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?

项目概要功能丧失突变和先天抗病毒蛋白（例如 OAS2 和 OASL）的抑制与高由于干扰素的诱导，这些抗病毒蛋白通常会降低小鼠和人类的病毒感染率。被称为干扰素刺激基因（ISG），而重组干扰素会刺激这些抗病毒药物的产生。 I 型干扰素的严重毒性是其治疗用途的主要限制。阿昔洛韦等抗病毒药物极有可能引发弱势患者中性粒细胞减少症和肾毒性因此，对新的抗病毒疗法的临床需求尚未得到满足。通过全面了解内源性抗病毒蛋白的干扰素非依赖性调节来解决这一问题通过识别这种极其有效的天然抗病毒途径的激活来确定治疗和预防的目标。拟议的工作将回答重要问题：1）哪些独立于干扰素的信号和途径可以诱导 2) 上皮抗病毒先天免疫在单细胞水平上是否存在差异？ 3) 哪些因素影响？合作诱导先天抗病毒免疫？
