The participation of hepatic lipase in the initial uptake and processing of chylomicron remnants was studied in the isolated, perfused rat liver. Hepatic lipase activity was either reduced by preperfusion of livers with heparin or inhibited with specific rat hepatic lipase antibodies. [3H]palmitate-labeled chylomicron remnants were recirculated through control and treated livers for 15 min; the livers were then flushed, homogenized, and endosome-rich fractions were isolated. Depletion of hepatic lipase activity by both methods reduced the uptake of chylomicron remnants and hydrolysis of their component triglycerides by perfused rat livers, but at the same time significantly increased the rate of endocytosis of those chylomicron remnants taken up. We conclude that hepatic lipase facilitates, but is not essential for, the initial uptake of chylomicron remnants by rat liver. Furthermore, endocytosis of chylomicron remnants does not require binding to hepatic lipase or the associated hydrolysis of remnant lipids.
