| pubmed-article:208632 | pubmed:abstractText | The relative contribution of the parenchymal and nonparenchymal rat liver cells to the hepatic uptake of human and rat high density lipoprotein (HDL) and low density lipoprotein (LDL) was determined in vivo. Nonparenchymal cells, isolated 6 h after intravenous injection of iodinated human HDL and LDL, contained respectively 4.2 and 6.3 times the amount of trichloroacetic acid-precipitable radioactivity per mg cell protein as compared to parenchymal cells. For rat iodinated HDL and LDL these factors were 3.4 and 4.1, respectively. These results indicate that nonparenchymal liver cells play a substantial role in the hepatic uptake of human and rat HDL and LDL in vivo. | lld:pubmed |
