Summary
We incubated β-very low density lipoprotein (β-VLDL) from cholesterol-fed rabbits with βA4 amyloid peptide (43mer). βA4 associated with the apolipoprotein E moiety of the βVLDL. The binding of βA4 to apolipoprotein E could not be dissociated with sodium dodecyl sulphate. Unlike native βVLDL, the βA4/βVLDL complexes bound to the low-density lipoprotein (LDL) receptor-related protein of normal and familial hypercholesterolemia fibroblasts in culture. The βA/βVLDL complexes were taken up into the cells, but escaped proteolytic degradation. The cellular uptake of βA4/βVLDL com plexes was independent from the LDL receptor pathway; it was inhibited by an excess of unlabelled, activated α 2-macroglobulin. βA4 competed with the binding and the uptake, but not the degradation, of 125I-labelled α 2-macroglobulin in fibroblasts. Considered together, the data suggest that the association of βA4 with apolipoprotein E-containing lipoproteins gives rise to complexes that are endocytosed through the LDL receptor-related protein but fails to undergo proteolytic degradation in the lysosomes. These findings may be relevant to the pathobiochemistry of Alzheimer’s disease.
