项目摘要

High-density lipoprotein (HDL) protects against atherosclerosis by removing excess cholesterol from arterial cells. HDL has also been proposed to function as an important Inhibitor of cellular inflammation and lipid oxidation in vivo. Moreover, inflammation has been proposed to convert HDL to a dysfunctional form that loses these cardioprotective effects and may even be pro-inflammatory. Two important pathways may Involve oxidative damage and changes in the relative balance of pro- and antioxidant proteins in HDL. During the first two years of the award, the PI has completed a highly structured career development plan to prepare him for transition to a fully independent investigator. During this time, he has published five first author papers in peer-reviewed journals, that have directly addressed the hypotheses raised in the original proposal. Importantly, he has obtained strong preliminary data in diabetic humans that the proposed mechanisms for generation of dysfunctional HDL are pathophysiologically relevant. In collaboration with translational investigators at the University of Washington, the PI has laid the groundwork for developing a research program centered on understanding the role of HDL in diabetic cardiovascular disease. Importantly, the proposed studies are completely Independent of that of his mentor. He also has accepted a faculty position with the University of Washington and the Department of Medicine has assigned him independent laboratory space and an office at the newly established Diabetes and Obesity Center of Excellence. During the next phase of the K99/R00 award, the PI will focus on two major goals: first, establishing a fully independent research program centered on diabetes and cardiovascular diseases. Second, obtaining NIH funding for his research studies. The long-term goal is to combat atherosclerosis by understanding the molecular mechanisms for generation of dysfunctional HDL in humans suffering from diabetes and other inflammatory conditions.

高密度脂蛋白（HDL）通过从动脉细胞中去除多余的胆固醇来预防动脉粥样硬化。还建议HDL充当体内细胞炎症和脂质氧化的重要抑制剂。此外，已经提出了炎症将HDL转换为失去这些心脏保护作用的功能失调的形式，甚至可能是促炎性的。两种重要的途径可能涉及HDL中促氧化和抗氧化剂蛋白的相对平衡的氧化损伤和变化。在该奖项的前两年中，PI完成了一项高度结构化的职业发展计划，以准备过渡到完全独立的调查员。在此期间，他在同行评审期刊上发表了五篇第一篇作者论文，这些论文直接解决了原始提案中提出的假设。重要的是，他在糖尿病性人类中获得了强大的初步数据，即产生功能障碍HDL的提议的机制在病理生理上是相关的。与华盛顿大学的转化调查员合作，PI为制定了一项研究计划奠定了基础，该研究计划的重点是了解HDL在糖尿病心血管疾病中的作用。重要的是，拟议的研究完全独立于他的导师。他还接受了华盛顿大学的教职员工职位，医学系已将他分配给他独立的实验室空间，并在新成立的糖尿病和肥胖卓越中心的办公室任职。在K99/R00奖的下一阶段，PI将重点关注两个主要目标：首先，建立一个以糖尿病和心血管疾病为中心的独立研究计划。其次，为他的研究获得NIH资金。长期的目标是通过了解患有糖尿病和其他炎症状况的人类产生功能失调的HDL的分子机制来对抗动脉粥样硬化。
