Cholesterol in brain disease: Sometimes determinant and frequently implicated

Open access

Abstract

Cholesterol is essential for neuronal physiology, both during development and in the adult life: as a major component of cell membranes and precursor of steroid hormones, it contributes to the regulation of ion permeability, cell shape, cell-cell interaction, and transmembrane signaling. Consistently, hereditary diseases with mutations in cholesterol-related genes result in impaired brain function during early life. In addition, defects in brain cholesterol metabolism may contribute to neurological syndromes, such as Alzheimer's disease (AD), Huntington's disease (HD), and Parkinson's disease (PD), and even to the cognitive deficits typical of the old age. In these cases, brain cholesterol defects may be secondary to disease-causing elements and contribute to the functional deficits by altering synaptic functions. In the first part of this review, we will describe hereditary and non-hereditary causes of cholesterol dyshomeostasis and the relationship to brain diseases. In the second part, we will focus on the mechanisms by which perturbation of cholesterol metabolism can affect synaptic function.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The beneficial effects of statins in Mecp2-deficient mice presumably reflect mechanisms of action other than inhibition of cholesterol synthesis, given that brain cholesterol synthesis is already moderately suppressed in these mice.

    “As statins were designed to act primarily by inhibiting cholesterol synthesis, their beneficial effects in the Mecp2-deficient mouse presumably reflect other mechanisms of action given that brain cholesterol synthesis is already moderately suppressed in these mice (Orth and Bellosta, 2012; Martin et al., 2014).”

    From Suppression of brain cholesterol synthesis in male Mecp2-deficient mice is age dependent and not accompanied by a concurrent change in the rate of fatty acid synthesis (2017) · cites this paper as Martin et al., 2014

    The ‘Cholesterol in brain disease: hereditary causes’ section (page unavailable) reports decreased brain sterol synthesis in adult Mecp2-mutant mice and improved behavior and lifespan after fluvastatin treatment. The ‘Therapeutic approaches to cholesterol-related brain diseases’ section (page unavailable) describes other possible beneficial actions of statins. The paper does not conclude that those other actions explain fluvastatin’s benefits in the Mecp2-deficient mice. (LLM, conf=0.86)

  • Diet-derived cholesterol cannot cross the BBB and cannot compensate the low cholesterol level in the brain of SLOS patients with neurologic symptoms.

    “Nevertheless, diet-derived cholesterol cannot cross the BBB and cannot compensate the low cholesterol level in the brain [3,24].”
  • The most severe DHCR7 mutations cause fetal or newborn death, while less severe variants cause developmental defects in specific organs such as facial and cranial malformations, hypospadia or complete gonadal absence.

    “The most severe mutations of this gene cause fetal or newborn death, while less severe variants cause developmental defects in specific organs such as facial and cranial malformations, hypospadia or complete gonadal absence [24].”
  • Cholesterol has been implied in the production and clearance of beta amyloid.

    “Cholesterol has been implied in the production and clearance of beta amyloid [24].”
  • Disruption of cholesterol homeostasis perturbs cell-autonomous and non-cell-autonomous functions, including inhibition of crucial signaling pathways and cellular crosstalk.

    “Disruption of cholesterol homeostasis has also been shown to perturb cell-autonomous and non-cell-autonomous functions, including inhibition of crucial signaling pathways and cellular crosstalk (Bjorkhem and Meaney, 2004; Martin et al., 2014).”

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.
