Macrophage colony-stimulating factor (CSF-1) binds to a receptor (CSF-1R) encoded by the c-fms proto-oncogene and activates transcription of the urokinase plasminogen activator (uPA) gene in murine bone-marrow-derived macrophages. This article demonstrates that the murine macrophage cell line RAW264 responds to CSF-1 with inducible phosphorylation of cytoplasmic proteins on tyrosine residues bu...

Granulocyte colony-stimulating factor (G-CSF) regulates granulocyte precursor cell proliferation, neutrophil survival, and activation. Cyclic hematopoiesis, a disease that occurs both in humans and grey collie dogs is characterized by cyclical variations in blood neutrophils. Although the underlying molecular defect is not known, long-term daily administration of recombinant G-CSF eliminates th...

Interleukin (IL)-17 is a recently discovered cytokine, which is proposed to play a role in neutrophilic airway inflammation via the release of proinflammatory cytokines and chemokines. To evaluate the role of IL-17 in inflammatory protein production from the airway epithelium, we have analyzed the effects of IL-17 on primary human bronchial epithelial cells (HBECs). Using gene arrays, changes i...

BACKGROUND AND PURPOSE We examined the therapeutic effect of human extracellular superoxide dismutase (ECSOD) gene transfer in the prevention of delayed cerebral vasospasm after experimental subarachnoid hemorrhage (SAH) because it was reported ECSOD relieved early-stage vasospasm. METHODS Twenty mongrel dogs were divided randomly into 4 groups to serve as control, SAH, SAH+adenovirus ECSOD (...

AIMS To assess the safety and effects of combined treatment with vascular endothelial growth factor-A(165) plasmid (VEGF-A(165)) and granulocyte- colony stimulating factor (G-CSF) mobilization of bone marrow stem cells in patients with severe chronic ischaemic heart disease (IHD). METHODS AND RESULTS Sixteen patients with severe chronic IHD were treated with intramyocardial injections of VEGF...

Mouse myeloid stem cell line D35 was obtained from a primary cell culture of C3H bone marrow cells. This cell grows completely dependent on the multi-lineage colony-stimulating factor (multiCSF; IL-3) or the granulocyte macrophage colony-stimulating factor (GMCSF). By serial dilution of the medium every 3 days, autonomously growing mutants were obtained spontaneously at the rate of 108 -107 . A...

Abstract Background and Aims Focal segmental glomerulosclerosis (FSGS) is the most common glomerular cause leading to end-stage kidney disease. Actual treatment of primary FSGS by immunosuppressive agents presents inconsistent results. Thus, new innovative strategies different from those used date taking into consideration podocyte renewal maintenance or even complementary immunosuppression are...

Particle-mediated gene delivery was used to immunize mice against melanoma. Mice were immunized with a plasmid cDNA coding for the human melanoma-associated antigen, gp100. Murine B16 melanoma, stably transfected with human gp100 expression plasmid, was used as a tumor model. Particle-mediated delivery of gp100 plasmid into the skin of naïve mice resulted in significant protection from a subseq...

We used the promoter of the human C-reactive protein (CRP) gene to drive inflammation-inducible overexpression of the cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) in transgenic mice. Transgenic mice carrying a CRP/GM-CSF fusion gene show a >150-fold increases in circulating levels of GM-CSF within 6 h of intraperitoneal inoculation with 25 microg of lipopolysaccharide. How...

Granulocyte/macrophage colony-stimulating factor (GM-CSF) is a key cytokine in myelopoiesis and aberrant expression is associated with chronic inflammatory disease and myeloid leukemias. This aberrant expression is often associated with constitutive nuclear factor (NF)-kappaB activation. To investigate the relationship between NF-kappaB and GM-CSF transcription in a chromatin context, we analyz...
