In Natural Killer Cell Protocols: Cellular and Molecular Methods, Kerry S. Campbell and Marco Colonna have assembled a comprehensive collection of readily reproducible methods designed to study natural killer (NK) cells from the broadest variety of viewpoints. These include not only classic techniques, but also new approaches to standard methods, newly evolved techniques that have become valuable for specific applications, and unique models for manipulating and studying NK cells. Among the advanced methods covered are those for in vitro transendothelial migration, in vivo detection of cells migrating into tumors, immunofluorescence staining of intracellular cytokines, and in vitro NK cell development. Valuable techniques for specific applications include vaccinia virus protein expression, soluble KIR-Fc fusions for HLA class I binding assays, calcium mobilization in cell conjugates, and identification of heterodimeric receptor complexes using cDNA library expression cloning. No less important are accounts of such classic methods as hybrid resistance, ADCC, viral defense, target cell cytotoxicity assays, cloning and culturing, tumor immunotherapy, and generation of HLA class I transfected target cells. Natural Killer Cell Protocols: Cellular and Molecular Methods offers immunologists, cancer researchers, virologists, and cell biologists today's most comprehensive collection of both established and cutting-edge techniques, methods that will contribute significantly to advancing our understanding of this fascinating and critically important class of cells.
