NEUROPATHOLOGY CORE – CORE D: PROJECT SUMMARY/ABSTRACT Postmortem examination remains critical to elucidate the etiology in cases of dementia and to confirm the diagnosis of AD, despite recent advances in neuroimaging and fluid biomarkers. Autopsy is also critical for confirming the clinical diagnosis and identifying comorbidities, which are common in older subjects. The Neuropathology Core (Core D) of the Johns Hopkins Alzheimer's Disease Research Center (JHADRC) has three overarching goals. The first is to conduct postmortem neuropathological assessments in subjects enrolled in the JHADRC Clinical Core. Second, to prepare, store, and distribute autopsy brain tissues for research. The third goal is the training of young physicians and neuroscientists in the neuropathology of dementias and neurodegenerative diseases. The specific aims of Core D are as follows: (1) to arrange and perform autopsies on clinically well-characterized subjects enrolled through the JHADRC and assist with consensus diagnoses on JHADRC subjects, (2) to store optimally prepared tissues from the autopsies and to make these specimens available to investigators associated with the JHADRC and at other collaborating institutions, (3) to integrate the neuropathologic data from these cases with the clinical and biomarker data acquired in the same participants, using the JHADRC database, and to submit the neuropathology data to the National Alzheimer's Coordinating Center (NACC), working with the Data Core (4) to support the assessment of genetically engineered mouse models relevant to Alzheimer's disease (AD) and related disorders, and (5) to train basic investigators and clinical neuroscientists in the morphological and diagnostic concepts relevant to AD, to other types of dementias and neurodegenerative disorders (including trainees supported by the REC). In addition, the availability of human brain postmortem tissues has become increasingly important for validating research hypotheses and for investigations and development of biomarkers of AD. Core D will therefore be expanding its postmortem tissue collection to include a large number of specimens from younger subjects (30 to 65 years) suitable to examine the very early stages of AD pathology and its pathogenesis.

神经病理学核心-核心D：项目总结/摘要 尸检对于阐明痴呆病例的病因和确认痴呆的发病机制仍然至关重要。 尽管最近在神经影像学和液体生物标志物方面取得了进展，但AD的诊断仍然存在困难。尸检也很重要， 确认临床诊断并识别老年受试者常见的合并症。的 约翰霍普金斯阿尔茨海默病研究中心（JHADRC）的神经病理学核心（核心D） 三大目标。首先是对受试者进行死后神经病理学评估 在JHADRC临床中心注册。第二，准备，储存和分发尸检脑组织， research.第三个目标是在神经病理学方面培训年轻的医生和神经科学家， 痴呆和神经变性疾病。核心D的具体目标如下：（1）安排和 对通过JHADRC招募的临床特征良好的受试者进行尸检，并协助 对JHADRC受试者的共识诊断，（2）储存最佳制备的尸检组织， 将这些标本提供给与JHADRC和其他合作机构有关的研究人员， 机构，（3）将这些病例的神经病理学数据与临床和生物标志物数据相结合 使用JHADRC数据库，在相同的参与者中获得神经病理学数据，并将神经病理学数据提交给 国家阿尔茨海默氏症协调中心（NACC），与数据核心（4）合作支持评估 与阿尔茨海默病（AD）和相关病症相关的基因工程小鼠模型，和（5） 培训基础研究人员和临床神经科学家的形态学和诊断概念， AD，其他类型的痴呆症和神经退行性疾病（包括REC支持的受训人员）。 此外，人脑死后组织的可用性对于验证 研究假设和研究和开发AD的生物标志物。因此，核心D将 扩大其死后组织收集，包括大量的标本，从年轻的科目（30 至65岁），适合于检查AD病理学的非常早期阶段及其发病机制。
