[Recent trends in research on lipoprotein metabolism]

New trends in the research works on lipoprotein metabolism are focused on four aspects, namely metabolism of remnant particles, VLDL's, LDL's and HDL's. Metabolic behaviors of remnants, VLDL's and HDL's are closely related to the concentration or percentage of small dense LDL particles which are more susceptible to oxidation. Hyperinsulinism and increased hepatic triglyceride lipase could be involved in these disorders.
