Interleukin-l (IL-l) treatment of human WI-38 lung fibroblasts results in granulocyte-macrophage colony-stimulating factor (GM-CSF) expression as well as a delayed increase in prostaglandin E2 (PGE,) production that closely correlates with the decline of GM-CSF mRNA levels. Pretreatment with PGE, reduces the IL-l induced GM-CSF mRNA and protein expression to 10% to 15% of control values at conc...
Granulocyte-macrophage colony stimulating factor (GM-CSF) stimulates the in vitro proliferation and differentiation of granulocytic and macrophage cells. This regulator is now known to act at other levels of hemopoietic regulation. The heterogeneity of GM-CSFs is not only related to the tissue of origin and the in vitro production method, but also to functional subclasses of the molecule that h...
To examine the biologic properties of the molecule encoded by the human gene for granulocyte-macrophage colony-stimulating factor (GM-CSF), we expressed the cloned complementary DNA (cDNA) in transfected monkey COS cells and purified the resultant protein. Purified biosynthetic human GM-CSF was added to cultures of normal hematopoietic progenitor cells in semisolid media, and the resulting colo...
Granulocyte-macrophage colony-stimulating factor (GM-CSF/CSF2) is a cytokine produced in the hematologic compartment that may enhance antitumor immune responses, mainly by activation of dendritic cells. Here, we show that more than one-third of human colorectal tumors exhibit aberrant DNA demethylation of the GM-CSF promoter and overexpress the cytokine. Mouse engraftment experiments with autol...
Interleukin-1 (IL-1) treatment of human WI-38 lung fibroblasts results in granulocyte-macrophage colony-stimulating factor (GM-CSF) expression as well as a delayed increase in prostaglandin E2 (PGE2) production that closely correlates with the decline of GM-CSF mRNA levels. Pretreatment with PGE2 reduces the IL-1 induced GM-CSF mRNA and protein expression to 10% to 15% of control values at conc...
Reed, Jacquelyn A., Machiko Ikegami, Eli R. Cianciolo, Wei Lu, Patricia S. Cho, William Hull, Alan H. Jobe, and JeffreyA. Whitsett. Aerosolized GM-CSF ameliorates pulmonary alveolar proteinosis in GM-CSF-deficient mice. Am. J. Physiol. 276 (Lung Cell. Mol. Physiol. 20): L556–L563, 1999.—Surfactant proteins and phospholipids accumulate in the alveolar spaces and lung tissues of mice deficient in...
Interleukin-3 (IL-3) and granulocyte/macrophage-colony-stimulating factor (GM-CSF) are responsible for maintaining survival and stimulating growth of early dormant hematopoietic progenitor cells (HPC). These cytokines exhibit extensive overlap, with GM-CSF supporting growth and differentiation of myeloid HPC. A characteristic shared by a diverse group of leukemogens is the ability to act synerg...
Accuracy in in vivo quantitation of brain function with positron emission tomography (PET) has often been limited by partial volume effects. This limitation becomes prominent in studies of aging and degenerative brain diseases where partial volume effects vary with different degrees of atrophy. The present study describes how the actual gray matter (GM) tracer concentration can be estimated usi...
Human immunodeficiency virus type 1 (HIV-1) infects cells of the monocyte/macrophage lineage. While infection of macrophages by HIV-1 is generally not cytopathic, it does impair macrophage function. In this study, we examined the effect of HIV-1 infection on intracellular signaling in human monocyte-derived macrophages (MDM) stimulated with the growth factor granulocyte-macrophage colony-stimul...
Pharmaceutical preparations of normal human immunoglobulin (IgG) are known to contain high-avidity and neutralizing antibodies (Ab) to the cytokines interleukin (IL)-1alpha, IL-6, and interferon (IFN)alpha. To test for other cytokine Ab, 23 batches of IgG were tested for saturable binding to eight 125I-labeled recombinant cytokines. All batches bound granulocyte-macrophage colony-stimulating fa...
