Transport of brain-derived neurotrophic factor across the blood–brain barrier

Abstract

Brain-derived neurotrophic factor (BDNF) is a potential therapeutic agent for degenerative disorders of the central nervous system. In this report, we investigated the ability of BDNF to cross the blood-brain barrier (BBB). BDNF was stable in blood up to 60 min after i.v. injection, with evidence for aggregation, and had an early, rapid influx into brain. By 10 min, most of the BDNF sequestered by the cerebral cortex was associated with the parenchyma rather than with the endothelial cells, demonstrating complete passage across the BBB. A small dose of unlabeled BDNF enhanced the entry of 125I-BDNF from blood to brain after an i.v. bolus injection, whereas larger doses had no effect. In contrast, a large dose of unlabeled BDNF inhibited the influx of 125I-BDNF during in situ brain perfusion. After intracerebroventricular injection, the efflux of BDNF from brain to blood occurred at a rate similar to that for reabsorption of cerebrospinal fluid, and no evidence for self-inhibition was found. Therefore, we conclude that intact BDNF in the peripheral circulation crosses the BBB by a high-capacity, saturable transport system.

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.
