由于对宿主-病原体相互作用的不完全理解、有限的治疗方法和缺乏通用疫苗,预防和治疗流感病毒感染仍然是一个挑战。到目前为止,还缺乏在活体动物中真实的实时监测流感病毒感染过程的方法。在这里,我们报告可视化流感病毒感染活小鼠使用工程复制能力携带荧光素酶报告基因的甲型流感病毒。鼻内接种后,在活体小鼠的胸部和鼻咽部传代中可检测到生物发光。胸部生物发光的强度与肺部感染的剂量和病毒载量相关。抗病毒治疗后,感染小鼠胸部的生物发光会减弱。这项工作提供了一种新的方法,使实时研究流感病毒感染和抗病毒治疗在活体动物中的作用。 能够监测活体动物感染的流感病毒感染小鼠模型很少。在此,Pan等人描述了一种表达荧光素酶的工程化流感病毒,其能够实现病毒感染的实时体内可视化和抗病毒药物的评估。
Preventing and treating influenza virus infection remain a challenge because of incomplete understanding of the host–pathogen interactions, limited therapeutics and lack of a universal vaccine. So far, methods for monitoring the course of infection with influenza virus in real time in living animals are lacking. Here we report the visualization of influenza viral infection in living mice using an engineered replication-competent influenza A virus carrying luciferase reporter gene. After intranasal inoculation, bioluminescence can be detected in the chest and nasopharyngeal passage of living mice. The intensity of bioluminescence in the chest correlates with the dosage of infection and the viral load in the lung. Bioluminescence in the chest of infected mice diminishes on antiviral treatment. This work provides a novel approach that enables real-time study of influenza virus infection and effects of antiviral therapeutics in living animals. Mouse models of influenza infection that permit monitoring of infection in living animals are scarce. Here Pan et al. describe an engineered influenza virus expressing luciferase, which enables real-time in vivo visualization of viral infection and assessment of antiviral drugs.
