NK cell function depends on the balance between inhibitory and activating receptors expressed on the cell surface and how they are organized relative to each other in the NK cell-target cell synapse. For this reason a major goal of the program is to understand the cell biology of human NK cell function. Morphological studies proposed by all four units include localization of NK receptors and ligands in intracellular compartments and examination of their cell surface distribution at the NK cell-target cell synapse. In addition, membrane traffic pathways affecting receptor expression will be defined. All of these cell biological studies involve use of a deconvolution microscope facility to be provided by this Core. To understand the cell biology of individual NK receptors in a controlled context, many of the studies proposed will make use of transfectants produced by introduction of receptors into the NKL cell line or ligands into the 721.221 cell line. In order to produce such transfectants, this Core provides a shared AMAXA Nucleofector instrument. The Core also supports a shared Staff Research Associate (50% effort) who will be supervised by the Director, provide technical assistance for Core utilization and provide training in use of the Core facilities to personnel of the program. The specific aims of this Microscopy and Shared Equipment Core are to 1) support and maintain the deconvolution microscopy facility for the program and 2) purchase, support and maintain an AMAXA Nucleofector.

NK 细胞功能取决于细胞表面表达的抑制性受体和激活性受体之间的平衡，以及它们在 NK 细胞-靶细胞突触中相对于彼此的组织方式。因此，该项目的一个主要目标是了解人类 NK 细胞功能的细胞生物学。所有四个单位提出的形态学研究包括 NK 受体和配体在细胞内区室中的定位，以及检查它们在 NK 细胞-靶细胞突触处的细胞表面分布。此外，还将定义影响受体表达的膜运输途径。所有这些细胞生物学研究都涉及使用该核心提供的反卷积显微镜设施。为了在受控环境下了解单个 NK 受体的细胞生物学，许多提议的研究将利用通过将受体引入 NKL 细胞系或将配体引入 NKL 细胞系而产生的转染子。 721.221细胞系。为了产生此类转染子，该 Core 提供了共享的 AMAXA Nucleofector 仪器。核心还支持一名共享的研究助理（50% 的工作量），该助理将由主任监督，为核心利用提供技术援助，并为项目人员提供使用核心设施的培训。该显微镜和共享设备核心的具体目标是 1) 支持和维护该计划的反卷积显微镜设施，以及 2) 购买、支持和维护 AMAXA Nucleofector。
