Prostaglandin regulation of colony-stimulating factor production by lipopolysaccharide-stimulated murine leukocytes.

ABSTRACT

The production of colony-stimulating factor by lipopolysaccharide-stimulated murine peritoneal leukocytes and their adherent subpopulations (greater than 80% macrophages) was markedly enhanced by indomethacin at concentrations sufficient to block prostaglandin E synthesis. Addition of physiological concentrations of E-series prostaglandins reversed this enhancing effect of indomethacin in a dose-dependent manner. These results indicate that colony-stimulating factor production by stimulated leukocytes is regulated by E-series prostaglandins and suggest that prostaglandins function to limit myelopoiesis by inhibiting colony-stimulating factor production and concomitantly the induction of cell proliferation.
