DESCRIPTION (provided by applicant): The etiology of Parkinson's disease is multivariate, ranging from identified genetic mutations to strict environmental causation. One environmental agent that has been shown to induce Parkinsonism is virus, including influenza. Our lab, and others, has shown that the highly pathogenic avian influenza virus, H5N1, is neurotropic and can induce a number of Parkinsonism pathologies including loss of the DA phenotype in DA neurons, increased activation of the immune system and increased phosphorylation and aggregation of alpha- synuclein. What is unknown, at this time, is whether the induced Parkinsonian pathologies that we observed are specific to only certain strains of influenza (those known to be neurotropic (H5N1)), or can also be induced by those that do not enter the CNS, including the 1918-H1N1 influenza virus that was responsible for the Spanish flu and has been implicated in von Economo's encephalopathy and the H1N1 influenza virus strain (A/H1N1/CA/04/2009) most responsible for the 2009 pandemic. We also seek to determine the critical gene(s) responsible for influenza neurotropism. In this application, we propose 3 specific aims to investigate the role of influenza in neurodegenerative disease, concentrating on pathologies observed in Parkinson's disease. These are: 1) Identify strains of Type A Influenza that are/are not neurotropic, and identify the gene(s) within the influenza genome that confer neurotropism, 2) Determine the immune response in brain initiated by neurotropic and non-neurotropic influenza viruses, and 3) Determine if the parkinsonian pathologies induced by the H5N1 Type A Influenza virus are common to other Type A influenza viruses. The results of these studies, which utilize a unique series of chimeric influenza viruses generated between the neurotropic H5N1 and 1918-H1N1and 2009 H1N1 influenza viruses, will allow us to identify the key components within the virus that allow entry into the nervous system and understand how peripheral infection can signal activation of the immune response in brain. In terms of human health, these studies will allow us to predict how current (i.e. H5N1 and H1N1) and future emerging influenza strains will impact the CNS; as well as identify targets (both known and unknown) that allow for development of therapeutic agents to interfere with these processes.

描述(由申请人提供)：帕金森氏病的病因是多元的，从已确定的基因突变到严格的环境原因。已被证明能诱发帕金森氏症的一种环境因素是病毒，包括流感。我们的实验室和其他实验室已经证明，高致病性禽流感病毒H5N1是嗜神经性的，可以诱导许多帕金森病病理，包括DA神经元中DA表型的丧失，免疫系统的激活，以及α-突触核蛋白的磷酸化和聚集增加。目前尚不清楚的是，我们观察到的诱导帕金森病病理是仅针对某些流感毒株(已知的嗜神经性(H5N1))，还是也可由未进入中枢系统的流感病毒诱导，包括导致西班牙流感并与冯·伊科诺莫脑病有关的1918-H1N1流感病毒和导致2009年大流行的H1N1流感病毒株(A/H1N1/CA/04/2009)。我们还试图确定导致流感嗜神经性的关键基因(S)。在本申请中，我们提出了3个具体的 目的是研究流感在神经退行性疾病中的作用，集中在帕金森病的病理观察上。它们是：1)鉴定嗜神经性/非嗜神经性的甲型流感毒株，并鉴定流感基因组中具有嗜神经性的基因(S)，2)确定嗜神经性和非嗜神经性流感病毒在大脑中引发的免疫反应，以及3)确定H5N1甲型流感病毒诱导的帕金森病理是否与其他甲型流感病毒相同。这些研究利用了在嗜神经性H5N1和1918-H1N1以及2009年H1N1流感病毒之间产生的一系列独特的嵌合流感病毒，将使我们能够识别病毒中允许进入神经系统的关键成分，并了解外周感染如何发出激活大脑免疫反应的信号。在人类健康方面，这些研究将使我们能够预测当前(即H5N1和H1N1)和未来新出现的流感病毒株将如何影响中枢神经系统；以及确定允许开发干预这些过程的治疗剂的目标(已知和未知)。
