The cholesterol 24-hydroxylase activates autophagy and decreases mutant huntingtin build-up in a neuroblastoma culture model of Huntington’s disease [PDF]

, 2020
Objective Compromised brain cholesterol turnover and altered regulation of brain cholesterol metabolism have been allied with some neurodegenerative diseases, including Huntington’s disease (HD).

Excitotoxicity increases the release of 24S-hydroxycholesterol via CYP46A1 activation [PDF]

Mol Neurodegener, 2013
Background Excitotoxicity, a common hallmark of different neurological disorders including Alzheimer’s disease (AD), is the consequence of exacerbated neuronal stimulation and leads to a high influx of calcium trough membrane glutamate receptors [1]. On the other hand, high levels of the cholesterol metabolite 24S-hydroxycholesterol (24-HC) have been ...

Ventriculoperitoneal Shunt Treatment Increases 7 Alpha Hy-Droxy-3-Oxo-4-Cholestenoic Acid and 24-Hydroxycholesterol Concentrations in Idiopathic Normal Pressure Hydrocephalus

Brain Sciences, 2022
Idiopathic normal pressure hydrocephalus (iNPH) is the most common form of hydrocephalus in the adult population, and is often treated with cerebrospinal fluid (CSF) drainage using a ventriculoperitoneal (VP) shunt.

Changes in the levels of cerebral and extracerebral sterols in the brain of patients with Alzheimer's disease

Journal of Lipid Research, 2004
24S-hydroxycholesterol is a side-chain oxidized oxysterol formed in the brain that is continuously crossing the blood-brain barrier to reach the circulation. There may be an opposite flux of 27-hydroxycholesterol, which is formed to a lower extent in the

Cholesterol homeostasis in human brain: turnover of 24S-hydroxycholesterol and evidence for a cerebral origin of most of this oxysterol in the circulation

Journal of Lipid Research, 1998
We have previously demonstrated that the brain contains about 80% of the 24S-hydroxycholesterol in the human body and that there is a net flux of this steroid from the brain into the circulation (Lütjohann, D. et al. 1996. Proc. Natl. Acad. Sci. USA. 93:

Oxysterols in the circulation of patients with the Smith-Lemli-Opitz syndrome: abnormal levels of 24S- and 27-hydroxycholesterol

Journal of Lipid Research, 2001
Infants with the cholesterol synthesis defect Smith-Lemli-Opitz syndrome (SLO) have reduced activity of the enzyme 7-dehydrocholesterol-7-reductase and accumulate 7-dehydrocholesterol, with the highest concentration in the brain.

24(S)-Hydroxycholesterol protects the ex vivo rat retina from injury by elevated hydrostatic pressure [PDF]

, 2016
In the central nervous system, 24(S)-hydroxycholesterol (24(S)-HC) is an oxysterol synthesized from cholesterol by cholesterol 24-hydroxylase (CYP46A1) encoded by the cyp46a1 gene.

Highly automated nano-LC/MS-based approach for thousand cell-scale quantification of side chain-hydroxylated oxysterols[S]

Journal of Lipid Research, 2014
Iso-octyl chain-hydroxylated oxysterols were determined in attomoles per 10,000 cells concentrations in 10,000–80,000 cultured pancreatic adenocarcinoma cells, using a sensitive, highly automated nano-LC-ESI-MS-based method.
