项目摘要
Project Summary / Abstract
The Eastern Province of Sierra Leone has the world’s highest incidence of Lassa fever. Members of this
research team have been working on Lassa fever at the Kenema Government Hospital (KGH) for over twelve
years. The 2013-16 West African Ebola epidemic began less than a four-hour drive from KGH and was the
first Ebola outbreak to occur in an area close to an existing facility for viral hemorrhagic fever basic and
clinical research. KGH manages up to 600 suspected Lassa fever patients per year, and Kenema and
surrounding districts experienced a large number of Ebola case. We will leverage existing samples from these
established cohorts of humans infected with Lassa fever or Ebola. While it is well established that
asymptomatic or mildly symptomatic infections occur in both Lassa fever and Ebola, it is unknown which host
factors determine the progression to fulminant hemorrhagic fever. Likewise, a substantial portion of Lassa
fever and Ebola survivors develop a plethora of serious sequelae, but factors that predicate these
complications remain elusive. Our research program supports both Lassa fever and Ebola survivor groups.
We propose to integrate experimental approaches and computational modeling to test and validate
hypotheses of significance to Lassa fever and Ebola. Our assembled team has a track record of collaboration,
unique expertise with both Lassa virus and Ebola virus and the appropriate multidisciplinary representation in
systems and computational biology, virology, immunology, genomics, proteomics, machine learning,
statistical methods and modeling required to execute the proposed program. Our overall goal in Project 1 is to
generate an integrated dataset that can be used to build predictive models of patient outcomes in Lassa fever
and Ebola. Studies proposed under Specific Aim 1 will define physiological attributes that distinguish Lassa
fever and Ebola survivors and non-survivors, and individuals that develop serious sequelae. Specific Aim 2
will elucidate the evolution and function of successful antibody networks in Ebola and Lassa fever survivors. T
cell dynamics and the role human leukocyte antigens leading to successful clearance of Ebola virus and
Lassa virus will be defined in studies described in Specific Aim 3. In Specific Aim 4 we will develop and test
predictive models for the role of host factors in Lassa fever and Ebola outcome. Project 1 on host factors
complements the studies described in Project 2 on viral factors and integrates with and utilizes each of the
Cores.
项目概要/摘要
塞拉利昂东部省是世界上拉沙热发病率最高的地区。 该成员
研究小组在凯内马政府医院 (KGH) 从事拉沙热研究已有超过十二年
年。 2013-16 年西非埃博拉疫情始于距 KGH 不到 4 小时车程的地方,是
埃博拉病毒首次爆发发生在靠近现有病毒性出血热基础和基础设施的地区
临床研究。 KGH 每年管理多达 600 名疑似拉沙热患者,凯内马和
周边地区出现大量埃博拉病例。 我们将利用这些的现有样本
建立了感染拉沙热或埃博拉病毒的人类群体。 虽然众所周知
无症状或轻度症状感染均发生在拉沙热和埃博拉病毒中,目前尚不清楚哪个宿主
因素决定了暴发性出血热的进展。 同样,拉沙病毒的很大一部分
发烧和埃博拉幸存者会出现大量严重的后遗症,但预示这些的因素
并发症仍然难以捉摸。 我们的研究计划支持拉沙热和埃博拉幸存者群体。
我们建议整合实验方法和计算模型来测试和验证
对拉沙热和埃博拉病毒具有重要意义的假设。 我们的团队拥有良好的合作记录,
拉沙病毒和埃博拉病毒方面的独特专业知识以及适当的多学科代表
系统和计算生物学、病毒学、免疫学、基因组学、蛋白质组学、机器学习、
执行拟议计划所需的统计方法和建模。 我们项目 1 的总体目标是
生成一个综合数据集,可用于构建拉沙热患者结果的预测模型
和埃博拉病毒。 具体目标 1 下提出的研究将定义区分拉沙的生理特征
发烧和埃博拉幸存者和非幸存者,以及出现严重后遗症的个人。 具体目标 2
将阐明埃博拉病毒和拉沙热幸存者成功的抗体网络的进化和功能。 时间
细胞动力学以及人类白细胞抗原在成功清除埃博拉病毒和
拉沙病毒将在具体目标 3 中描述的研究中进行定义。在具体目标 4 中,我们将开发和测试
宿主因素在拉沙热和埃博拉结果中的作用的预测模型。 项目 1 关于宿主因素
补充项目 2 中描述的关于病毒因素的研究,并整合并利用每个
核心。
