Abstract

alpha-Synuclein and ubiquitin are two Lewy body protein components that may play antagonistic roles in the pathogenesis of Lewy bodies. We examined the relationship between alpha-synuclein, ubiquitin, and lipids in Lewy bodies of fixed brain sections or isolated from cortical tissues of dementia with Lewy bodies. Lewy bodies exhibited a range of labeling patterns for alpha-synuclein and ubiquitin, from a homogeneous pattern in which alpha-synuclein and ubiquitin were evenly distributed and overlapped across the inclusion body to a concentric pattern in which alpha-synuclein and ubiquitin were partially segregated, with alpha-synuclein labeling concentrated in the peripheral domain and ubiquitin in the central domain of the Lewy body. Lipids represented a significant component in both homogeneous and concentric Lewy bodies. These results suggest that Lewy bodies are heterogeneous in their subregional composition. The segregation of alpha-synuclein to Lewy body peripheral domain is consistent with the hypothesis that alpha-synuclein is continually deposited onto Lewy bodies.

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.
