The role of lipoprotein lipase in metabolism of normolipidemic very low density lipoprotein by macrophages

Abstract

It was demonstrated by using lipoprotein lipase (LPL) inhibitor benzene boronic acid (BBA) that LPL played a major role in the accumulation of triglycerides (TG) in mouse peritoneal macrophages exposed to rabbit normal very low density lipoproteins (N-VLDL). There wwere less free fatty acids (FFA) and much more N-VLDL-TG left in the media containing BBA than in the controls. TG accumulation in the cells was greatly diminished or even prohibited by BBA. Thus, we obtained direct evidence that LPL played a more important role than the receptor did in the uptake of N-VLDL-TG by mouse macrophages. The mechanisms of LPL action were discussed.
