The Clinical Transplant Center Core will be comprised of 10 major academic transplant centers in the United States doing approximately 1360 adult kidney transplants per year in total. Its activities will be integrated with the three Scientific Projects through the Clinical Database, the Program Project website, yearly scientific meetings and active interim interactions between the 10 Clinical Investigators and the Principal Investigators. Our focused objectives for this Core are to provide the Projects with the requisite patient materials and correlating clinical data to test the hypotheses that: 1) gene expression and proteomic signatures in PBL and kidney transplant biopsies can be identified that correlate with biopsy-proven acute rejection and chronic allograft nephropathy, 2) gene and protein expression profiles will provide insights into the molecular pathways involved in both the host immune response and the donor organ's response to transplantation, 3) the adequacy of immunosuppression as defined by the absence of rejection-related gene and protein expression can be determined at any given time by gene and protein expression profiles, and 4) targeted SNP genotyping and candidate gene sequence studies will identify connections between the genetics of the donor and the recipients that correlate with transplant events and outcomes as well as with gene and protein expression signatures. Arching over all these hypotheses, we propose to examine the possibility that race (Caucasian, African American and Hispanic) and/or sex will genetically influence at least a subset of genes and proteins expressed post transplant and correlate with clinical outcomes. A critical point is that the correct clinical designations of the patient subgroups and successful completion of enrollment and specimen acquisitions, the two primary tasks for this Core, will determine the potential of success for all the scientists in the entire Program Project.

临床移植中心核心将由10个主要的学术移植中心组成 美国每年总共进行大约1360次成人肾脏移植。它的活动 将通过临床数据库与三个科学项目集成 项目网站，年度科学会议和10个临床之间的主动临时互动 调查人员和主要研究人员。我们针对该核心的目标是提供 具有必要的患者材料并将临床数据相关的项目，以测试以下假设： 1）PBL和肾脏移植活检中的基因表达和蛋白质组学特征可以是 鉴定出与活检证实的急性排斥和慢性同种异体肾病相关，2） 基因和蛋白质表达谱将提供有关涉及的分子途径的见解 宿主免疫反应和供体器官对移植的反应，3）足够 由缺乏与排斥相关的基因和蛋白质表达所定义的免疫抑制 可以通过基因和蛋白质表达谱在任何给定时间确定，4）靶向SNP 基因分型和候选基因序列研究将确定遗传学之间的联系 与移植事件和结果以及基因相关的供体和接受者 和蛋白质表达特征。对所有这些假设进行拱门，我们建议检查 种族（高加索人，非裔美国人和西班牙裔）和/或性别的可能性会从遗传上 影响至少一部分基因和蛋白质表达移植后表达并与临床相关 结果。一个关键点是，患者亚组的正确临床名称和 成功完成注册和标本获取，这是该核心的两个主要任务， 将确定整个计划项目中所有科学家的成功潜力。
