PROJECT SUMMARY. This is an application for an Urgent Competitive Revision to our Transformative R01 award funded by the NIH INCLUDE Project and NIAID titled ‘Understanding Down Syndrome as an Interferonopathy’. The central hypothesis of the parent award is that hyperactivation of interferon (IFN) signaling causes many of the developmental and clinical hallmarks of DS. In this revision, we will investigate the interplay between IFN hyperactivity, immune dysregulation, COVID19 pathology, and immunity against SARS-CoV-2. We hypothesize that IFN hyperactivity will modify the clinical course of COVID19 in DS, including long term immunological sequalae, while potentially impairing development of cellular and humoral immunity against SARS-CoV-2. Our Specific Aims are: 1. Determine the clinical and immunological characteristics of COVID19 in DS. It is increasingly evident that individuals with DS infected by SARS-CoV-2 are more likely to be hospitalized, develop secondary bacterial infections, and die at younger ages. However, many questions remain unanswered about the clinical course of COVID19 in DS. What are the risk factors for severe COVID19 in DS? Are there treatment modalities that are less or more effective in DS? What are the sequalae of SARS-CoV-2 infection in survivors with DS? Here, we will employ the National COVID Cohort Collaborative (N3C), the DS-Connect® registry, and the Human Trisome Project (HTP) cohort study to generate a definitive assessment of the clinical and immunological characteristics of COVID19 in DS. We will complete parallel analyses of the N3C database and data obtained by the HTP team via electronic health record abstraction and participant surveys to identify differences in early symptoms, immunological parameters, clinical course, risk factors, response to different treatment modalities, and long term sequalae, with emphasis on potential differences by age, sex, race/ethnicity, and geography. 2. Investigate the immune phenotype of a cohort of COVID19 survivors with DS. Our extensive investigation of the immune phenotype of people with DS has revealed strong dysregulation of T and B cell lineages, including changes that could impair the development of cellular and humoral immunity against SARS-CoV-2 and the response to SARS-CoV-2 vaccines. Now, supported by the DS-Connect® registry and the HTP cohort study, we will obtain biospecimens from individuals with DS that survived SARS-CoV-2 infection. We will include these samples in our ongoing pan-omics characterization of IFN hyperactivity and immune dysregulation in DS, while also investigating the development and duration of memory T and B cell responses and production of neutralizing antibodies specific for SARS-CoV-2. Altogether, these synergistic aims, which address multiple aspects of this NOSI, will advance our understanding of the impacts of trisomy 21 and IFN hyperactivity on COVID19 in DS, thus informing the rapid development of customized preventive, diagnostics, and therapeutic strategies for this at-risk population.

项目摘要。 这是对由 NIH 资助的变革性 R01 奖项进行紧急竞争性修订的申请 INCLUDE 项目和 NIAID 的标题为“将唐氏综合症理解为干扰素病”。中央 家长奖的假设是干扰素 (IFN) 信号的过度激活会导致许多 DS 的发育和临床特征。在本次修订中，我们将研究 IFN 之间的相互作用 多动症、免疫失调、COVID19 病理学和针对 SARS-CoV-2 的免疫力。我们假设 IFN 过度活跃将改变 DS 中 COVID19 的临床病程，包括长期免疫学 后遗症，同时可能损害针对 SARS-CoV-2 的细胞和体液免疫的发展。我们的 具体目标是： 1.确定DS中COVID19的临床和免疫学特征。越来越明显 感染 SARS-CoV-2 的 DS 个体更有可能住院并发展继发细菌 感染，并在较年轻时死亡。然而，关于其临床病程的许多问题仍未得到解答。 DS 中的 COVID19。 DS 中出现重症 COVID19 的危险因素有哪些？是否有治疗方法 DS 中更有效还是更有效？ DS 幸存者感染 SARS-CoV-2 后遗症有哪些？在这里，我们 将采用国家新冠肺炎队列协作组织 (N3C)、DS-Connect® 注册中心和人类三体组 项目 (HTP) 队列研究，对临床和免疫学特征进行明确评估 DS 中的 COVID19。我们将完成N3C数据库和HTP团队获得的数据的并行分析 通过电子健康记录提取和参与者调查来识别早期症状的差异， 免疫学参数、临床病程、危险因素、对不同治疗方式的反应以及长期 后遗症，重点是年龄、性别、种族/民族和地理位置的潜在差异。 2. 调查一组患有 DS 的 COVID19 幸存者的免疫表型。我们广泛的调查 DS 患者免疫表型的研究揭示了 T 和 B 细胞谱系的严重失调，包括 可能损害针对 SARS-CoV-2 的细胞和体液免疫发展的变化以及 对 SARS-CoV-2 疫苗的反应。现在，在 DS-Connect® 注册中心和 HTP 队列研究的支持下，我们 将从 SARS-CoV-2 感染后幸存的 DS 个体中获取生物样本。我们将包括这些 我们正在进行的 DS 中 IFN 过度活跃和免疫失调的泛组学表征中的样本，同时 还研究了记忆 T 和 B 细胞反应的发展和持续时间以及中和反应的产生 SARS-CoV-2 特异性抗体。 总而言之，这些协同目标解决了 NOSI 的多个方面，将增进我们的理解 21 三体和 IFN 过度活跃对 DS 中的 COVID19 的影响，从而为快速发展提供信息 为这一高危人群定制预防、诊断和治疗策略。
