For over 50 years, biologists and clinicians have studied lipoprotein lipase (LPL) and learned about its structure, function, cellular production, physiology, and human genetics. LPL is the principal enzyme that removes triglyceride from the bloodstream. It also determines plasma levels of high-density lipoprotein. Surprisingly, within the past several years, a number of new and unexpected proteins have been discovered that regulate the actions of LPL. These include the very low-density lipoprotein receptor, angiopoetin-like protein 3, and apolipoprotein A-V. In addition, mouse genetic studies have confirmed tissue culture findings of nonenzymatic roles of LPL both in lipid metabolism and atherogenesis. These basic observations are now being related to new information on human genetic polymorphism in this gene that is likely to affect clinical evaluation of lipoprotein disorders and cardiac risk.
