PROJECT 3 ABSTRACT Medications are an important exposure in the life course epidemiology framework that ties the Adult Changes in Thought (ACT) U19 Program together. Medications for chronic conditions are taken over several years, often beginning in mid-life, and chronic regimens achieve consistent blood levels, so toxic or protective brain effects of medication exposures are plausible. The Adult Changes in Thought (ACT) study has served as an incredible resource for cutting-edge dementia pharmacoepidemiology research for over 20 years. We take a multifaceted approach to examine links between common drugs and brain health by using an array of brain-related measures in the same cohort to deepen our understanding about these relationships and mechanisms. A considerable methodologic issue inherent in pharmocoepidemiology research is confounding by indication, where the condition for which a drug is prescribed is associated with dementia rather than the drug itself. In this Project, we take an innovative and translational approach to complement our existing pharmacoepidemology methods by deploying molecular assays that will directly address confounding by indication bias with a cell-based model using human induced pluripotent stem cell (hiPSC)-derived neurons (hiPSC-Ns) from ACT participants. The following Aims will be accomplished by working directly with all Project Cores. Aim 1: Deploy a human stem cell- based molecular assay to directly test mechanisms of neurotoxicity from anticholinergics (AChs) and address confounding by indication. We will deploy assays that measure four cellular outcomes: AD pathological molecules, Ab and pTau; neurotoxicity; and neuronal function. Aim 2: To determine comparative associations of antihypertensives (AHTs) with dementia and AD (2A), neuropathology (2B), and neuroimaging outcomes (2C), and test mechanisms of neuroprotection (2D). We will test the hypotheses that after controlling for their effects on blood pressure, exposure to Ang-II↑ drugs compared with Ang-II↓ drugs is associated with lower risk of dementia and AD, neuropathology and neuroimaging outcomes. We will test the hypothesis that Ang-II↑ drugs will have positive effects on cellular outcomes (i.e: Aβ and pTau, neurotoxicity and neuronal function) compared with an Ang-II↓ drug using the group of hiPSC-derived neurons developed in Aim 1.

项目3摘要 药物是生命过程流行病学框架中的一个重要暴露，它将成人变化与 一起思考（ACT）U19节目。慢性病的药物治疗通常需要几年的时间， 从中年开始，长期方案达到一致的血液水平，因此有毒或保护大脑的作用 是合理的成人思想变化（ACT）研究是一项令人难以置信的研究。 超过20年的尖端痴呆症药物流行病学研究资源。我们采取多方面的 通过使用一系列与大脑相关的措施来检查常见药物与大脑健康之间联系的方法 以加深我们对这些关系和机制的理解。相当 药物流行病学研究中固有的方法学问题受到适应症的混淆， 开药的条件与痴呆症有关，而不是药物本身。在本项目中， 我们采取创新和转化的方法来补充我们现有的药物药理学方法 通过部署分子测定，直接解决基于细胞模型的适应症偏倚的混淆 使用来自ACT参与者的人诱导多能干细胞（hiPSC）衍生的神经元（hiPSC-Ns）。的 以下目标将通过与所有项目核心直接合作来实现。目标1：部署人类干细胞- 基于分子测定，直接测试抗胆碱能药物（ACh）的神经毒性机制，并解决 因适应症而混淆。我们将部署测量四种细胞结果的测定： 分子，Ab和pTau;神经毒性;和神经元功能。目标2：确定以下方面的比较关联： 抗高血压药（AHT）与痴呆和AD（2A），神经病理学（2B）和神经影像学结局（2C）， 和测试神经保护机制（2D）。我们将检验假设，在控制了它们的影响后， 在血压方面，与Ang-II ↓药物相比，Ang-II↑药物暴露与以下风险降低相关： 痴呆和AD，神经病理学和神经影像学结果。我们将检验Ang-II↑药物 将对细胞结果（即：Aβ和pTau，神经毒性和神经元功能）产生积极影响， 使用Aim 1中开发的hiPSC衍生的神经元组与Ang-II↓药物。 我们的项目具有重要意义
