Topic: Disease mechanisms in lab and animal studies

Plain-language summary

Although biotherapeutics have vast potential for treating brain disorders, their use has been limited due to low exposure across the blood-brain barrier (BBB). We report that by manipulating the binding mode of an antibody fragment to the transferrin receptor (TfR), we have developed a Brain Shuttle module, which can be engineered into a standard therapeutic antibody for successful BBB transcytosis. Brain Shuttle version of an anti-Aβ antibody, which uses a monovalent binding mode to the TfR, increases β-Amyloid target engagement in a mouse model of Alzheimer's disease by 55-fold compared to the parent antibody. We provide in vitro and in vivo evidence that the monovalent binding mode facilitates transcellular transport, whereas a bivalent binding mode leads to lysosome sorting. Enhanced target engagement of the Brain Shuttle module translates into a significant improvement in amyloid reduction. These findings have major implications for the development of biologics-based treatment of brain disorders.

Built from the record alzhub holds for this paper, not looked up. Volume, issue and page numbers are not held in the record. The record's author list ends in “et al.”, so not every author is named. Check the citation against the original before you use it.

How to read this study

Design: our record does not state a study design, so check the methods section of the original before weighing the result.
Size: the record gives no participant count. Look for one in the original before trusting a pattern.
Effect: the record gives no effect size, so the summary above cannot say how large any difference was.

What the evidence grade means here

This page is graded low. alzhub.org assigns the grade automatically from keywords in the abstract, not from reading the paper. Low means the abstract matched neither pattern. It is the default label, and it does not mean the work is poor; many sound lab and imaging papers land here. It can add at most 5 of the 100 points in the study score, and it is a label about design, not a verdict on whether the findings are true.

How this study scored 36/100

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / 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 and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
