项目摘要

Project Summary Loss-of-function mutations and suppression of innate antiviral proteins, such as OAS2 and OASL are associated with high viral infection rates in mice and humans. Because of their induction by interferons, these antiviral proteins are often referred to as interferon-stimulated genes (ISG). While recombinant interferon stimulates production of these antiviral proteins, type I interferon’s severe toxicity is the major limitation in its therapeutic utility. Additionally, pharmacological antivirals, such as acyclovir, have a high risk for triggering neutropenia and nephrotoxicity in vulnerable patient populations. Therefore, there is a significant unmet clinical need for new antiviral therapeutics. This need can be addressed by developing a full understanding of interferon-independent regulation of endogenous antiviral proteins and identifying targets for therapy and prevention by activation of this incredibly potent natural antiviral pathway. Our proposed work will answer important question: 1) Which interferon-independent signals and pathways can induce antiviral competence? 2) Does epithelial antiviral innate immunity differ on a single cell level? 3) What factors collaborate in the induction of innate antiviral immunity?

项目摘要功能丧失的突变和抑制先天抗病毒蛋白（例如OAS2和OASL）与高有关小鼠和人类的病毒感染率。由于它们被干扰素诱导，这些抗病毒蛋白通常是称为干扰素刺激的基因（ISG）。重组干扰素刺激这些抗病毒的产生蛋白质，I型干扰素的严重毒性是其治疗效用的主要局限性。另外，药物抗病毒药，例如阿昔洛韦，在脆弱患者中触发中性粒细胞减少和肾毒性的风险很高人群。因此，对新的抗病毒疗法的临床需求很大。这可能是通过对内源性抗病毒蛋白的干扰素调节和通过激活这种难以置信的天然抗病毒途径来识别治疗和预防靶标。我们的拟议的工作将回答重要问题：1）哪些与干扰素无关的信号和途径可以诱导抗病毒能力？ 2）单个细胞水平上的上皮抗病毒先天免疫差异吗？ 3）什么因素合作诱导先天抗病毒免疫？
