项目摘要
The PI, Mark S. Kindy, Ph.D., has been studying the mechanisms and pathways associated with a number of
neurological and neurodegenerative disorders. These include, Alzheimer’s disease (AD), stroke, Parkinson’s
disease (PD), traumatic brain injury (TBI), chronic traumatic encephalopathy (CTE), spinal cord injury (SCI),
among others. All of these disorders are afflictions that are present in the VA population and contribute
significantly to the overall health of the Veterans. The overarching goal is to understand the mechanisms
involved in the disease processes and to develop therapeutic approaches to treat them. I have three basic areas
of research that we focus on. The first program is centered around stroke and the impact of negative vascular
health factors (such as: obesity, diabetes, age, salt sensitivity hyperlipidemia, and hypertensivity) on the
induction of reactive oxygen species (ROS) production and activation of the inflammation (inflammasome). We
have shown that aged animals with the risk factors have worse outcomes and recovery is exacerbated due to
the presence of both systemic and neuroinflammation. The generation of better clinical models of stroke to test
these risk factors and health disparities following injury. Studies using low-density lipoprotein receptor (ldlr)
deficient mice with and without high fat diet are being used to study the impact of oxidized phospholipids (OxPLs)
on stroke outcomes. Mice expressing OxPL antibodies will be tested for protection from stroke. Finally, we are
examining the impact of chronic kidney disease, left ventricular hypertrophy and FGF23 on stroke and stroke
outcomes. Mice with targeted deletion of the fgfr4 gene or overexpression of the FGF23 are being examined for
stroke outcomes. These studies will better capture the true nature of veterans and civilians who have a stroke
and provide a better approach to treating the disease. A second line of research focuses on the role of serum
amyloid A (SAA) proteins in the pathogenesis of stroke. Recent studies have implicated SAAs in innate immunity
and various disorders, however the precise mechanism eludes us. SAAs are elevated following stroke (cerebral
ischemia) and TBI, and our studies show that SAA increases the cytokine interleukin-1 (IL-1), which is
mediated by Nod-like receptor protein 3 (NLRP3) inflammasome, cathepsin B and caspase-1 and may play a
role in the pathogenesis of neurological disorders. Using transgenic and gene deleted mice as well as AAV
expressing constructs we are evaluating the impact of SAA on stroke and other neurological diseases. Another
line of research focuses on serum amyloid P component (SAP), which is found in all amyloids and studies have
suggested that it plays an integral role in the formation, progression, and maintenance of the amyloid disease
processes. The amyloid diseases include: AD, PD (tau, -synuclein, TDP-43), tauopathies, CTE, ALS (SOD1,
TDP-43, C9ORF72), systemic amyloids (AA, TTR, amylin), Huntington’s disease (HD), ABri and ADan.
Inflammation modifies SAP function, and inflammatory signaling pathways impair cognitive function in vivo. Our
long-term goal is to determine the mechanisms regulating SAP function, particularly within the setting of AD and
inflammatory diseases. Consequently, the objective of this grant is to characterize the role for SAP in
inflammation and AD. We have developed and amassed various transgenic and gene deleted mice as well as
viruses and inhibitors to determine the impact of SAP in the amyloid diseases. Since both SAA and SAP are
produced mainly in the liver, we are working with Ionis Pharmaceuticals in the design and testing of antisense
oligonucleotides (ASOs) as therapeutic approaches to these disorders. In addition, we are working with
clinicians at the Haley VA and other VAs (Boston CTE Center) and Universities around the US to correlate the
animal studies with human disease. Using autopsy tissues, blood, CSF and other reagents to validate the studies
in our mouse and rat models. This is critical to our basic understanding of the disease process and in the
development of therapeutics for treatment.
PI,Mark S.Kindy博士,一直在研究与许多
神经和神经退行性疾病。这些疾病包括阿尔茨海默病(AD)、中风、帕金森氏症
疾病(PD)、创伤性脑损伤(TBI)、慢性创伤性脑病(CTE)、脊髓损伤(SCI)、
还有其他的。所有这些疾病都是退伍军人群体中存在的痛苦,并导致
对退伍军人的整体健康有重大影响。最重要的目标是了解这些机制
参与疾病过程,并开发治疗方法。我有三个基本领域
我们所关注的研究。第一个方案以中风和负面血管的影响为中心
健康因素(如肥胖、糖尿病、年龄、盐敏性高脂血症和高血压)
诱导活性氧簇(ROS)的产生并激活炎症(炎症体)。我们
已经表明,有风险因素的老年动物预后较差,由于以下原因,康复加剧
全身性和神经性炎症的存在。建立更好的卒中临床模型进行检验
这些危险因素和受伤后的健康差距。低密度脂蛋白受体(LDLR)的研究
用高脂饮食和不高脂饮食缺乏的小鼠来研究氧化磷脂(Oxpls)的影响。
对中风结果的影响。表达OxPL抗体的小鼠将接受中风保护测试。最后,我们是
检测慢性肾脏疾病、左室肥厚和FGF23对卒中和卒中的影响
结果。靶向缺失FGFR4基因或FGF23过度表达的小鼠正在接受检查
中风的结果。这些研究将更好地捕捉中风退伍军人和平民的真实本质
为治疗这种疾病提供了一种更好的方法。第二条研究重点是血清的作用。
淀粉样蛋白A(SAA)在中风发病机制中的作用最近的研究表明SaaS与先天免疫有关
和各种疾病,然而,确切的机制我们难以捉摸。中风后SaaS升高(脑部
缺血)和脑损伤,我们的研究表明,山梨醇能增加细胞因子白细胞介素1(IL-1),这是
由NLRP3炎症体、组织蛋白酶B和caspase-1介导,可能在
在神经性疾病的发病机制中的作用。利用转基因和基因缺失的小鼠以及AAV
通过表达结构,我们正在评估SAA对中风和其他神经疾病的影响。另一个
一系列研究集中在血清淀粉样蛋白P成分(SAP),它在所有淀粉样蛋白中都存在,研究已经
提示它在淀粉样变性的形成、发展和维持中起着不可或缺的作用。
流程。淀粉样变性疾病包括:AD,PD(tau,-synuclein,Tdp-43),tauopy,CTE,ALS(SOD1,
TDP-43、C9ORF72)、系统性淀粉样蛋白(AA、TTR、淀粉蛋白)、亨廷顿病(HD)、ABRI和Adan。
炎症改变SAP的功能,炎症信号通路损害体内的认知功能。我们的
长期目标是确定调节SAP功能的机制,特别是在AD和
炎症性疾病。因此,这笔赠款的目标是确定SAP在
炎症和AD。我们已经培育和积累了各种转基因和基因缺失的小鼠以及
病毒和抑制剂,以确定SAP在淀粉样疾病中的影响。由于SAA和SAP都是
主要在肝脏生产,我们正在与Ionis制药公司合作设计和测试反义
寡核苷酸(ASO)作为治疗这些疾病的方法。此外,我们正在与
退伍军人事务部和其他退伍军人管理局(波士顿CTE中心)和美国各地大学的临床医生将
与人类疾病相关的动物研究。使用尸检组织、血液、脑脊液和其他试剂来验证研究
在我们的小鼠和大鼠模型中。这对于我们对疾病过程的基本理解以及在
治疗疗法的发展。
