Science:新冠肺炎(COVID-19)时,用干扰素IFN-λ治疗有益还是有害?

免疫系统产生的干扰素和其他细胞因子是抵御病毒感染的重要防御手段,但正如我们在COVID-19中看到的那样,它们也会导致破坏性的、可能危及生命的肺部炎症。最近的证据提示着一种称为III型干扰素或干扰素λ(IFN-λ)的干扰素可以对抗病毒感染,同时限制这种炎症损伤。这导致人们开展临床试验来测试III型干扰素是否可用来治疗COVID-19。

不过,在一项新的研究中,来自意大利和美国的研究人员提供证据表明III型干扰素可以增加肺部出现危及生命的细菌“超级感染”风险。在流感和COVID-19中均可发生超级感染。这些研究人员提醒道,在COVID-19病程后期给予III型干扰素可能弊大于利。相关研究结果于2020年6月11日在线发表在Science期刊上,论文标题为“Type III interferons disrupt the lung epithelial barrier upon viral recognition”。

论文通讯作者、美国波士顿儿童医院免疫学家Ivan Zanoni博士说,“我们的数据表明,SARS-CoV-2抑制了上呼吸道中干扰素的产生,削弱了免疫反应,帮助这种冠状病毒存活。但是,当这种冠状病毒到达下呼吸道时,会出现旺盛的免疫反应,包括Ⅲ型干扰素上调,我们认为这是有害的。”

Zanoni及其研究团队首先测试了来自重症COVID-19患者和健康对照者的样本。III型干扰素在这些患者的鼻咽拭子样本中增加不多,但在他们的肺液中明显升高。

这些研究人员随后将小鼠暴露在合成的病毒RNA中,以模拟下呼吸道中SARS-CoV-2感染的影响。他们发现,与对照小鼠相比,这些受试小鼠肺部的III型干扰素水平明显上升,III型干扰素的持续产生使得肺部无法维持其保护性表面屏障。这接着使得这些小鼠更容易受到金黄色葡萄球菌的致命性细菌感染:实验显示,与对照组小鼠相比,这些受试小鼠具有增加的细菌数量和更高的死亡率。

Zanoni说,“还有很多东西需要了解,但是看起来干扰素产生的位置和时间是关键。在SARS-CoV-2感染的早期,当这种病毒进入上呼吸道时,用重组干扰素和其他抗病毒药物进行干预可能很重要。但是,在过些时候,当下呼吸道中的炎症高度加重时,阻断由干扰素和其他炎症性细胞因子启动的信号级联反应可能较为重要,这种阻断可能是用抗炎药物实现的。”
