组织学核心将为以下组织样本的组织学和免疫学染色提供支持： 项目1-4。将适当制备的组织包埋在石蜡或OCT中进行切片， 染色将进行常规组织学染色。免疫组化染色可采用单色或双色， 用ABC法进行。对于免疫荧光，将对固定或冷冻切片进行染色 通过针对白细胞群体的谱系特异性标志物的Ab，或表面共刺激分子， 粘附分子、受体和细胞因子。将进行最多4种颜色的免疫荧光染色 用于共聚焦显微镜分析。组织学核心还将开发用于研究效应器的新试剂 细胞功能和病毒感染过程中的发展，并与流式细胞术核心密切合作， 定义病毒感染过程中白细胞的Ab染色条件和标志物表达。的使用 核心由4个项目如下： 项目1：小鼠肺和淋巴结组织的炎症染色、浸润细胞群和 CD 8 + T细胞、NK细胞、树突状细胞和其他细胞因子和表面受体的表达 造血细胞在流感病毒感染过程中。 项目2：小鼠肝细胞浸润白细胞群及其Ag表达的染色， 腺病毒感染期间细胞因子的产生;阻断CD 8 + T细胞与NK相互作用的试剂 细胞、树突状细胞和其他细胞类型将由核心开发。 项目3：脾脏切片染色，用于浸润细胞、细胞因子产生和CD 8 + T细胞与 NK细胞和树突状细胞在MCMV感染的易感和耐药小鼠品系。 项目4：小鼠肺和淋巴组织浸润白细胞亚群，表面分子， 和细胞因子以及阻断CD 8 + T细胞与辅助细胞的相互作用。 核心的长期目标是为获得CD 8+的免疫学信息提供支持 病毒感染中效应细胞的发育和功能以及其他细胞类型对CD 8 + T细胞的影响 功能协调发展的

The Histology Core will provide support for histological and immunological staining of tissue samples from Projects 1-4. Appropriately prepared tissues will be embedded in paraffin or OCT for sectioning and staining. Routine histological stains will be performed. Single or 2-color immunohistochemical staining will be performed with the ABC method. For immunofluorescence, either fixed or frozen sections will be stained by Ab against lineage-specific markers for leukocyte populations, or surface costimulation molecules, adhesion molecules, receptors, and cytokines. Up to 4 color immunoflourescence staining will be performed for confocal microscopy analysis. The Histology core will also develop new reagents for studying effector cell function and development during virus infections and work closely with the Flow Cytometry Core to define Ab staining conditions and marker expression by leukocytes during virus infection. The usage of the core by the 4 projects are as follows: Project 1: Staining of mouse lung and lymph node tissues for inflammation, infiltrating cell population, and the expression of cytokine and surface receptors by CD8+ T cells, NK cells, dendritic cells, and other hematopoietic cells during influenza virus infection. Project 2: Staining of mouse liver cells for infiltrating leukocyte populations and their Ag expression and cytokine production during adenovirus infection; Reagents to block the interaction of CD8+ T cells with NK cells, dendritic cells and other cell types will be developed by the Core. Project 3: Spleen sections staining for infiltrating cells, cytokine production, and CD8+ T cell interaction with NK cells and dendritic cells during MCMV infection in susceptible and resistant mouse strains. Project 4: Staining of mouse lung and lymphoid tissues for infiltrating leukocyte subsets, surface molecules, and cytokines during influenza infection and blocking of CD8+ T cell interaction with accessory cells. The long term aim of the core is to provide support for the acquisition of immunological information on CD8+ effector cell development and function in viral infections and the influences of other cell types on CD8+ T cell functions.
