Abstract This proposal seeks to test two hypotheses regarding the Multisystem Inflammatory Syndrome (MIS-C) recently identified in children and young adults infected with SARS-CoV-2. We hypothesize that there is a spectrum of disease from severe acute disease to MIS-C. Severe Cov acute disease is associated with low interferon production, poor control of virus and a germinal center derived antibody response to the virus leading to long term immunity while MIS- C is associated with high interferon, efficient control of virus, but an extrafollicular derived antibody response with poor long term immunity. We will test this hypothesis through a genetic analysis, analysis of serum cytokines and analysis of anti-viral antibodies. We also hypothesize that plasma metabolic profile of subjects with MIS-C will predict short term cardiac dysfunction and long term cardiac damage.

抽象的 该提案旨在检验有关多系统炎症综合征的两个假设 （MIS-C）最近在感染SARS-COV-2的儿童和年轻人中发现了。我们 假设从严重的急性疾病到MIS-C有很多疾病。严重 COV急性疾病与干扰素的产生低，对病毒的控制不良和A 生发中心衍生出对病毒的抗体反应，导致长期免疫力，而错误 C与高干扰素，有效控制病毒有关，但是衍生出毛囊 长期免疫力较差的抗体反应。我们将通过遗传来检验该假设 分析，血清细胞因子分析和抗病毒抗体的分析。我们也假设 MIS-C受试者的血浆代谢概况可以预测短期心脏功能障碍 和长期心脏损伤。
