Delineation of a novel hepatic route for the selective transfer of unesterified sterols from high-density lipoproteins to bile: studies using the perfused rat liver.


Cholesterol is principally excreted from the body in bile as unesterified cholesterol (UC). Using the unesterified plant sterol, sitostanol (SIT), as a nonexchangeable analog for UC, we have found that high-density lipoproteins (HDL), but not low-density lipoproteins, provide a vehicle for the direct delivery of cholesterol to bile. To determine the… (More)
