The granulocyte-macrophage colony-stimulating factor GM-CSF. The preformed complex required only the extracellular regions of GMRa and bc , as shown by the ability of (GM-CSF) receptor is expressed on normal and malignant hematopoietic cells as well as on cells from other organs soluble bc to associate with membrane-anchored GMRa or soluble GMRa. Kinetic experiments on eosinophils and in which ...
Alcohol abuse dramatically increases the risk of acute lung injury. In an experimental rat model of ethanol-mediated susceptibility to lung injury, recombinant granulocyte/macrophage colony-stimulating factor (GM-CSF) restored alveolar epithelial barrier function both in vitro and in vivo, even during acute endotoxemia. These findings suggested that the alveolar epithelium, which secretes GM-CS...
BACKGROUND G-CSF and GM-CSF have both been shown to decrease the time to hematopoietic recovery when administered after autologous BM or peripheral stem cell re-infusion. However, few studies have compared G-CSF and GM-CSF to determine which is the preferred myeloid growth factor. METHODS This study compares a prospectively accrued cohort of 22 patients receiving GM-CSF with a historical coho...
High levels of granulocyte/macrophage-colony stimulating factor (GM-CSF) autoantibodies are thought to cause pulmonary alveolar proteinosis (PAP), a rare syndrome characterized by myeloid dysfunction resulting in pulmonary surfactant accumulation and respiratory failure. Paradoxically, GM-CSF autoantibodies have been reported to occur rarely in healthy people and routinely in pharmaceutical int...
OBJECTIVE To study the effect of granulocyte macrophage-colony-stimulating factor (GM-CSF) on histamine metabolism in arteriosclerosis, the expression of histidine decarboxylase (HDC; histamine-producing enzyme), histamine receptors 1 and 2 (HH1R and HH2R), and GM-CSF was investigated in human and mouse arteriosclerotic carotid arteries. Furthermore, the molecular mechanisms of GM-CSF-induced H...
We reported previously that treatment with all-trans retinoic acid (ATRA) and granulocyte macrophage colony-stimulating factor (GMCSF) induces differentiation of human myeloblastic leukemia ML-1 cells to granulocytes, whereas treatment with ATRA alone induces practically no differentiation of these cells. To investigate the mechanism of the synergistic effect of these factors, we examined the e...
Background Lipopolysaccharide- (LPS-) induced tumour necrosis factor alpha (TNFα) secretion in critically ill patients can be considered as a measure of immune responsiveness. It can be enhanced by granulocyte-macrophage colony stimulating factor (GM-CSF). We investigated the effect of GM-CSF on ex vivo stimulated cytokine production using various preincubation regimens in healthy donors and pa...
Hematopoietic growth factor receptors are present on cells of normal nonhematopoietic tissues such as endothelium and placenta. We previously demonstrated functional human granulocyte-macrophage colony-stimulating factor (GM-CSF) receptors on small cell carcinoma of the lung cell lines, and others have reported that certain solid tumor cell lines respond to GM-CSF in clonogenic assays. In the c...
Granulocyte-macrophage colony-stimulating factor (GM-CSF) enhances protection against tumors and infections, but GM-CSF-deficient mice develop inflammatory disease. Here we show that GM-CSF is required for the expression of milk fat globule EGF 8 (MFG-E8) in antigen-presenting cells, and that MFG-E8-mediated uptake of apoptotic cells is a key determinant of GM-CSF-triggered tolerance and immuni...
The effects of recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) were compared to those of media conditioned by the continuous bladder carcinoma line, HTB9 (HTB9-CM), using three criteria. First, both GM-CSF and HTB9-CM stimulated blast colony formation in methylcellulose cultures, patient-to-patient variations were seen in the dose-response curves, and GM-CSF was effective,...
