The COVID-19 clinical syndrome caused by the SARS-CoV-2 virus has the potential to cause significant morbidity and mortality in previously healthy patients. A significant observation is that although this infection may result in a self-limiting upper respiratory infection or mild pneumonia in some patients, other patients experience progression of respiratory symptoms to requirement of intubation for mechanical respiratory support and death due to severe respiratory failure. This clinical observation strongly suggests that differences in host immunologic response are the determinative factor in clinical outcome. We hypothesize that the proposed systems immunology, biostatistical and computational modeling approaches, coupled with detailed clinical phenotype of hospitalized COVID-19 patients will provide a new framework to interpret the interplay between SARS-CoV-2 virus and the host, and the relationship with clinical outcome. Project 1 will assess the frequency and function of SARS-CoV-2 virus antigen specific T cells and evaluate their breadth and clonality of their TCR repertoire with clinical outcome. Project 2 will determine epigenetic signatures of the immune response to the SARS-CoV-2 virus across short, middle and long-term times and identify DNA methylation- based markers of anti-viral immunity and clinical outcome. With this approach, we will create a unique resource of highly annotated longitudinal data on SARS-CoV-2 virus infection, which will enable the development of novel diagnostic strategies and therapeutics to treat or prevent SARS-CoV-2 virus infection.

由SARS-COV-2病毒引起的Covid-19-19临床综合征具有引起重要的 以前健康患者的发病率和死亡率。一个重要的观察结果是，尽管这种感染 可能导致一些患者的自限制上呼吸道感染或轻度肺炎 呼吸症状的经验发展到需要插管机械呼吸道的需求 由于严重的呼吸衰竭而导致的支持和死亡。该临床观察强烈表明差异 在宿主免疫反应中，是临床结果的决定性因素。我们假设 提议的系统免疫学，生物统计和计算建模方法，再加上详细的 住院Covid-19患者的临床表型将提供一个新框架来解释相互作用 在SARS-COV-2病毒和宿主之间，以及与临床结果的关系。项目1将评估 SARS-COV-2病毒抗原特异性T细胞的频率和功能，并评估其广度和克隆性 他们的TCR曲目具有临床结果。项目2将确定免疫的表观遗传特征 在短期，中和长期内对SARS-COV-2病毒的反应，并鉴定DNA甲基化 - 基于抗病毒免疫和临床结果的标志物。通过这种方法，我们将创建一个独特的资源 关于SARS-COV-2病毒感染的高度注释的纵向数据，这将使能够发展 新的诊断策略和治疗或预防SARS-COV-2病毒感染的治疗疗法。
