Macrophage colony-stimulating factor in patients with rheumatoid arthritis.

Rheumatoid synovial endothelial cells produce macrophage colony-stimulating factor leading to osteoclastogenesis in rheumatoid arthritis.

OBJECTIVES Periarticular osteoporosis and joint destruction are major complications in rheumatoid arthritis (RA), caused by osteoclast-mediated bone resorption. However, the mechanisms of monocyte/osteoclast maturation and role of RA endothelial cells (RAECs) in the control of osteoclastogenesis remain unclear. The present study was designed to determine the most important factors that influenc...

Macrophage Colony-Stimulating Factor

Granulocyte-macrophage colony-stimulating factor in Staphylococcus aureus-induced arthritis.

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a cytokine that is able to increase not only the production of phagocytic cells but also their efficacy with respect to, e.g., bactericidal properties. In this study, we wanted to analyze the impact of GM-CSF on experimental Staphylococcus aureus-induced arthritis. For that purpose, mice were administered GM-CSF before and after bacte...

Granulocyte Macrophage Colony-Stimulating Factor

Experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis, can be induced by immunization with a number of myelin antigens. In particular, myelin oligodendrocyte glycoprotein, a central nervous system (CNS)-specific antigen expressed on the myelin surface, is able to induce a paralytic MS-like disease with extensive CNS inflammation and demyelination in several strains of ...

Granulocyte-Macrophage Colony-stimulating Factor

We show that 1,25-dihydroxyvitamin D3 (1,25[0H12D3), the most hormonally active metabolite of vitamin 113, modulates sensitively and specifically both the protein and messenger RNA accumulation of the multilineage growth factor granulocyte-macrophage colony-stimulating factor (GM-CSF). The regulation of GMCSF expression is seen in both normal human mitogen-activated T lymphocytes and T lymphocy...
