INTRACELLULAR LOCALIZATION OF RNA VIRUS COMPLEXES

我们感兴趣的是细胞对病毒感染的反应， 与宿主发病机制的关系 作为我们的模特， 小鼠巨噬细胞的孟戈病毒感染。 门戈病毒感染是 对研究门戈病毒感染的发病机制有一定的意义。 小鼠被很好地表征。 在孟戈病毒感染期间， 哨兵蛋白，蛋白激酶R（PKR），是从一个蛋白质的位置重新定位。 均匀的胞质分布到核周区域。 PKR拥有 被认为是重要的细胞反应， 其他病毒感染，包括FHV- 1、腺病毒和牛痘 病毒 因此，PKR可能在细胞反应中具有普遍作用， 病毒感染 了解门戈病毒如何感染埃博拉病毒 PKR在感染细胞和h6 w中的重新定位， 细胞对病毒感染的反应，我们已经创建了一个小组， 减毒门戈病毒。 我们希望用间接免疫荧光法 和共聚焦显微镜，以确定这些病毒是否受损， 诱导PKR在感染细胞中重新定位的能力。

We are interested in the cellular response to viral infection and how that correlates to host pathogenesis. As our model, we study mengo virus infection of murine macrophages. Mengo virus infection is useful to study in that the pathogenesis of mengo virus infection in mice is well characterized. During mengo virus infection, a cellular sentinel protein, protein kinase R (PKR), is relocalized from a uniform cytoplasmic distribution to a perinuclear locale. PKR has been implicated as being important in the cellular response to many other virus infections including, FHV- 1, adenovirus, and vaccinia virus. So, PKR may have a universal role in the cellular response to viral infections. To understand how mengo virus infection elicits a relocalization of PKR in infected cells and h6w this is important in the cellular response to viral infection, we have created a panel of attenuated mengo viruses. We wish to use indirect immunofluorescence and confocal microscopy to determine if these viruses are impaired in the ability to elicit a relocalization of PKR in infected cells.
