Alzheimer's disease amyloid-beta peptide modulates apolipoprotein E isoform specific receptor binding

Topic: Disease mechanisms in lab and animal studies
The major protein component of the extracellular deposits in Alzheimer's disease (AD) is a 4 kDa peptide termed amyloid-beta (Abeta). This peptide is known to bind apolipoprotein E (apoE), a key mediator of lipoprotein transport, in an isoform specific manner. Whilst these isoform specific effects on apoE are well recognized, the functional significance of this interaction is poorly understood. Here, we investigated the influence of Abeta on apoE-mediated lipoprotein binding to cells using fluorescently tagged lipoprotein-like emulsions. Using this approach, we demonstrate that Abeta enhanced the normally poor binding of apoE2 lipoprotein-like particles to fibroblasts in culture, whilst markedly reducing the binding of apoE3 and apoE4. This suggests that the action of apoE isoforms on cellular lipoprotein or cholesterol metabolism is differentially modulated by Abeta. This also suggests that Abeta may also compromise apoE function in the Alzheimer disease affected brain.
Key findings
- This suggests that the action of apoE isoforms on cellular lipoprotein or cholesterol metabolism is differentially modulated by Abeta.
- This also suggests that Abeta may also compromise apoE function in the Alzheimer disease affected brain.

How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 21 of the 56 points we could judge it on, which is 38 out of 100.
