研究揭示COVID-19患者I型干扰素活性及炎症反应与疾病程度的关联
法国巴黎大学Benjamin Terrier等研究人员合作揭示COVID-19患者I型干扰素活性及炎症反应与疾病程度的相关性。2020年7月13日,《科学》杂志在线发表了这项成果。
研究人员对50名患有各种疾病严重程度的COVID-19患者进行了综合免疫分析。在重症和重症患者中研究人员观察到独特的表型,包括高度受损的I型干扰素(IFN)反应(以无IFN-β和低的IFN-α产生和活性为特征),伴有持续的病毒载量以及加重疾病恶化的炎症反应。炎症部分由转录因子NF-κB驱动,其特征是肿瘤坏死因子(TNF)-α和白介素(IL)-6的产生和信号增加。
这些数据表明血液中的I型IFN缺乏可能是严重COVID-19的标志,并为联合治疗方法提供了依据。
据介绍,2019冠状病毒疾病(COVID-19)的特征在于疾病进展的不同模式,从而表明这其中存在多种宿主免疫反应。

Abstract: Abstract Coronavirus disease 2019 (COVID-19) is characterized
by distinct patterns of disease progression suggesting diverse host
immune responses. We performed an integrated immune analysis on a
cohort of 50 COVID-19 patients with various disease severity. A unique
phenotype was observed in severe and critical patients, consisting of a
highly impaired interferon (IFN) type I response (characterized by no IFN-
β and low IFN-α production and activity), associated with a persistent
blood viral load and an exacerbated inflammatory response.
Inflammation was partially driven by the transcriptional factor NF-κB and
characterized by increased tumor necrosis factor (TNF)-α and interleukin
(IL)-6 production and signaling. These data suggest that type-I IFN
deficiency in the blood could be a hallmark of severe COVID-19 and
provide a rationale for combined therapeutic approaches.
