PROJECT SUMMARY/ABSTRACT A growing body of evidence suggests that COVID-19 emulates many aspects of inflammatory and autoimmune diseases. Circulating autoantibodies have been detected in serum of COVID-19 patients where they have an antigen profile reminiscent of the lupus-associated thrombophilia known as antiphospholipid syndrome. While the association between infection, critical illness, and the induction of autoantibodies has long been recognized, pathogenesis and persistence of these antibodies—and most importantly the extent to which they may be therapeutic targets—have not been well defined. This award will play a critical role in helping me achieve my long-term career goals, which include: (1) Establishing a unique niche in the area of infection- associated autoimmunity; (2) Becoming an independent investigator at a leading medical research institution; and (3) Mentoring and fostering the development of trainees. These objectives will be reached by incorporating both a strong mentorship environment and a formal instructional plan. Mentorship Environment: I am currently an Assistant Professor in the Division of Rheumatology at the University of Michigan with 75% of my effort protected for research. Over the past two years, I have received strong training from Dr. Jason Knight in antiphospholipid syndrome pathogenesis. With this proposal, I am seeking support for a new research endeavor, as I turn my attention to the thromboinflammatory consequences of infection-associated autoimmunity. I have assembled a strong team of advisors, all experts in their respective fields and carefully selected to compliment the proposed project and career development. Formal Instruction: My scientific goals for this proposal include: (1) To expertly assess relevant measures of thromboinflammation; (2) To effectively manipulate and characterize mouse models; and (3) To develop laboratory skills in support of the study of autoantibodies and NETs in sepsis. Equally important are my career development goals, which include: (1) To learn to write innovative proposals in support of ethically-conducted research in humans and animals; (2) To enhance leadership, mentoring, and team-building skills; and (3) To continue to improve my written and oral communication. These goals will be achieved through a combination of mentorship, formal didactic instruction, and experimentation. Research: I plan to use COVID-19 and other severe infections as a window into the origins of autoimmunity and—in doing so—determine thromboinflammatory mechanisms of infection-associated autoantibodies. Aim 1 will elucidate the durability and clinical interactions of antiphospholipid antibodies and anti-NET antibodies in patients hospitalized with either COVID-19 or non-COVID sepsis. Aim 2 will characterize pathogenic and protective functions of infection-associated autoantibodies.

项目摘要/摘要 越来越多的证据表明，COVID-19模仿炎症和自身免疫的许多方面 疾病。在199例患者的血清中检测到循环自身抗体 抗原剖面提醒与狼疮相关的血栓形成症，称为抗磷脂综合征。尽管 长期以 公认的，这些抗体的发病机理和持久性，最重要的是它们的程度 可能是热目标 - 未定义。该奖项将在帮助我方面发挥关键作用 实现我的长期职业目标，其中包括：（1）在感染领域建立独特的利基市场 - 相关的自身免疫性； （2）成为领先的医学研究机构的独立研究人员； （3）指导和促进学员的发展。这些目标将通过合并 既有强大的心态环境和正式的教学计划。 指导环境：我目前是风湿病学系的助理教授 密歇根大学有75％的努力进行研究。在过去的两年中，我收到了 杰森·奈特（Jason Knight）博士在抗磷脂综合征发病机理中进行了强有力的训练。有了这个建议，我是 寻求支持新的研究努力，因为我将注意力转向血栓炎性 与感染相关的自身免疫的后果。我组建了一个强大的顾问团队，所有专家 他们各自的领域并精心选择以补充拟议的项目和职业发展。 正式教学：我针对该提案的科学目标包括：（1）专业评估相关措施 血栓炎； （2）有效操纵和表征小鼠模型； （3）发展 实验室技能支持败血症中自身抗体和网的研究。同样重要的是我的职业 发展目标包括：（1）学会编写创新的建议以支持道德规范 人类和动物的研究； （2）提高领导力，心理和团队建设技能； （3）到 继续改善我的书面和口头交流。这些目标将通过结合 识别，正式的教学教学和实验。 研究：我计划使用Covid-19和其他严重感染作为自身免疫起源的窗口 在这样做的过程中，确定性的血栓促性自身抗体机制。目标1 将阐明抗磷脂抗体和抗NET抗体的耐用性和临床相互作用 患有COVID-19或非卵巢败血症的患者。 AIM 2将表征致病性和 感染相关自身抗体的保护功能。
