项目摘要
Discovery of Yellow Fever Virus-Specific Epitopes for Development of an Accurate
Serodiagnostic Assay
Abstract
Antibodies to many pathogenic viruses can be detected in blood, serum and/or saliva. Among these
are many arboviruses, that share endemic regions in the western hemisphere and in other parts of the
world. These include the related flaviviruses yellow fever virus (YFV), dengue virus (DENV), Zika virus
(ZIKV) and West Nile virus (WNV) as well as the alphavirus chikungunya virus (CHIKV). Antibodies to
these viruses are often cross-reactive, making diagnostics for a particular virus challenging. The current
outbreak of yellow fever in Brazil and the high mortality associated with this disease as well as the
recent history of outbreaks in South America and Africa create an urgent need for YFV-specific
serodiagnostics, to aid control of the spread of yellow fever. Moreover, such diagnostics would facilitate
clinical and public health efforts against these and other, related arboviruses. We propose a novel
strategy to develop methods for specific and sensitive detection of antibodies against YFV that do not
cross react with other arboviruses. We will employ an innovative, comprehensive proteomic approach
with a unique serum sample collection that will allow discovery and validation of specific biomarkers
capable of distinguishing YFV from other arboviruses. This will allow us to develop a specific and
sensitive test for YFV infection in Phase II of this project. A practical, sensitive and specific test for YFV
infection is a high priority goal due to the recent outbreak of yellow fever in Brazil, possible future
outbreaks and the likely spread of yellow fever to southern US states bordering the Gulf of Mexico and
Puerto Rico where Aedes spp. mosquitos might rapidly spread the infection.
发现黄热病病毒特异性表位,以开发准确的表位
血清诊断检测
抽象的
许多致病病毒的抗体可以在血液、血清和/或唾液中检测到。 其中
有许多虫媒病毒,它们在西半球和世界其他地区都有流行区域
世界。 这些包括相关的黄病毒、黄热病病毒 (YFV)、登革热病毒 (DENV)、寨卡病毒
(ZIKV)和西尼罗河病毒(WNV)以及甲病毒基孔肯雅病毒(CHIKV)。 抗体
这些病毒通常具有交叉反应性,使得对特定病毒的诊断具有挑战性。 当前的
巴西爆发黄热病以及与这种疾病相关的高死亡率以及
南美洲和非洲近期的疫情爆发迫切需要针对 YFV 的疫苗
血清诊断,以帮助控制黄热病的传播。 此外,此类诊断将有助于
针对这些和其他相关虫媒病毒的临床和公共卫生努力。 我们推荐一本小说
开发针对 YFV 抗体的特异性和灵敏检测方法的策略
与其他虫媒病毒发生交叉反应。 我们将采用创新、全面的蛋白质组学方法
拥有独特的血清样本收集,可以发现和验证特定的生物标志物
能够区分 YFV 和其他虫媒病毒。 这将使我们能够开发一个特定的和
本项目第二阶段对 YFV 感染进行敏感测试。 实用、敏感且具体的 YFV 测试
由于巴西最近爆发了黄热病,感染是一个高度优先的目标,未来可能
黄热病疫情暴发并可能蔓延到美国南部与墨西哥湾接壤的各州和
波多黎各,伊蚊属。 蚊子可能会迅速传播感染。
