These studies examined the proposition that the small particle size of HDL3 in the plasma of hypertriglyceridemic subjects is the consequence of the sequential actions of lipid transfer protein and hepatic lipase on HDL. Incubation of unmodified total HDL or HDL3 in the presence of hepatic lipase resulted in a depletion of phospholipid, but little change in the size of the particles. On the other hand, HDL3 that had first been depleted of cholesteryl ester and enriched with triglyceride and phospholipid, during prior incubation with Intralipid and a source of lipid transfer protein, were much more susceptible to the action of hepatic lipase. When these modified HDL3 were incubated with hepatic lipase there was a depletion of the triglyceride and phospholipid content and a conversion into much smaller particles the same size as those predominant in hypertriglyceridemic subjects. These very small particles were derived from a population of modified particles that were larger than the original HDL3 and were within the size range of HDL2. It is proposed, therefore, that in the plasma of hypertriglyceridemic subjects there exists a dynamic balance between the formation of enlarged triglyceride-rich HDL and a secondary conversion of these particles by hepatic lipase to form populations of very small HDL.
