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.

摘要

脂多糖刺激的小鼠腹腔白细胞及其贴壁亚群(超过80%为巨噬细胞)产生集落刺激因子的能力,在足以阻断前列腺素E合成的吲哚美辛浓度下显著增强。添加生理浓度的E系列前列腺素可剂量依赖性地逆转吲哚美辛的这种增强作用。这些结果表明,受刺激白细胞产生集落刺激因子受E系列前列腺素调控,并提示前列腺素通过抑制集落刺激因子产生以及随之而来的细胞增殖诱导,发挥限制骨髓生成的作用。
