Abstract

During severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, activated macrophages, dendritic cells (D.C.), neutrophils, and natural killer (N.K.) cells are the first defense against infection. These immune effectors trap and ingest the virus, kill infected epithelial cells, or produce anti-viral cytokines. Evidence suggests that aging, obesity, and mental illness can lead to weakened innate immunity and, thus, are all associated with elevated infection and severe disease progression of coronavirus disease 2019 (COVID-19). Innate immune defense networks play a fundamental role in suppressing viral replication, infection establishment, and viral pathogenesis of SARS-CoV-2 and other respiratory viruses.

先天免疫在严重急性呼吸系统综合征冠状病毒2型感染中的作用
在严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)感染期间,活化的巨噬细胞、树突状细胞(D.C.)、中性粒细胞和自然杀伤细胞(N.K.)是抵御感染的第一道防线。这些免疫效应物捕获并摄入病毒,杀死受感染的上皮细胞,或产生抗病毒细胞因子。有证据表明,衰老、肥胖和精神疾病会导致先天免疫减弱,因此都与2019冠状病毒病(新冠肺炎)的感染和严重疾病进展有关。先天免疫防御网络在抑制严重急性呼吸系统综合征冠状病毒2型和其他呼吸道病毒的病毒复制、感染建立和病毒发病机制方面发挥着重要作用。
