Abstract Granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) each bind specifically to a small number of high- affinity receptors present on the surface of the cells of the acute myelogenous leukemia line, KG-1. Through chemical cross-linking of IL-3 and GM-CSF to KG-1 cells, we identified distinct binding proteins for each of these cytokines with approximate molecular masses of 69 and 93 Kd, respectively. Although these two binding proteins are distinct, GM- CSF and IL-3 compete with each other for binding to KG-1 cells. Other cell lines, which express receptors for either factor but not for both do not display this cross-competition for binding with IL-3 and GM-CSF. These findings imply that distinct IL-3 and GM-CSF binding proteins are expressed on the cell surface and that an association exists between these proteins on KG-1 cells.

Abstract We have evaluated the therapeutic activity of recombinant erythropoietin (rEpo), in comparison with recombinant interleukin-3 (rIL-3) and granulocyte-macrophage colony-stimulating factor (rGM-CSF), on a lethal form of acute anemia resulting from Fc gamma receptor- mediated erythrophagocytosis after a single injection (500 micrograms) of a monoclonal anti-mouse red blood cell (MRBC) autoantibody. Continuous perfusion of rEpo before the administration of anti-MRBC monoclonal antibody completely protected animals from death due to anemia with a rapid recovery, while no protection was obtained by rIL-3 perfusion. In contrast, rGM-CSF perfusion markedly accelerated the progression of anemia and the mortality rate. This was found to result from an enhancement of erythrophagocytosis by Kupffer cells and by polymorphonuclear leukocytes that massively infiltrated the livers. Even after the injection of a sublethal dose (100 micrograms) of anti- MRBC monoclonal antibody, rGM-CSF-perfused mice died of a severe form of acute anemia. Furthermore, we have shown that rEpo was able to treat efficiently a spontaneous form of autoimmune hemolytic anemia in a majority of anemic NZB mice, whereas rGM-CSF markedly aggravated anemia. This may be of clinical importance, because GM-CSF administration could exhibit an adverse effect in some autoimmune diseases that involve autoimmune anemia.
