Cells of the innate immune system represent the first line of defense against SARS-CoV-2 and play an essential role in activating adaptive immunity, which mediates long-term protection. In addition, the same cells are key drivers of tissue damage by causing the hyperinflammatory state and cytokine storm that makes COVID-19 a deadly disease. Thus, careful dissection of the host-pathogen interaction on a cellular level is essential to understanding SARS-CoV-2 pathogenesis and developing new treatment modalities against COVID-19. In their recent work, Goffinet and colleagues (Kazmierski et al, 2022) investigate the cell-intrinsic responses of human primary peripheral blood mononuclear cells (PBMCs) exposed to SARS coronaviruses.
先天免疫系统的细胞是抵御 SARS-CoV-2 的第一道防线,在激活适应性免疫方面发挥着重要作用,而适应性免疫介导着长期保护。此外,相同的细胞通过引起导致 COVID-19 成为致命疾病的过度炎症状态和细胞因子风暴,成为组织损伤的关键驱动因素。因此,在细胞水平上仔细剖析宿主-病原体的相互作用对于理解 SARS-CoV-2 的发病机制以及开发针对 COVID-19 的新治疗方法至关重要。在他们最近的工作中,Goffinet 和他的同事们(Kazmierski 等人,2022 年)研究了人类原代外周血单核细胞(PBMCs)暴露于 SARS 冠状病毒时的细胞内在反应。
