A nonmicellar, bile salt-independent mode of cholesterol transport in human bile involving phospholipid vesicles was recently reported by our group. In the present study, we have investigated the relative contribution of the phospholipid vesicles and mixed bile salt-phospholipid micelles to cholesterol transport in human hepatic and gallbladder biles. The vesicles (ca 800 A diameter) were demonstrated by quasi-elastic light scattering (QELS) in fresh bile and after chromatography. Gel filtration under conditions that preserved micellar integrity demonstrated that biliary cholesterol was associated with both vesicles and micelles. At low bile salt concentration, the vesicular phase was predominant and most of the cholesterol was transported by it. With increasing bile salt concentrations, a progressive solubilization of the vesicles occurred with a concomitant increase in the amount of cholesterol transported by micelles. The vesicular carrier may be of particular biological significance for cholesterol solubilization in supersaturated biles.
