Abstract

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
