PROJECT SUMMARY Type 1 Diabetes (T1D) is an autoimmune disease affecting over 1.6 million people in the United States, and more than 5 million Americans are expected to be diagnosed with T1D by 2050. Clinical T1D is preceded by an occult period of autoimmune beta cell loss and dysfunction. Disease prediction can be performed for clinical trial purposes, with a combination of islet autoantibodies, genetic markers, and metabolic markers. However, the predictive ability in the short term, particularly early in the disease or as an early marker of response to therapy, is often inadequate. This results in needing longer and more extensive clinical trials for T1D interventions. Islet- derived exosomes (or small extracellular vesicles produced by pancreatic beta cells or nearby cells within the peri-islet environment) may reveal beta cell dysfunction and islet inflammation and are believed as promising biomarkers for early detection and monitoring of T1D, but little has been explored yet. Thus, there is an urgent and unmet need to identify and characterize islet-derived exosomes for the early detection of T1D, particularly during the asymptomatic phase. Our overall objective is to create an integrated exosome isolation and analysis system for the high throughput screening and identification of islet-derived exosomal markers with the rapid purification and specific detection of islet-derived exosomes in T1D. The rationale for the proposed work is to screen for pancreatic islet-specific exosomal markers and further develop an Exosome Technology with Optoelectronics Lab-on-chip (EXTOL) system for rapid and specific capturing and analyzing islet-derived exosomes in T1D. Then, we will validate the EXTOL system and screened exosomal markers using clinical samples from T1D patients and appropriate controls. The ultimate product of this study is to provide a new platform to screen, identify, and analyze exosomal markers for rapid and specific detection of asymptomatic T1D.

项目概要 1 型糖尿病 (T1D) 是一种自身免疫性疾病，影响着美国超过 160 万人，并且 到 2050 年，预计将有超过 500 万美国人被诊断出患有 T1D。临床 T1D 之前会出现 自身免疫β细胞丢失和功能障碍的隐匿期。可进行疾病预测以进行临床试验 目的，结合胰岛自身抗体、遗传标记和代谢标记。然而， 短期预测能力，特别是在疾病早期或作为治疗反应的早期标志， 往往是不够的。这导致 T1D 干预措施需要更长、更广泛的临床试验。胰岛- 衍生的外泌体（或由胰腺β细胞或附近细胞产生的小细胞外囊泡） 胰岛周围环境）可能揭示β细胞功能障碍和胰岛炎症，并被认为是有希望的 早期检测和监测 T1D 的生物标志物，但目前尚未进行探索。因此，有一个紧急的 识别和表征胰岛来源的外泌体以早期检测 T1D 的需求尚未得到满足，特别是 在无症状阶段。我们的总体目标是创建集成的外泌体分离和分析 用于高通量筛选和鉴定胰岛来源的外泌体标记物的系统 T1D 中胰岛来源的外泌体的纯化和特异性检测。拟议工作的理由是 筛选胰岛特异性外泌体标记物并进一步开发外泌体技术 用于快速、特异性捕获和分析胰岛来源的光电子芯片实验室 ​​(EXTOL) 系统 T1D 中的外泌体。然后，我们将验证 EXTOL 系统并利用临床筛选外泌体标志物 来自 T1D 患者和适当对照的样本。这项研究的最终成果是提供一种新的 筛选、识别和分析外泌体标记物的平台，用于快速、特异性地检测无症状患者 T1D。
