Abstract

A number of hypotheses regarding how anti‐Aβ antibodies alter amyloid deposition have been postulated, yet there is no consensus as to how Aβ immunotherapy works. We have examined the in vivo binding properties, pharmacokinetics, brain penetrance, and alterations in Aβ levels after a single peripheral dose of anti‐Aβ antibodies to both wild‐type (WT) and young non‐Aβ depositing APP and BRI‐Aβ42 mice. The rapid rise in plasma Aβ observed after antibody (Ab) administration is attributable to prolongation of the half‐life of Aβ bound to the Ab. Only a miniscule fraction of Ab enters the brain, and despite dramatic increases in plasma Aβ, we find no evidence that total brain Aβ levels are significantly altered. Surprisingly, cerebral spinal fluid Aβ levels transiently rise, and when Ab:Aβ complex is directly injected into the lateral ventricles of mice, it is rapidly cleared from the brain into the plasma where it remains stable. When viewed in context of daily turnover of Aβ, these data provide a framework to evaluate proposed mechanisms of Aβ attenuation mediated by peripheral administration of an anti‐Aβ monoclonal antibody (mAb) effective in passive immunization paradigm. Such quantitative data suggest that the mAbs are either indirectly enhancing clearance of Aβ or targeting a low abundance aggregation intermediate.—Levites, Y., Smithson, L. A., Price, R. W., Dakin.

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.
