The proposed Denver Autoimmunity Center of Excellence combines the efforts of investigators with faculty appointments at the University of Colorado Health Sciences Center. Affiliated institutions include the Barbara Davis Center for Childhood Diabetes, the National Jewish Medical and Research Center, the Children's Hospital of Denver, the University Hospital of Denver, the Rocky Mountain Multiple Sclerosis Center, as well as the Denver Arthritis Clinic. Faculty have been recruited from the Departments of Immunology, Pediatrics, Medicine, Neurology, Dermatology, Pathology, and Preventative Medicine/Epidemiology, and the Human Medical Genetics Program. Within the Departments of Pediatrics and Medicine, subspecialties include endocrinology, rheumatology, clinical immunology, nephrology, pulmonary and gastroenterology. There are unique resources for clinical investigation and strong basic faculty, and in many instances a track record for combining basic and clinical investigation. The proposed Autoimmunity Center includes a strong research and clinical base in type 1 diabetes, celiac disease, systemic lupus, rheumatoid arthritis, multiple sclerosis, autoimmune skin disease, autoimmune pulmonary diseases as well as other autoimmune disorders. One unique clinical resource involves ongoing studies of newborns from both the general population and relatives of patients with type 1 diabetes who are HLA typed using cord blood and then evaluated prospectively for the development of autoantibodies associated with type 1A diabetes and disease A major strength of the current proposal we believe sit he breadth of work in Denver studying T cell recognition and biology, genetics, and the biology of inflammatory and cytokine mediators. In the current proposal, two clinical trials are proposed. Clinical Project 1 will evaluate subcutaneous insulin vaccination to prevent the appearance of anti-islet autoantibodies in infants at high risk for the development of autoantibodies and disease. Clinical Project 2 will test humanized anti-C5 mAbs in patients with active lupus nephritis. The three proposed basic components are: 1) to define the T cell specificities and distribution of insulin- and islet antigen- reactive T cells in murine models and patients with type 1; diabetes; 2) to determine the effects of inhibition of IL-18 and complement on cytokine patients with type1 diabetes; 2) to determine the effects of inhibition of IL-18 and complement on cytokine production and disease in collagen- induced arthritis and rheumatoid synovium; and 3) to define the non- MHC genetic contributions to different clinical subtypes of autoimmune polyendocrine syndrome II. The three basic projects will provide important information to design future clinical trials , to monitor the effectiveness of immunologic therapies, and/or provide surrogate markers to correlate with immunologic therapies in autoimmune diseases.

拟议中的丹佛自身免疫卓越中心将研究人员的努力与科罗拉多大学健康科学中心的教师任命相结合。附属机构包括芭芭拉·戴维斯儿童糖尿病中心、国家犹太医学和研究中心、丹佛儿童医院、丹佛大学医院、落基山多发性硬化症中心以及丹佛关节炎诊所。教师已从免疫学，儿科学，医学，神经病学，皮肤病学，病理学，预防医学/流行病学和人类医学遗传学计划的部门招募。在儿科和内科，亚专业包括内分泌学，风湿病学，临床免疫学，肾脏病学，肺病和胃肠病学。有独特的资源，临床研究和强大的基础教师，并在许多情况下，结合基础和临床研究的跟踪记录。拟议的自身免疫中心包括1型糖尿病，乳糜泻，系统性狼疮，类风湿性关节炎，多发性硬化症，自身免疫性皮肤病，自身免疫性肺病以及其他自身免疫性疾病的强大研究和临床基础。一个独特的临床资源涉及正在进行的研究新生儿从一般人群和亲属的1型糖尿病患者谁是HLA分型使用脐带血，然后评估前瞻性的发展自身抗体与1A型糖尿病和疾病的一个主要优势，我们相信坐在他的工作广度在丹佛研究T细胞识别和生物学，遗传学，以及炎症和细胞因子介质的生物学。在目前的提案中，提出了两项临床试验。临床项目1将评估皮下胰岛素接种，以预防自身抗体和疾病发生风险高的婴儿出现抗胰岛自身抗体。临床项目2将在活动性狼疮肾炎患者中测试人源化抗C5 mAb。提出的三个基本组成部分是：1）确定小鼠模型和1型糖尿病患者中的T细胞特异性和胰岛素和胰岛抗原反应性T细胞的分布; 2）确定IL-18和补体抑制对1型糖尿病患者细胞因子的影响; 2）确定抑制IL-18和补体对胶原诱导的关节炎和类风湿性滑膜中细胞因子产生和疾病的影响;明确非MHC基因对自身免疫性多内分泌综合征II型不同临床亚型的影响。这三个基本项目将为设计未来的临床试验提供重要信息，以监测免疫疗法的有效性，和/或提供与自身免疫性疾病的免疫疗法相关的替代标志物。
