1 Recently, we reported that human monocyte colony-stimulating factor (M-CSF) stimulates the clearance of lipoproteins containing apoB100 via both low density lipoprotein receptor-dependent and -independent pathways in target cells of M-CSF, and reduces plasma cholesterol level (Journal of Biological Chemistry, 265:12869-12875, 1990).

3 Furthermore, we found a significant role of M-CSF in cholesterol metabolism of human monocyte-derived macrophages. Cholesterol colony stimulating factor 1 Homo sapiens
4 M-CSF enhanced not only the uptake of acetylated low density lipoprotein and oxidized low density lipoprotein in macrophages, but also the efflux of cholesterol from cholesterol-loaded macrophages. Cholesterol colony stimulating factor 1 Homo sapiens
5 M-CSF enhanced not only the uptake of acetylated low density lipoprotein and oxidized low density lipoprotein in macrophages, but also the efflux of cholesterol from cholesterol-loaded macrophages. Cholesterol colony stimulating factor 1 Homo sapiens
6 To elucidate in vivo effects of M-CSF on cholesterol efflux from tissues, we administered an intravenous injection of 3H-cholesterol (150 microCi) into WHHL rabbits 1 month before starting M-CSF treatment. Cholesterol colony stimulating factor 1 Homo sapiens
7 We observed an increased cholesterol efflux from tissues to plasma high density lipoprotein after M-CSF treatment when cholesterol efflux was estimated as the change in specific radioactivity of plasma high density lipoprotein-cholesterol. Cholesterol colony stimulating factor 1 Homo sapiens
8 We observed an increased cholesterol efflux from tissues to plasma high density lipoprotein after M-CSF treatment when cholesterol efflux was estimated as the change in specific radioactivity of plasma high density lipoprotein-cholesterol. Cholesterol colony stimulating factor 1 Homo sapiens
9 This result suggests that M-CSF can enhance the excretion of cholesterol from target cells of M-CSF, such as cholesterol-loaded macrophages in the arterial wall, and reduce the rate of atherogenesis. Cholesterol colony stimulating factor 1 Homo sapiens
10 This result suggests that M-CSF can enhance the excretion of cholesterol from target cells of M-CSF, such as cholesterol-loaded macrophages in the arterial wall, and reduce the rate of atherogenesis. Cholesterol colony stimulating factor 1 Homo sapiens
11 This result suggests that M-CSF can enhance the excretion of cholesterol from target cells of M-CSF, such as cholesterol-loaded macrophages in the arterial wall, and reduce the rate of atherogenesis. Cholesterol colony stimulating factor 1 Homo sapiens
