Abstract

The role of microglia recruited from bone marrow (BM) into the CNS during the progression of Alzheimer's disease (AD) is poorly understood. To investigate whether beta-amyloid (Abeta) associated microglia are derived from blood monocytes, we transplanted BM cells from enhanced green fluorescent protein expressing mice into young or old transgenic AD mice and determined the engraftment of BM-derived cells into the brain and their relative distribution near Abeta deposits. When young transgenic mice were transplanted before the onset of AD-like pathology and the brains analyzed 6.5 months later, the number of engrafted cells was significantly higher than in age-matched wild type mice. Moreover, the number of BM-derived cells associated with Abeta was significantly higher than in old transgenic mice transplanted after the establishment of AD-like pathology. Local inflammation caused by intrahippocampal lipopolysaccharide injection significantly increased the engraftment of BM-derived cells in old AD mice and decreased the hippocampal Abeta burden. These results suggest that infiltration of BM-derived monocytic cells into the brain contributes to the development of microglial reaction in AD.

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.
