pubmed:abstractText |
Populations of interleukin 3 (IL 3)-dependent cells can be derived from mouse bone marrow that display natural cytotoxicity (NC) against Wehi-164 target cells but do not display natural killing against YAC-1 cells. These bone marrow-derived NC cells cultured up to 2 mo in IL 3 do not contain rearranged T cell receptor beta-chain genes. They appear to be mast-like cells by electron microscopy and contain heterogeneous type granules. The molecules that mediate NC appear to be contained in these granules and are preformed because protein synthesis inhibitors have no effect on the capacity of IL 3-dependent NC cells to lyse Wehi-164 target cells. In addition to the IL 3-dependent bone marrow-derived cells, the basophilic leukemia cells, RBL-1, but not P815 mastocytoma cells were found to mediate NC against Wehi-164 cells. Both bone marrow-derived NC and RBL-1 cells can lyse L929 cells in 18 hr, suggesting that the putative NC mediator may be related to lymphotoxin/tumor necrosis factor (TNF). Recombinant human TNF displayed identical properties as NC cells; both entities possessed the same target cell specificity and had similar kinetics of target cell killing. The use of polyclonal rabbit antimouse TNF antibody blocked the actions of NC cells. Thus we believe that the mediation of NC is through the actions of a TNF-like molecule.
