As part of the strategy for screening for natural killer (NK) cell-specific monoclonal antibodies (MoAb) we have raised a number of murine NK-like cell lines in media containing interleukin-2 (IL-2). The detection of specific NK cell alloantigens on a C57BL/6 cell line in long-term culture in IL-2 is the subject of this paper. The C57BL/6 cell line has the morphology of large granular lymphocytes (LGL) and exhibits strong cytolytic activity against the archetype NK cell target, YAC-1. Absorption of three anti-NK antiserum, NZB anti-BALB/c (anti-NK-2.1), BALB/c anti-DBA/2 (anti-NK-3.1) and CE anti-CBA (anti-NK-4.1), with the C57BL/6 cell line removed the anti-NK activity from these antisera. Flow cytometric studies of the C57BL/6 cell line demonstrated significant binding of the anti-NK-1.1 MoAb produced by hybridoma PK136. Our results suggest that the C57BL/6 NK-like cell line exhibits some of the properties of naive NK cells and expresses all the known NK cell-specific alloantigens, NK-1.1, NK-2.1, NK-3.1 and NK-4.1 and therefore is potentially useful in selecting NK specific hybridomas and in studying the biology of NK cells.

UI MeSH Term Description Entries
D007519 Isoantigens Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. Alloantigens,Alloantigen,Isoantigen
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
