中文摘要
项目总结:
目前对动物免疫病毒的研究对于进一步了解包括病毒在内的动物免疫疾病的基本发病机制是至关重要的。
与人类丙型肝炎病毒相关的两种病毒的起源和致病机制。在这项新的提案中,将不再讨论两种马丙型肝炎病毒。
研究目的:阐明病毒性肝炎的发病机制,阐明免疫调节系统在病毒性肝炎发病机制中的重要作用。
通关。他们的工作。
非灵长类丙型肝炎病毒(NPHV)是丙型肝炎病毒最接近的近亲,马和猪是最主要的。
主持人:马体内的NPHV基因与人类体内的丙型肝炎病毒之间有许多相似之处尚未得到证实。
包括肝脏的趋向性,导致持续的人类感染的能力下降,以及免疫应答的延迟发病时间也不谋而合。
随着肝脏酶活性的轻微增加,不同的分离株之间存在着相对较大的多样性差异。
马细小病毒肝炎病毒(EqPV-H)是最近在一匹马身上发现的,患有丙型肝炎的血清也是如此。
该病被称为泰勒氏病,目前被认为是该病的主要原因。初步的临床数据显示。
展示马的EqPV-üH病毒与人类的细小病毒B19病毒之间的多个相似之处,包括高。
在一些临床上健康的人中,发病率很低,但有一些重要的疾病关联与暴发型肝炎的巧合。
随着血清转换率的提高,血液和组织中的血液和组织多年来一直坚持不懈。
他们的具体目标是开发新的分子生物学和细胞生物学系统,以研究病毒的中和、进入和传播。
复制、复制和控制病毒的生产,以及为防止病毒传播和传播的措施做出贡献的目标之一。
对这三种新型非病毒性肝炎药物的分子生物学和病毒学研究有了更深入的了解。
马体内携带NPHV病毒和EqPV-h病毒的感染将被用来进一步阐明它们的趋向性、过程和转归。
感染、免疫系统反应、疾病和病理。这些研究的主要发现加在一起,可能会导致癌症的发生。
转变对甲型病毒性肝炎主要致病机制的认识,为临床治疗提供一种新的模式和系统的方法。
疫苗和/或治疗药物的开发、开发和创新将彻底改变兽医和医疗技术的实践,从而进一步降低死亡率。
从马身上消除泰勒氏肺病。
该委员会建议,这些研究将利用考生作为一名大型动物内科医生的独特专业资格。
位于中国兽医教学中心和研究机构之间的专科医生。他们的职业发展计划将不包括。
来自一支由20名高度合格的中国人组成的团队的指导,以及在体外和体内移植的具体技术方面的培训。
通过北京大学,病毒学和免疫学、医学和更广泛的医学接触将扩大到医学病毒学和免疫学研究的两个领域。
课程、研讨会和俱乐部杂志。这位候选人打算为进一步的联邦政府资助提交更多的拨款。
包括在第二个年中发布R21版本或R03版本,在第二个年末发布版本R01版本,这将为我们实现这一目标提供服务。
独立性。这项工作将使这位候选人能够在马和肝病研究和病毒传播领域发展一个新的利基市场。
病因学表示,这将有助于她进入一名高级学术和教职员工的职业生涯,成为一名高级兽医和临床医生兼研究员。
英文摘要
PROJECT SUMMARY
The study of animal viruses has been critical for understanding basic disease mechanisms, including
the origin and pathogenesis of related human viruses. In this proposal, two equine hepatitis viruses will be
studied to elucidate mechanisms of viral hepatitis and the role of the immune system in pathology and viral
clearance.
Non-primate hepacivirus (NPHV) is the closest relative of hepatitis C virus, and horses are the primary
host. A number of similarities between NPHV in horses and HCV in humans have been demonstrated,
including liver tropism, the ability to cause persistent infection, delayed onset of immune responses coinciding
with mildly increased liver enzymes, and a relatively large diversity among isolates.
Equine Parvovirus-Hepatitis (EqPV-H) was recently discovered in a horse with serum hepatitis, also
known as Theiler’s disease, and is currently considered the cause of that disease. Preliminary data
demonstrate multiple similarities between EqPV-H in horses and parvovirus B19 in humans, including high
prevalence in clinically healthy individuals, rare but important associations with fulminant hepatitis coincident
with seroconversion, and persistence in the serum and tissues for years.
Specific aims are to develop molecular and cell-based systems to study virus neutralization, entry,
replication, and virion production, with the goals of contributing to measures preventing transmission and
obtaining a deeper understanding of the molecular virology of these new viral hepatitis agents. In parallel, in
vivo infections with NPHV and EqPV-H in horses will be used to elucidate their tropism, course and outcome of
infection, immune responses, and pathology. Together, the findings of these studies have the potential to
transform our understanding of the pathogenic mechanisms of viral hepatitis, to provide a model system for
vaccine and/or therapeutic development, and to revolutionize veterinary medical practices to reduce or
eliminate Theiler’s disease from horses.
The proposed studies utilize the candidate’s unique qualifications as a Large Animal Internal Medicine
specialist situated within a veterinary teaching and research institution. Career development plans will include
mentoring from a team of highly qualified individuals, training in specific techniques of both in vitro and in vivo
virology and immunology, and broader exposure to the fields of virology and immunology through University
classes, seminars and journal clubs. The candidate intends to submit grants for further federal funding,
including an R21 or R03 in the second year and an R01 in the final year, which will serve to achieve
independence. This work will allow the candidate to develop a niche in equine hepatology and viral
pathogenesis that will serve to launch her into an academic faculty career as a veterinary clinician researcher.
