Core B: Patient enrollment, specimen and data management, and biostatistics. This core supports Projects 1 and 2 in four ways. First, the core is responsible for enrolling patients and collecting clinical information that is needed for Projects 1 and 2. Patients are categorized according to the presence of graft- versus-host disease (GVHD) activity and immunosuppressive treatment. This information is obtained primarily by abstracting medical records from providers at the Seattle Cancer Care Alliance and from referring physicians. Second, the core is responsible for procuring blood samples from selected patients who have outcomes that are informative for the development of tolerance after hematopoietic cell transplantation (HCT). For example, samples are routinely obtained from patients when they leave Seattle at approximately 3 months after HCT and when they return for evaluation at 1 year after HCT. In addition, a concerted effort is made to collect blood samples before the onset of immunosuppressive treatment in patients who develop chronic GVHD. Blood samples are also collected from patients before and after infusion of donor lymphocytes for treatment of recurrent malignancy following HCT. In these patients, blood samples are also obtained before immunosuppressive medications are given to treat any GVHD that might occur after donor lymphocyte infusion. These samples are likely to be particularly informative, since donor lymphocyte infusions are used only in patients who have no GVHD after immunosuppressive medications have been withdrawn. In these patients, immune reactions can be monitored with no potential interference from the effects of immunosuppressive medications. Third, the core is responsible for processing blood samples, enumerating cells that express CDS, CD4, CDS, CD25, CD127 and HLA-DR, and freezing samples for future use in Projects 1 and 2. Fourth, the core provides support for data management and biostatistical analysis of results from Projects 1 and 2. RELEVANCE (See instructions): Immune reactions of donor cells against the recipient can cause complications when blood or marrow transplantation is used to treat leukemia and other diseases. The biological mechanisms that control these harmful immune reactions are not well understood. This core strengthens the overall program by providing investigators in Projects 1 and 2 with the clinical information and blood specimens needed for research studies that will help to identify the mechanisms that control these harmful immune reactions.

核心B：患者入学，标本和数据管理以及生物统计学。此核心支持 项目1和2分四种方式。首先，核心负责招募患者并收集临床 项目1和2所需的信息。根据移植物的存在对患者进行分类 与宿主病（GVHD）活性和免疫抑制治疗。获得此信息 主要是通过从西雅图癌症护理联盟提供者的医疗记录和 参考医生。其次，核心负责从选定患者那里采购血液样本 谁具有造血细胞后耐受性发展的结果 移植（HCT）。例如，样本是从患者离开西雅图时通常从患者那里获得的 HCT后约3个月，当他们在HCT后1年返回评估时。另外， 在免疫抑制治疗发作之前，要采取协同的努力来收集血液样本 发展慢性GVHD的患者。还从患者之前和之后收集血液样本 输注供体淋巴细胞，用于治疗HCT后复发性恶性肿瘤。在这些患者中，血液 在给予免疫抑制药物之前，还可以获得样品，以治疗任何可能的GVHD 在供体淋巴细胞输注后发生。这些样本可能特别有用，因为捐助者 淋巴细胞输注仅用于免疫抑制药物后没有GVHD的患者 已撤回。在这些患者中，可以监测免疫反应，没有潜在干扰 免疫抑制药物的作用。第三，核心负责处理血液 样品，表达CD，CD4，CD，CD25，CD127和HLA-DR的样品，冻结 在项目1和2的未来使用的样本。第四，核心为数据管理提供了支持， 项目1和2的结果分析。 相关性（请参阅说明）： 供体细胞对受体的免疫反应会在血液或骨髓时引起并发症 移植用于治疗白血病和其他疾病。控制这些的生物学机制 有害的免疫反应尚不清楚。该核心通过提供 项目1和2的研究人员，以及研究所需的临床信息和血液标本 将有助于确定控制这些有害免疫反应的机制的研究。
