摘要:: Blood from patients with hairy cell leukaemia (HCL) was used to investigate subpopulations of the non-specific activated lymphocyte killer (ALK) cells generated in mixed lymphocyte culture (MLC). Mononuclear cells from four of five patients with HCL had decreased natural killer (NK) cell activity and, of these, all showed a decrease in ALK cell activity against K-562 target cells (NK like cells), but three had normal levels of ALK cells able to kill melanoma cells. One patient who had received splenectomy had normal NK cell activity, and in MLC his cells generated normal levels of both subpopulations of ALK cells. The results support the hypothesis of separate subsets of ALK cells: NK like cells with NK cell precursors and which preferentially lyse the K-562 target cell and a second separate population which arises independent of NK cell precursors and which has strong cytolytic activity against an NK insensitive melanoma cell line.
