Summary Anti-atherogenic functions of HDL are likely due to its mediation of reverse cholesterol transport and to its anti-oxidative and anti-inflammatory effects. Mounting evidence supports the concept that HDL may become dysfunctional and that this contributes to the development of atherosclerosis. The goal of our research is to define the mechanisms for HDL dysfunction in diseases associated with significantly increased risk of atherosclerotic cardiovascular disease, including familial hypercholesterolemia, chronic kidney disease and rheumatoid arthritis. A major hypothesis of our proposal is that excessive inflammatory and oxidative burden impair HDL atheroprotective functions, including cholesterol efflux capacity and anti-inflammatory and anti- oxidative effects. Core B will be an integral part of the PPG by providing both analytical services for analysis and isolation of lipoproteins and in vitro assays of HDL function in macrophages. The goal of Specific Aim 1 is to provide isolation and analysis of lipoproteins, HDL subfractions, and apoproteins. The Lipoprotein and HDL Function Core (Core B) will assist investigators by isolating lipoproteins and apoproteins, including apoAI and apoAII, for functional studies and analyses of protein modifications. The goal of Specific Aim 2 is to provide assays for HDL functions, including the promotion of cholesterol efflux and efferocytosis in macrophages and the control of inflammation and oxidation. Core B provides a number of services to investigators that require unique instrumentation and methodologies and demand rigorous standardization procedures. It would be costly, inefficient, and cumbersome to establish these procedures in individual investigator laboratories. The consolidation of these services into the Core B laboratory provides investigators with efficient, high quality, low-cost analyses. Another objective of Core B is to provide education and training to investigators, fellows, and research technicians on the science and methods of lipoprotein preparation and studies of HDL function.

概括 HDL 的抗动脉粥样硬化功能可能是由于其介导反向胆固醇转运 及其抗氧化和抗炎作用。越来越多的证据支持这一概念 HDL 可能会变得功能失调，这有助于发展 动脉粥样硬化。我们研究的目标是确定 HDL 功能障碍的机制 与动脉粥样硬化性心血管疾病风险显着增加相关的疾病， 包括家族性高胆固醇血症、慢性肾病和类风湿性关节炎。一个专业 我们提议的假设是过度的炎症和氧化负担会损害 HDL 动脉粥样硬化保护功能，包括胆固醇流出能力以及抗炎和抗动脉粥样硬化功能 氧化作用。核心 B 将通过提供分析服务成为 PPG 的组成部分 用于脂蛋白的分析和分离以及巨噬细胞中 HDL 功能的体外测定。这 具体目标 1 的目标是提供脂蛋白、HDL 亚组分和 脱辅基蛋白。脂蛋白和 HDL 功能核心（核心 B）将通过分离来帮助研究人员 脂蛋白和脱辅基蛋白，包括 apoAI 和 apoAII，用于功能研究和分析 蛋白质修饰。 Specific Aim 2 的目标是提供 HDL 功能检测，包括 促进巨噬细胞中的胆固醇流出和胞吞作用以及控制 炎症和氧化。核心 B 为需要的调查人员提供多种服务 独特的仪器和方法，需要严格的标准化程序。它 在个人中建立这些程序将是昂贵、低效且繁琐的 研究人员实验室。将这些服务整合到核心 B 实验室可提供 研究人员进行高效、高质量、低成本的分析。 Core B 的另一个目标是 为调查人员、研究员和研究技术人员提供科学方面的教育和培训 脂蛋白的制备方法和HDL功能的研究。
