Inhibition of bone marrow colony formation by human natural killer cells and by natural killer cell-derived colony-inhibiting activity
Incubation of human peripheral blood lymphocytes with bone marrow cells resulted in significant inhibition of colony formation by committed myeloid and erythroid cells. Using positively selected homogeneous natural killer (NK) cell preparations and lymphocyte subpopulations depleted of or enriched for NK cells, we definitively characterize as NK cells the cells in normal peripheral blood that a...
متن کاملInhibition of natural killer cell activity by a soluble substance released by rat peritoneal cells.
We describe here a soluble substance released by nonadherent cells from the peritoneal cavity of W/Fu rats that markedly inhibits the activity of mouse, rat, and human natural killer (NK) cells. The NK-inhibiting substance (NK-IS) has low molecular weight (less than 1000), is heat resistant (100 degrees for 15 min), and is insensitive to nonspecific proteases. NK-IS is produced in the presence ...
متن کاملInhibition of Natural Killer Cell Activity by a Soluble Substance Released by Rat Peritoneal Cells1
We describe here a soluble substance released by nonadherent cells from the peritoneal cavity of W/Fu rats that markedly inhibits the activity of mouse, rat, and human natural killer (NK) cells. The NK-inhibiting substance (NK-IS) has low molecular weight (<1000), is heat resistant (100° for 15 min), and is insensitive to nonspecific proteases. NK-IS is produced in the presence of indomethacin...
متن کاملSelective inhibition by alcohol and cortisol of natural killer cell activity of lymphocytes from cord blood.
1. The immunosuppressive effects of drugs such as alcohol or hormones such as cortisol may be age-related. To test this hypothesis, the authors investigated the in vitro effects of ethanol (EtOH) and cortisol on Natural Killer (NK) cell activity of lymphocytes from normal cord blood in comparison with that of lymphocytes from normal adult peripheral blood. 2. K562, an erythroleukemia cell line,...
متن کاملInhibition of pulmonary metastases and enhancement of natural killer cell activity by methionine-enkephalin.
Studies were performed to investigate the effects of the endogenous opioid peptide methionine enkephalin on experimental metastasis of the murine B-16 melanoma and on murine splenic natural killer cell activity. Methionine enkephalin was shown to significantly inhibit tumor metastasis and significantly enhance splenic natural killer cell activity. These results indicate that the endogenous opio...
