项目摘要

Project Summary/Abstract Monogenic diseases that have a close association with the development of type 1 diabetes have been informative for unraveling critical pathways that keep this disease in check. Examples of success using this approach include the study of AIRE and FOXP3 which have been informative for identifying pathways in the thymus and T regulatory cells that keep type 1 diabetes in check. Here, we will leverage the recent knowledge that gain of function mutations (GOF) in STAT3 are tightly associated with the development of type 1 diabetes by developing a robust animal model of the syndrome. Our specific aims are: Aim 1: Model the effects of STAT3 GOF in a novel mouse model of autoimmune diabetes (NOD.STAT3K392R/+) Aim 2: Identify and characterize key immune cell populations that are defective in the NOD.STAT3K392R/+ model and in patients with similar STAT3 GOF mutations Aim 3: Identify how central tolerance is potentially altered in STAT3 GOF models These studies will be performed in close collaboration with PPG projects 1 (Cooper) and 3 (Marson) and will help improve our understanding of how the immune tolerance is controlled by STAT3 and how alterations in this molecule can provoke type 1 daibetes.

项目摘要/摘要与1型糖尿病的发展有着密切关联的单基因疾病已经阐明该疾病的关键途径的信息。成功的示例方法包括对AIR和FOXP3的研究，这些研究非常有用，可以识别识别途径胸腺和T调节细胞，可控制1型糖尿病。在这里，我们将利用最近的知识 STAT3中功能突变的增益与1型糖尿病的发展密切相关通过开发综合征的强大动物模型。我们的具体目的是： AIM 1：模拟STAT3 GOF在新型自身免疫性糖尿病模型中的影响（nod.stat3k392r/+） AIM 2：确定并表征在点头中有缺陷的关键免疫细胞群体。STAT3K392R/+ 模型和类似STAT3 GOF突变的患者 AIM 3：确定在STAT3 GOF模型中可能改变中央耐受性这些研究将与PPG项目1（Cooper）和3（Marson）密切合作进行，并将有助于提高我们对如何通过STAT3控制免疫耐受性以及如何改变的理解该分子可以引起1型daibetes。
