In the past two decades, two beta-coronaviruses, severe acute respiratory syndrome-related coronavirus (SARS-CoV-1) and the Middle East respiratory syndrome-related coronavirus (MERS-CoV), have infected approximately 8000 and 2500 across the globe, respectively (de Wit et al. 2016; Amanat and Krammer 2020). The current viral pandemic, caused by SARS-CoV-2, has already affected 4.23 M in less than a year. Of greater concern, the disease caused by SARS-CoV-2, COVID-19, still has a rapidly increasing global burden (Wu et al. 2020; Zhu et al. 2020). To better understand the biology of COVID-19, an initial barrage of studies compared SARS-CoV-2 to other respiratory viruses: MERS-CoV, SARS-CoV-1, human parainfluenza virus 3 (HPIV3), respiratory syncytial virus (RSV), and Influenza A Virus (IAV). These studies indicate that SARS-CoV-2 infected individuals have a consistent chemokine signature comprising cytokines and monocyte-associated chemokines (CCL2 and CCL8). Therefore, it appears that monocyte cytokine production, particularly in those with a diminished innate immunity, is a driving feature of COVID-19 infection.

冠状病毒:焦点从干扰素反应转向其他炎症靶点。



在过去的二十年中,两种β冠状病毒,即严重急性呼吸综合征相关冠状病毒(SARS-CoV-1)和中东呼吸综合征相关冠状病毒(MERS-CoV),已感染全球约8000人和2500人,分别(de Wit 等人,2016 年;Amanat 和 Krammer,2020 年)。当前由 SARS-CoV-2 引起的病毒大流行在不到一年的时间里已经影响了 423 万人。更令人担忧的是,由 SARS-CoV-2(即 COVID-19)引起的疾病的全球负担仍在迅速增加(Wu 等人,2020 年;Zhu 等人,2020 年)。为了更好地了解 COVID-19 的生物学特性,一系列初步研究将 SARS-CoV-2 与其他呼吸道病毒进行了比较:MERS-CoV、SARS-CoV-1、人类副流感病毒 3 (HPIV3)、呼吸道合胞病毒 (RSV)和甲型流感病毒 (IAV)。这些研究表明,SARS-CoV-2 感染者具有一致的趋化因子特征,包括细胞因子和单核细胞相关趋化因子(CCL2 和 CCL8)。因此,单核细胞细胞因子的产生,尤其是先天免疫力下降的单核细胞细胞因子的产生,似乎是 COVID-19 感染的一个驱动特征。
