 DESCRIPTION (provided by applicant): Autoimmune diseases are chronic debilitating conditions that collectively affect 5 to 8 % of the US population. The high prevalence of autoimmune diseases and the recognition that individuals who develop organ-specific autoimmune conditions have a high likelihood of developing additional autoimmune disorder(s) calls for the development of new technologies that can measure multiple immune reactivities simultaneously in a small sample volume. Detection of these diseases before onset or at early stages can help in making effective treatment decisions. Although multiplexing of up to 13 relevant assays for systemic autoimmune diseases has been achieved, broader panels have not been developed to assess the range of organ-specific autoimmune diseases such as Type 1 Diabetes and Celiac disease. Furthermore, no multiplexed assay panels exist that use a bridging immunoassay format, which provides higher assay specificity as compared to classical serological assay formats. The goal of the proposed program is to develop a novel, highly sensitive, and specific solution-based multiplexed bridging immunoassay panel that can simultaneously detect patient autoantibodies for 25 different autoimmune reactivities relevant to at least 12 major organ-specific autoimmune diseases. The multiplexed autoantibody detection panel will use sensitive Meso Scale Diagnostics, LLC. (MSD) MULTI-ARRAY technology. Our collaborators at the University of Florida, Dr. W.E. Winter and D. Pittmann, will provide their extensive expertise in clinical laboratory assessment of autoimmune diseases related to obesity, diabetes and the metabolic syndrome, and will provide high quality case and control samples for use in panel development, testing, and validation.

 描述（由适用提供）：自身免疫性疾病是长期影响美国人口5至8％的长期衰弱状况。自身免疫性疾病的高患病率以及发展为特定器官特异性自身免疫性疾病的个体具有很有可能发生额外的自身免疫性疾病的可能性很有可能，呼吁开发新技术，这些新技术可以仅在小样本体积中衡量多种免疫反应性。在发病前或早期阶段发现这些疾病可以帮助做出有效的治疗决策。尽管已经实现了多达13种有关系统性自身免疫性疾病的相关测定法，但尚未开发出更广泛的面板来评估器官特异性的自身免疫性疾病（例如1型糖尿病和乳糜泻）。此外，没有使用桥接免疫测定格式的多重测定面板，与经典的血清学测定格式相比，它具有更高的测定特异性。该计划的目标是开发一种新型，高度敏感且基于溶液的多重桥接免疫测定面板，该面板可以轻松检测患者自身抗体的25种不同的自身免疫反应性，至少与至少12种主要的器官特异性自身免疫性疾病有关。多路复用自身抗体检测面板将使用敏感的Meso量表诊断有限责任公司。 （MSD）多阵列技术。我们在佛罗里达大学的合作者W.E.博士Winter和D. Pittmann将在与肥胖，糖尿病和代谢综合征有关的自身免疫性疾病的临床实验室评估方面提供广泛的专业知识，并将提供高质量的病例和控制样本，以用于面板开发，测试和验证。
