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.
项目摘要 /摘要
塞拉利昂东部省的发病率是世界上最高的发病率。成员
研究小组一直在Kenema政府医院(KGH)开展Lassa Fever超过十二
年。 2013 - 16年西非埃博拉病毒的流行病距离KGH不到四个小时,是
第一次发生的埃博拉疫情发生在靠近现有的病毒出血热和
临床研究。 KGH每年最多管理600名疑似Lassa发烧患者,以及Kenema和
周围地区经历了大量埃博拉病例。我们将利用这些样本
已建立了感染Lassa Fever或埃博拉病毒的人群。虽然已经确定了
在Lassa热和埃博拉病毒中,无症状或轻度症状感染OCUR,尚不清楚哪个宿主
因素确定了暴发性出血热的发展。同样,大部分拉萨
发烧和埃博拉冲浪者会出现众多严重的后遗症,但鉴于这些的因素
并发症仍然难以捉摸。我们的研究计划支持LASSA热和埃博拉幸存者群体。
我们建议将实验方法和计算建模集成以测试和验证
对Lassa热和埃博拉病毒的明显假设。我们的集会团队有合作的记录,
LASSA病毒和埃博拉病毒的独特专业知识以及适当的多学科表示
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,
执行提出的程序所需的统计方法和建模。我们在项目1中的总体目标是
生成一个集成的数据集,该数据集可用于建立LASSA Fever中患者结局的预测模型
和埃博拉病毒。根据特定目标1提出的研究将定义区分LASSA的生理属性
发烧和埃博拉冲浪者和非活生生,以及产生严重后遗症的个体。特定目标2
将阐明在埃博拉病毒和LASSA热幸存者中成功的抗体网络的演变和功能。 t
细胞动力学和人类白细胞抗原的作用,导致成功清除埃博拉病毒和
LASSA病毒将在特定目标3中描述的研究中定义。在特定目标4中,我们将开发和测试
宿主因子在LASSA热和埃博拉病毒结局中的作用的预测模型。关于宿主因素的项目1
完成项目2中描述的有关病毒因素的研究,并与并利用每一个
内核。
