Cholesterol homeostasis in human brain: evidence for an age-dependent flux of 24S-hydroxycholesterol from the brain into the circulation.
We have investigated whether side chain-hydroxylated cholesterol species are important for elimination of cholesterol from the brain. Plasma concentrations of 24-hydroxycholesterol (24-OH-Chol) inExpand
Cholesterol homeostasis in human brain: turnover of 24S-hydroxycholesterol and evidence for a cerebral origin of most of this oxysterol in the circulation.
TLDR
It is concluded that conversion into 24S-hydroxycholesterol is a quantitatively important mechanism for elimination of cholesterol from human brain and suggests that the liver is the major eliminating organ. Expand
Simvastatin strongly reduces levels of Alzheimer's disease β-amyloid peptides Aβ42 and Aβ40 in vitro and in vivo
TLDR
It is demonstrated that the widely used cholesterol-lowering drugs simvastatin and lovastatin reduce intracellular and extracellular levels of Aβ42 and Aβ40 peptides in primary cultures of hippocampal neurons and mixed cortical neurons, suggesting that lipids are playing an important role in the development of Alzheimer's disease. Expand
Dietary cholesterol, rather than liver steatosis, leads to hepatic inflammation in hyperlipidemic mouse models of nonalcoholic steatohepatitis
TLDR
Findings indicate that dietary cholesterol, possibly in the form of modified plasma lipoproteins, is an important risk factor for the progression to hepatic inflammation in diet‐induced NASH. Expand
High‐dose statins and skeletal muscle metabolism in humans: A randomized, controlled trial
TLDR
This study was designed to assess the effect of high‐dose statin treatment on cholesterol and ubiquinone metabolism and mitochondrial function in human skeletal muscle. Expand
Treatment with simvastatin in normocholesterolemic patients with Alzheimer's disease: A 26‐week randomized, placebo‐controlled, double‐blind trial
TLDR
In post hoc analysis, simvastatin significantly decreased Aβ40 levels in the cerebrospinal fluid of patients with mild Alzheimer's disease, and this change was not observed in more severely affected patients. Expand
24S-hydroxycholesterol in cerebrospinal fluid is elevated in early stages of dementia.
TLDR
The observed influence of the apolipoprotein E epsilon4 (APOE4) allele on CSF 24S-hydroxycholesterol concentrations with a gene-dosage effect suggests the existence of a link between the AD risk factor APOE4 and CNS cholesterol metabolism. Expand
Inhibition of Intestinal Cholesterol Absorption by Ezetimibe in Humans
TLDR
In humans, ezetimibe inhibits cholesterol absorption and promotes a compensatory increase of cholesterol synthesis, followed by clinically relevant reductions in LDL and total cholesterol concentrations. Expand
Plant sterols and plant stanols in the management of dyslipidaemia and prevention of cardiovascular disease.
TLDR
Functional foods with plant sterols/stanols may be considered in individuals with high cholesterol levels at intermediate or low global cardiovascular risk who do not qualify for pharmacotherapy and as an adjunct to pharmacologic therapy in high and very high risk patients who fail to achieve LDL-C targets on statins or are statin- intolerant. Expand
ATP‐binding cassette transporters G1 and G4 mediate cholesterol and desmosterol efflux to HDL and regulate sterol accumulation in the brain
TLDR
These findings provide the first in vivo demonstration of a role for Abcg4 in sterol efflux in the brain and show that Abcgl and AbcG4 have overlapping functions in astrocytes, promoting efflux of cholesterol, desmosterol, and possibly other sterol biosynthetic intermediates to HDL. Expand
