We successfully treated 3 consecutive patients who had nonneutropenic rhinocerebral zygomycosis, by use of subcutaneous granulocyte-macrophage colony-stimulating factor therapy combined with traditional surgical and medical treatment. All patients are currently free of disease. Granulocyte-macrophage colony-stimulating factor should be considered as adjuvant therapy for rhinocerebral zygomycosi...

Highly purified murine granulocyte-macrophage progenitor cells (CFU-GM) were used as target cells to assess the possible direct effects of purified preparations of recombinant murine 7-intcrferon, prostaglandin E, recombinant human heavy chain (acidic) ferritin, and recombinant human tumor necrosis factor a (TNF-a) on progenitor cells in vitro. Target CFU-GM, with cloning efficiencies of up to ...

Recombinant (r) and natural human (h) macrophage colony-stimulating factor (M-CSF, CSF-1) have been considered poor stimulators of macrophage progenitor cells present in human marrow, although they are potent stimulators of these cells in mouse marrow. We compared the growth characteristics of rhM-CSF-responsive human macrophage progenitor cells placed in semisolid agarose or agar culture mediu...

We have extended the study of the effects of antisense oligodeoxynucleotides on hematopoietic colony formation to include the effects of antisense to granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), and macrophage colony-stimulating factor (M-CSF) on bone marrow cultures. GM-CSF antisense and GM-CSF receptor antisense cause an increase in...

We have extended the study of the effects of antisense oligodeoxynucleotides on hematopoietic colony formation to include the effects of antisense to granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), and macrophage colony-stimulating factor (M-CSF) on bone marrow cultures. GM-CSF antisense and GM-CSF receptor antisense cause an increase in...

Recombinant murine granulocyte macrophage colony-stimulating factor (rGM-CSF) has been produced in Escherichia coli and purified to homogeneity. GM-CSF has an established role as an in vitro regulator of granulocyte and macrophage colony formation. We have determined that rGM-CSF also has intrinsic activity as a megakaryocyte colony-stimulating factor and that rGM-CSF augments the effect of int...

We investigated the effects of human rIL-4 on in vitro hematopoiesis. A profound inhibition of macrophage colony formation by IL-4 was observed, whereas colony growth of other lineages was not affected. Inhibition of macrophage colony growth was not restricted to GM-CSF-induced colony growth but was also present in cultures stimulated with M-CSF. This inhibition was not only observed in culture...

Previously we have shown that the zinc finger transcription factor Egr-1 is essential for and restricts differentiation of hematopoietic cells along the macrophage lineage, raising the possibility that Egr-1 actually plays a deterministic role in governing the development of hematopoietic precursor cells along the monocytic lineage. To test this hypothesis, we have taken advantage of interleuki...
