This revised application for our new Program Project Grant brings together a group of investigators who are experts in the areas of molecular and cellular immunology and human and mouse genetics. We propose to study the role of single genes in the pathogenesis of X-linked Lymphoproliferative syndrome (XLP), Common variable immunodeficiency (CVID), Omenn syndrome and Severe Combined Immunodeficiencies (SCID) in an application, entitled: "Primary Immunodeficiencies Affecting Specific Stages of the Adaptive Immune Rresponse" Because of successful preliminary analyses of patient materials, exciting findings in genetically altered mice, this application seeks to define how mutations in the SH2D1A, SH2D1B/C, TACI, RAG-1/2, DNA Ligase IV or Cernunnos genes affect T and B cell development and T cell dependent and/or T cell-independent immunoglobulin responses. We will use our recently acquired insights into the causes of these diseases in the following four interlinked projects and an Administrative Core: Project #1 Role of the SAP (SH2D1A) gene in T cell-dependent antibody responses. Cox Terhorst, Beth Israel Deaconess Medical Center. Project #2 Role of in TACI mutations in Common Variable Immunodeficiency Raif Geha, Children's Hospital of Boston. Project #3 Gene knock-in models for Omenn syndrome and leaky SCID. Luigi Notarangelo, Children's Hospital of Boston. Project #4 Mouse Models of Severe Combined Immunodeficiencies. Fred Alt, Children's Hospital of Boston. Core A Administrative Core Cox Terhorst, Beth Israel Deaconess Medical Center. The outcomes of proposed studies should lead to better understanding of the complex and often alternate disease manifestations that are caused by mutations in a single gene. The results of these studies should suggest therapeutic strategies that can be applied to these PID patients and may unravel molecular and cellular mechanisms that are generally involved in immune dysregulation, autoimmunity and cancer.

我们的新计划项目补助金的修订申请汇集了一组研究人员，他们是 分子和细胞免疫学以及人类和小鼠遗传学领域的专家。我们建议 研究单基因在X连锁恶性增殖综合征（XLP）发病机制中的作用， 变异性免疫缺陷（CVID）、Omenn综合征和严重联合免疫缺陷（SCID）， 一项申请，题为： “影响适应性免疫反应特定阶段的原发性免疫缺陷” 由于对患者材料的初步分析成功，在转基因小鼠中的令人兴奋的发现， 本申请试图定义SH 2D 1A、SH 2D 1B/C、TACI、RAG-1/2、DNA连接酶IV 或Cernunnos基因影响T和B细胞发育以及T细胞依赖性和/或T细胞非依赖性 免疫球蛋白反应。我们将利用我们最近对这些疾病的原因的了解， 以下四个相互关联的项目和一个行政核心： 项目#1 SAP（SH 2D 1A）基因在T细胞依赖性抗体应答中的作用。 考克斯特霍斯特，贝斯以色列女执事医疗中心。 项目#2 TACI突变在常见变异型免疫缺陷中的作用 Raif Geha波士顿儿童医院 项目#3 Omenn综合征和渗漏性SCID的基因敲入模型。 路易吉·诺塔朗吉洛波士顿儿童医院 项目#4严重联合免疫缺陷的小鼠模型。 弗雷德·阿尔特波士顿儿童医院 核心A行政核心 考克斯特霍斯特，贝斯以色列女执事医疗中心。 拟议研究的结果应有助于更好地了解复杂和经常交替的 由单个基因突变引起的疾病表现。这些研究的结果应该 提出了可应用于这些PID患者的治疗策略， 这些细胞机制通常涉及免疫失调、自身免疫和癌症。
