD 的分子和细胞生物标志物； (2) 大家庭中发病年龄的遗传和分子修饰因素 具有严重的迟发性 AD 家族史； (3) 分子和细胞生物标志物的比较 在常染色体显性 AD 和散发性迟发性 AD 之间是常见且独特的。最后，我们将制作 向更广泛的研究界提供人类体细胞和干细胞系，以彻底改变我们的研究 了解 AD 和相关痴呆症。
