Cellular uptake of lipoproteins through LRP is apo e dependent

Research output: Contribution to journalArticlepeer-review


We have investigated the role of the low density lipoprotein (LDL) receptor and the LDL receptor related protein (LRP) in the cellular uptake of apoE-enriched lipoproteins. Experiments performed in vitro and in cultured cells involved either 'ligand blotting' or the measurement of apoE dependent cholesterol estrification following uptake of beta-VLDL by normal or LDL receptor deficient human fibroblasts. Our data indicate that ligand binding to LRP in vitro and LRP-dependent beta-VLDL uptake by living cells is absolutely dependent upon the presence of exogenous apoE.
