Abstract

Recent reports suggest a relationship between traumatic brain injury and the precocious development of neurodegenerative cascades, including diffuse deposits of beta-amyloid peptides (A beta) in the injured brain. Because the lateral fluid-percussion (FP) model of experimental brain injury produces clinically relevant neuropathological sequelae in the rat brain, we used this model together with a series of antibodies specific for amyloid precursor proteins (APPs), APP-like proteins (APLPs), or A beta to identify acute neurodegenerative changes after brain trauma. Male Sprague-Dawley rats were anesthetized and subjected to lateral FP brain injury of moderate to high severity. At 1 hr, 2 hr, 48 hr, 1 week, or 2 weeks after injury, animals were killed and their brains were removed for immunohistochemical analysis. APP/APLP immunoreactivity increased in specific brain regions as early as 1 hr after injury and persisted for at least 2 weeks. Axons in the thalamus and subcortical white matter showed the greatest APP/APLP accumulation. Injured cortex, striatum, cingulum, and hippocampus also demonstrated significant axonal accumulations of APP/APLP. Accumulation of APP/APLPs occurred primarily ipsilateral to the injury, although bilateral changes were observed in some brain regions. No deposition of A beta was observed in any brain region at any time point examined. These results demonstrate a pattern of widespread axonal pathology after lateral FP brain injury in the rat, characterized by intra-axonal accumulations of APP/APLP immunoreactivity in the absence of plaque- like deposits of A beta in the traumatized brain.

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.
