Case Proteomics Center for HIV/AIDS and Drug Abuse

描述（由申请人提供）：本P20申请提议建立HIV/AIDS和药物滥用案例蛋白质组学中心，旨在应用最先进的蛋白质组学和系统生物学工具来研究药物滥用背景下的HIV发病机制，并提供HIV感染、与其他病毒合并感染和药物滥用的重要生物标志物。在试验阶段，我们将开展三个相互关联的项目，旨在更好地了解对同时接触成瘾性药物的艾滋病毒感染者的免疫功能和活动的影响，以及重要的病毒辅助因子丙型肝炎（HCV）。在这些项目中，将直接检查上皮细胞或t细胞中的蛋白质组反应，并平行检查受影响患者的血浆读数。这些项目的一个主要成果将是开发可用于大规模人口研究的信息性生物标志物和方法，以进一步评估药物使用对艾滋病毒疾病的影响。该中心将由蛋白质组学案例中心主任Mark Chance博士领导，他是国际公认的蛋白质组学和系统生物学专家，与分子生物学和微生物学系主任、艾滋病研究案例中心（CFAR）联合主任Jonathan Karn博士合作，他是艾滋病毒/艾滋病分子生物学专家。这些试点项目是Case一个强大的多学科团队的工作，该团队结合了医学系、分子生物学与微生物学系、生物科学系（牙科学院）和CFAR在艾滋病毒/艾滋病方面的重要生物专业知识。这些研究人员已经收集了重要的分子生物学和蛋白质组学数据，在蛋白质组学和生物信息学核心服务的三个试点项目的背景下提供可测试的假设。这三个项目将在病例CFAR临床核心的合作下，招募合适的患者队列提供相关样本。然后，Core的蛋白质组学团队将对病例与相关对照人群进行蛋白质组表达分析，并向生物信息学团队提供具有统计意义的目标。该团队不仅将在要解决的生物学问题的背景下提供网络分析和途径鉴定，而且将蛋白质组学途径模型与已知的药物成瘾和艾滋病毒发病途径相关联，并将通过蛋白质组学和微阵列数据的组合分析推断新的子网络。

DESCRIPTION (provided by applicant): This P20 application proposes the creation of the Case Proteomics Center in HIV/AIDS & Drug Abuse, which is designed to apply state-of-the art proteomics and systems biology tools to investigate HIV pathogenesis in the context of drug abuse and provide significant biomarkers of HIV infection, co-infection with other viruses, and drug abuse. During the pilot phase, we will undertake three inter-related projects designed to provide a better understanding of the impact on immune function and activity in HIV-infected individuals who are also exposed to addictive drugs, and the important viral co-factor Hepatitis C (HCV). In each of these projects there will be a direct examination of the proteomic responses in epithelial or T-cells and parallel examination of plasma readouts from affected patients. A major outcome of these projects will be development of informative biomarkers and methods that can be used in large-scale population studies to further evaluate the impact of drug use on HIV disease. The Center will be directed by Dr Mark Chance, Director of the Case Center for Proteomics, and an internationally recognized expert in proteomics and system biology in collaboration with Dr Jonathan Karn, Chair of the Department of Molecular Biology & Microbiology and Co-Director of the Case Center for AIDS Research (CFAR), and an expert in HIV/AIDS molecular biology. The pilot projects are the work of a strong pre-existing multi-disciplinary team at Case that combines significant biological expertise in HIV/AIDS within the Department of Medicine, the Department of Molecular Biology & Microbiology, the Department of Biological Sciences (Dental School) and CFAR. These investigators have already assembled significant molecular biology and proteomics data to provide testable hypotheses within the context of three Pilot Projects served by a Proteomics and Bioinformatics Core. The three projects, with the cooperation of the clinical core of the Case CFAR, will recruit appropriate patient cohorts to provide relevant samples. The proteomics team in the Core will then conduct proteome expression analysis of cases versus relevant control populations, with statistically significant targets provided to the Bioinformatics team. This team will not only provide network analysis and pathway identification within the context of the biological questions to be addressed, but will correlate the proteomics pathway models with known pathways of drug addiction and HIV pathogenesis and will infer novel sub-networks by combined analysis of proteomics and microarray data.
