HISTOPATHOLOGY, IMMUNOHISTOCHEMISTRY, AND IN SITU HYBRIDIZATION SERVICES

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 向中心和外部机构的各种研究人员提供了病理学服务。服务包括常规苏木精-伊红组织学、分子病理学(免疫组织化学和原位杂交)、电子显微镜和组织病理学咨询。为了提高我们的诊断病理学能力，我们系统地评估了针对人类细胞/组织和感染剂的商业可用抗体，以应用于NEPRC中的非人类灵长类物种。抗体被选择用于诊断和/或实验病理学的潜在应用，以及在速冻或福尔马林固定的石蜡包埋组织中的反应性。此外，比较病理学分部每年都会收到多项请求，要求检测抗体并为我们分部的调查人员、其他非传染性疾病控制中心分部和合作的调查人员制定IHC方案。 猴免疫缺陷病毒(SIV)和SIV/HIV嵌合病毒(SHIV)感染亚洲猕猴是研究HIV感染和艾滋病发病机制的重要动物模型。此外，该模型还为评估旨在预防人类感染或艾滋病的疫苗和抗逆转录病毒药物的有效性提供了一个挑战系统。我们设计了几种分子探针，用于定位感染SIV和SIV不同分离株和克隆的猴子组织中的病毒RNA。这些探针被用来测量感染猴子组织中感染细胞的数量和分布。我们也有与其他几种病毒病原体的目标RNA或DNA序列杂交的探针，包括HIV、SRV-1、CMV、SV40、EBV、赛米里疱疹病毒和微小病毒。 病理学支持是一项基本的核心职能，它加强了一些机构和研究人员的群体管理和研究工作。比较病理学分部还对研究人员、技术人员、博士后研究员和研究生进行免疫组织化学方法培训。 艾滋病相关和非艾滋病相关。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Pathology services were provided to a variety of investigators both at the center and from outside institutions. Services included routine hematoxylin and eosin histology, molecular pathology (immunohistochemistry and in situ hybridization), electron microscopy, and histopathology consultation. In order to improve our diagnostic pathology capabilities, we systematically evaluate commercially available antibodies directed against human cells/tissues and infectious agents for application in the nonhuman primate species housed at the NEPRC. Antibodies are selected for potential applications in diagnostic and/or experimental pathology, and for reactivity in either snap-frozen or formalin-fixed, paraffin-embedded tissues. In addition, the Division of Comparative Pathology receives multiple requests each year to test antibodies and develop IHC protocols for investigators in our Division, other NEPRC Divisions, and collaborating investigators. The infection of Asian macaque monkeys with simian immunodeficiency virus (SIV) and SIV/HIV chimeric viruses (SHIVs) serves as an important animal model for studying the pathogenesis of HIV infection and AIDS. In addition, this model provides a challenge system for evaluating the efficacy of vaccines and antiretroviral agents designed to prevent infection or AIDS in humans. We have designed several molecular probes for localizing viral RNA in tissues of monkeys infected with various isolates and clones of SIV and SHIV. These probes are used to measure the quantity and distribution of infected cells in the tissues of infected monkeys. We also have probes that hybridize with target RNA or DNA sequences of several other viral pathogens, including HIV, SRV-1, CMV, SV40, EBV, Herpes saimiri, and parvovirus. Pathology support is an essential core function that enhances colony management and research efforts by a number of institutions and investigators. The Division of Comparative Pathology also trains investigators, technicians, postdoctoral fellows and graduate students in immunohistochemistry methods. AIDS related and non-AIDS related.
