项目摘要

ABSTRACT Flaviviruses are important human pathogens including viruses such as West Nile, dengue, and Zika. No specific treatments or vaccines are available against these infections, and no biomarkers exist that allow predicting their outcome, characterized by important clinical variability. Understanding innate antiviral immune responses against flaviviruses, could lead to the identification of disease susceptibility biomarkers and therapeutic targets. We recently demonstrated that the type I interferon-stimulated protein Schlafen 11 (SLFN11) is a novel and potent flavivirus restriction factor. In this application we aim to define, at the molecular level, several aspects of the mechanism of action of SLFN11 and determine the anti-flavivirus activity of other members of the SLFN family, as well as the in vivo relevance of this defense system. Therefore, this investigation is highly relevant and will significantly advance our understanding of the antiviral mechanism of action of SLFN proteins, which is currently unknown.

抽象的黄病毒是重要的人类病原体，包括西尼罗河病毒、登革热病毒和寨卡病毒等病毒。不针对这些感染有特定的治疗方法或疫苗，并且不存在允许的生物标志物预测其结果，其特征是重要的临床变异性。了解先天抗病毒免疫针对黄病毒的反应，可能导致疾病易感性生物标志物的鉴定，治疗目标。我们最近证明 I 型干扰素刺激蛋白 Schlafen 11 (SLFN11) 是一种新型、有效的黄病毒限制因子。在此应用中，我们的目标是在分子水平上定义水平，SLFN11作用机制的几个方面并确定其他药物的抗黄病毒活性 SLFN 家族的成员，以及该防御系统的体内相关性。因此，这研究具有高度相关性，将显着增进我们对抗病毒机制的理解 SLFN 蛋白的作用，目前尚不清楚。
