title: Influence of lipid concentrations and age on transfer of plasma lipoprotein into human arterial intima.
abstract: Transfer of low-density lipoprotein (L.D.L.2) from plasma to arterial intima was studied in 16 patients undergoing arterial surgery. Autologous labelled lipoprotein was used to demonstrate that L.D.L.2 enters the intima from plasma. Net flux of L.D.L.2 appeared to increase with age. Within each age-group the net flux of L.D.L.2 showed a pronounced positive correlation with plasma-L.D.L.-cholesterol concentrations. This may account in part for the association between hypercholesterolaemia and the development of atherosclerosis.
