甲型流感病毒(iav)是常见的呼吸道病毒。小鼠感染禽流感病毒模型对研究禽流感病毒感染的机制和病理有重要意义。在这里,我们提出了一种通过鼻内给药治疗小鼠IAV感染的详细方案。我们详细介绍了小鼠肺组织的处理过程,然后描述了几种方法的病毒载量测定,包括RNA、蛋白质或斑块形成单位测定。本方案可适用于其他流感毒株或呼吸道病毒。有关使用和执行本协议的完整详情,请参阅。用RNA、蛋白质或斑块形成单位测定病毒载量通过FACS分析和组织学分析病毒定位甲型流感病毒(IAV)是常见的呼吸道病毒。小鼠感染禽流感病毒模型对研究禽流感病毒感染的机制和病理有重要意义。在这里,我们提出了一种通过鼻内给药治疗小鼠IAV感染的详细方案。我们详细介绍了小鼠肺组织的处理过程,然后描述了几种方法的病毒载量测定,包括RNA、蛋白质或斑块形成单位测定。本方案可适用于其他流感毒株或呼吸道病毒。
Influenza A viruses (IAVs) are common respiratory viruses. Mouse models of IAV infection are valuable to study the mechanisms of IAV infection and pathology. Here, we present a detailed protocol for IAV infection of mice via intranasal administration. We detail the processing of mouse lung tissue and then describe the determination of viral load by several approaches including RNA, protein, or plaque-forming unit assays. This protocol may be adapted to other influenza strains or respiratory viruses. For complete details on the use and execution of this protocol, please refer to.
