Abstract

Increased evidence suggests that dysregulation of cholesterol metabolism may be a key event contributing to progression of multiple sclerosis (MS). Using an experimental autoimmune encephalomyelitis (EAE) model of MS we revealed specific changes in the mRNA and protein expression of key molecules involved in the maintaining of cholesterol homeostasis in the rat spinal cord: 3-hydroxy-3-methylglutaryl-coenzyme-A reductase (HMGCR), apolipoprotein E (ApoE) and cholesterol 24-hydroxylase (CYP46A1) during the course of disease. The presence of myelin lipid debris was seen only at the peak of EAE in demyelination loci being efficiently removed during the recovery period. Since CYP46A1 is responsible for removal of cholesterol excess, we performed a detailed profiling of CYP46A1 expression and revealed regional and temporal specificities in its distribution. Double immunofluorescence staining demonstrated CYP46A1 localization with neurons, infiltrated macrophages, microglia and astrocytes in the areas of demyelination, suggesting that these cells play a role in cholesterol turnover in EAE. We propose that alterations in the regulation of cholesterol metabolism at the onset and peak of EAE may add to the progression of disease, while during the recovery period may have beneficial effects contributing to the regeneration of myelin sheath and restoration of neuronal function.

  • Metabolic derangements of cholesterol lead to microglial activation, chronic inflammation, and progression of neurodegenerative diseases.

    “For example, metabolic derangements of cholesterol lead to microglial activation, chronic inflammation, and progression of NDs [65,66].”

    From Lipoprotein Lipase Regulates Microglial Lipid Droplet Accumulation (2021) · cites this paper as [66]

    The Introduction (page not specified) says cholesterol may promote inflammatory-mediator production by macrophages, creating a cycle of inflammation. The Abstract (page not specified) suggests altered cholesterol metabolism may contribute to progression of experimental autoimmune encephalomyelitis, a model of multiple sclerosis. Neither passage establishes that cholesterol derangements cause microglial activation and chronic inflammation or that this pathway drives neurodegenerative diseases generally. (LLM, conf=0.86)

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.
