DESCRIPTION (provided by applicant): This is an application for a K23 award for Dr. Suzee Lee, a behavioral neurologist at the University of California, San Francisco (UCSF). Dr. Lee is establishing herself as a young investigator in patient-oriented clinical research of neurodegenerative disorders. This K23 award will provide Dr. Lee with the support necessary to accomplish the following goals: (1) to become an expert at patient-oriented clinical research in frontotemporal dementia (FTD); (2) to conduct clinical investigations of presymptomatic carriers of genes implicated in FTD; (3) to implement novel and advanced neuroimaging techniques in clinical studies; and (4) to develop an independent clinical research career. To achieve these goals, Dr. Lee has assembled a mentoring team comprised of two co-primary mentors. Dr. Bruce Miller, clinical director of the UCSF Memory and Aging Center (MAC), directs a program project grant on FTD (FTD-PPG) and a Hillblom Aging Network grant to study normal aging. Dr. William Seeley, director the UCSF MAC Autopsy Program and the Neuropathology Core, conducts neuroimaging studies on selective vulnerability in neurodegenerative diseases to explore early-stage disease pathogenesis. The mentoring team also includes two collaborators: Dr. Maria-Luisa Gorno-Tempini, a neurologist who focuses on neuroimaging in primary progressive aphasia and Dr. John Neuhaus, a statistician, who is an expert in study design and biostatistical analysis. Early diagnosis of front temporal dementia is notoriously challenging. Dr. Lee's research will focus on detecting vulnerable brain networks in presymptomatic carriers of FTD gene mutations (Aims 1 and 2). Dr. Lee will use the existing infrastructure and subject cohorts of the FTD-PPG and Hillblom Aging Network to study 50 unaffected family members of probands with FTD to determine the effect of FTD-related genes on alterations in large-scale structural and functional connectivity neural networks. This research will be the first step in a series of investigations that will aid the longitudinal characterization of the natural history of FTD from its earliest stages, paving the way for the field to establish disease monitoring strategies and time points for future treatments in gene mutation carriers. PUBLIC HEALTH RELEVANCE: Improved understanding of when and where in the brain neurodegeneration begins in presymptomatic carriers of front temporal dementia genes are critical to early diagnosis and disease-monitoring. Characterizing the history of front temporal dementia in this way will be crucial for the successful implementation of future treatments of this disease.

描述（由申请人提供）：这是一份K23奖的申请书，申请人是加州大学旧金山分校弗朗西斯科（UCSF）的行为神经学家苏西·李博士。李博士正在建立自己作为一个年轻的研究者在以病人为导向的神经退行性疾病的临床研究。这项K23奖将为Lee博士提供必要的支持，以实现以下目标：（1）成为以患者为导向的额颞叶痴呆（FTD）临床研究专家;（2）对FTD相关基因的症状前携带者进行临床研究;（3）在临床研究中实施新颖和先进的神经影像学技术;（4）在临床研究中使用神经影像学技术。（4）发展独立的临床研究事业。为了实现这些目标，李博士组建了一个由两名共同主要导师组成的指导团队。加州大学旧金山分校记忆和衰老中心（MAC）的临床主任布鲁斯米勒博士指导了一项关于FTD（FTD-PPG）的项目资助和一项希尔布卢姆衰老网络资助，以研究正常衰老。威廉塞利博士，主任加州大学旧金山分校MAC尸检计划和神经病理学核心，进行神经影像学研究的选择性脆弱性神经退行性疾病，以探讨早期疾病的发病机制。指导团队还包括两名合作者：Maria-Luisa Gorno-Tempini博士，一位专注于原发性进行性失语症神经影像学的神经学家和John Neuhaus博士，一位统计学家，他是研究设计和生物统计分析的专家。 前颞叶痴呆的早期诊断是众所周知的挑战。Lee博士的研究将集中在检测FTD基因突变的前驱携带者中脆弱的大脑网络（目的1和2）。Lee博士将利用FTD-PPG和Hillblom老龄化网络的现有基础设施和受试者队列研究FTD先证者的50名未受影响的家庭成员，以确定FTD相关基因对大规模结构和功能连接神经网络改变的影响。这项研究将是一系列研究的第一步，这些研究将有助于从最早阶段纵向表征FTD的自然史，为该领域建立疾病监测策略和基因突变携带者未来治疗的时间点铺平道路。 公共卫生关系：提高对前颞叶痴呆基因的症状前携带者大脑神经变性开始的时间和地点的理解对于早期诊断和疾病监测至关重要。以这种方式描述前颞叶痴呆的历史对于成功实施这种疾病的未来治疗至关重要。
