项目摘要

PROJECT SUMMARY/ ABSTRACT Cigarette smoking is the greatest known single risk factor for the development of lung disease, being a dominant risk for the development of both emphysema and idiopathic pulmonary fibrosis. We have assembled a team of investigators who have worked synergistically to better understand the mechanism(s) by which cigarette smoke can induce either lung fibrosis or emphysema. Our team members are leaders in the field of COPD and IPF who are most committed to better understand the mechanism(s) by which cigarette smoke can induce either fibrotic or emphysematous phenotype in the lung. During the previous years of funding support by P01 HL114501 grant entitled “Distinct and Overlapping Pathways of Fibrosis and Emphysema in Cigarette Smokers”, we have integrated the expertise of investigators from the COPD and IPF communities, spanning basic, translational and clinical researchers, to come together to tackle this important challenge. This synergistic integration among the projects and cores have been impactful and will continue to be greater than the sum of each of its component parts. We employ both Ureductionist and mechanisticU approaches by utilizing cell culture and animal models (Project 1 and Project 2), and UdiscoveryU approaches using high throughput profiling (genomics, epigenetics) methods in human lung tissues and cells (Project 3) to discover new pathway(s) mediating the fibrotic and emphysema phenotypes in cigarette smoker. Hence, a PPG mechanism has been not only critical but absolutely necessary to best address the main objective of this fundamental question at hand: How can we better understand the mechanism(s) by which cigarette smoke mediates fibrotic or emphysematous phenotype in the lung? We will attempt to reach our goals by approaches described in the following Uprojects and cores: Projects: 1) Mitochondrial and Metabolic Dysfunction in COPD and IPF 2) Differential roles of Chi3l1 and its Receptors in Pulmonary Fibrosis and COPD 3) Integrating Omics, Networks, and Functional Studies in COPD and IPF Cores: A) Administrative Core B) Respiratory Computational Discovery Core C) Clinical Biorepository Core D) Molecular Characterization Core

项目摘要/摘要吸烟是肺部疾病发展的最大的单一危险因素肺气肿和特发性肺纤维化发展的主要风险。我们有组建了一个调查人员团队，他们协同工作以更好地了解机制香烟可以诱导肺纤维化或肺气肿。我们的团队成员是领导者最致力于更好地了解的COPD和IPF领域香烟烟雾可以在肺中诱导纤维化或过滤表型。在上一个 P01 HL114501授予的多年资金支持，标题为“纤维化的独特而重叠的途径和吸烟者中的肺气肿”，我们整合了COPD的调查人员的专业知识跨越基本，翻译和临床研究人员的IPF社区，共同解决这个问题重要的挑战。项目和核心之间的协同融合具有影响力，将会继续大于其每个组件部分的总和。我们雇用了培训者和通过使用细胞培养和动物模型（项目1和项目2）和Udiscoveryu进行机械方法方法使用高吞吐量分析（基因组学，表观遗传学）方法的方法细胞（项目3）发现介导香烟中纤维化和肺气肿表型的新途径吸烟者。因此，PPG机制不仅至关重要，而且绝对必要以最佳解决当前这个基本问题的主要目标：我们如何更好地了解哪种香烟介导肺中的纤维化或过滤表型？我们将尝试达到我们的目标是通过以下骚乱和核心中描述的方法：项目： 1）COPD和IPF中的线粒体和代谢功能障碍 2）CHI3L1及其受体在肺纤维化和COPD中的差异作用 3）在COPD和IPF中整合OMIC，网络和功能研究内核： a）行政核心 b）呼吸计算发现核心 c）临床生物座核 d）分子表征核心
