1 Incubation of the macrophages with heparin caused a marked increase in the secretion of lipoprotein lipase. Heparin lipoprotein lipase Mus musculus
2 Short incubations with heparin (5 min) caused a release of the enzyme into the media, while longer incubations caused a 2-8-fold increase in net lipoprotein lipase secretion which was maximal after 2-16 h depending on cell type, and persisted for 24 h. The effect of heparin was dose-dependent and specific (it was not duplicated by other glycosaminoglycans). Heparin lipoprotein lipase Mus musculus
3 The heparin-induced increase in lipoprotein lipase secretion was dependent on protein synthesis. Heparin lipoprotein lipase Mus musculus
4 The secretion of lipoprotein lipase by macrophages in response to low levels of heparin may be a significant factor in the formation of atherosclerotic lesions. Heparin lipoprotein lipase Mus musculus
