Direct interaction of proteoglycan macrophage colony-stimulating factor and basic fibroblast growth factor

Direct interaction of proteoglycan macrophage colony-stimulating factor and basic fibroblast growth factor.

The proteoglycan form of macrophage colony-stimulating factor (PG-M-CSF), but not M-CSF with a molecular weight of 85 kD (85-kD M-CSF), bound to immobilized basic fibroblast growth factor (bFGF), and, conversely, bFGF bound to immobilized PG-M-CSF, but not to the 85-kD M-CSF. PG-M-CSF has an additional amino acid sequence at its carboxyl terminus (part of a precursor sequence that is removed in...

Macrophage Colony-Stimulating Factor

Factors regulating macrophage production and growth: identity of colony- stimulating factor and macrophage growth factor

The activities of a colony-stimulating factor (CSF), which stimulates granulocyte-macrophage colony formation by mouse hemopoietic cells, and macrophage growth factor (MGF), which stimulates proliferation of activated peritoneal macrophages, have been demonstrated by various criteria to reside in the same molecular species. These criteria include occurrence in various sources and copurification...

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...
