Finding an effective therapy against diseases caused by flaviviruses remains a challenge. Here, we present a protocol to test Food and Drug Administration-approved drugs that inhibit host nuclear protein import, promoting a reduction of dengue infection. We describe steps for analyzing the drug effect on nuclear import inhibition of cellular and viral proteins by confocal microscopy or western blotting. We then describe procedures for measuring the antiviral drug effects on virus-infected cells by flow cytometry and testing drug efficacy in dengue-infected AG129 mice by survival assays. For complete details on the use and execution of this protocol, please refer to Palacios-Rápalo et al..
寻找针对黄病毒引起的疾病的有效疗法仍然是一个挑战。在这里,我们提出了一个测试食品和药物管理局批准的抑制宿主核蛋白输入的药物的方案,以促进登革热感染的减少。我们描述了通过共聚焦显微镜或蛋白质印迹分析药物对细胞和病毒蛋白核输入抑制作用的步骤。然后,我们描述了通过流式细胞术测量抗病毒药物对感染病毒的细胞的作用以及通过生存分析测试登革热感染的 AG129 小鼠中的药物功效的程序。有关此方案的使用和执行的完整详细信息,请参阅 Palacios-Rápalo 等人的研究。
