项目摘要

Project Summary Recent genetic studies have identified numerous genetic variations that are associated with higher risk of autoimmune diseases. For example, several genetic variations at the SIRPG gene are associated with higher risk of type 1 diabetes. SIRPG is expressed almost exclusively in T lymphocytes. However, its physiological function is still unknown due to the lack of a mouse homologue. Nor do we understand how its genetic variations contribute to the pathogenesis of type 1 diabetes. These important questions will be addressed in this project with cutting edge genetic engineering technology to ablate SIRPG or reproduce its genetic variations in human T cells. Data generated from this project will advance our understanding of not only the function of SIRPG but also the pathogenesis of type 1 diabetes, and eventually lead to novel therapeutic approaches of autoimmune diseases.

项目摘要最近的遗传研究已经确定了许多与较高风险有关的遗传变异自身免疫性疾病。例如，SIRPG基因的几种遗传变异与较高 1型糖尿病的风险。 SIRPG几乎完全在T淋巴细胞中表达。但是，它的生理由于缺乏小鼠同源物，功能仍然未知。我们也不了解其遗传变异有助于1型糖尿病的发病机理。这些重要问题将在该项目采用尖端的基因工程技术来消灭SIRPG或重现其遗传人T细胞的变化。该项目产生的数据不仅会提高我们对 SIRPG的功能以及1型糖尿病的发病机理，并最终导致新型治疗自身免疫性疾病的方法。
