24-Hydroxycholesterol is a substrate for hepatic cholesterol 7α-hydroxylase (CYP7A) [PDF]
(24S)-Hydroxycholesterol is formed from cholesterol in the brain and is important for cholesterol homeostasis in this organ. Elimination of (24S)-hydroxycholesterol has been suggested to occur in the liver but little is known about the metabolism of this

Plasma 24S-hydroxycholesterol (cerebrosterol) is increased in Alzheimer and vascular demented patients [PDF]
Alzheimer's disease (AD) is characterized by the presence of senile plaques, neurofibrillary tangles, and neuronal cell loss associated with membrane cholesterol release.

Liver X Receptor α (LXRα) Regulates 5β-Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism. [PDF]
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

Physiological Functions of Side-Chain-Retaining Sterols in the Brain and Their Roles in Neurodegenerative Diseases [PDF]
Although the brain comprises only 2% of total body weight, it contains approximately 23% of the total cholesterol of the body. In the brain, cholesterol plays a critical role as a structural component of cell membranes and myelin sheaths.

Adaptive responses induced by 24S-hydroxycholesterol through liver X receptor pathway reduce 7-ketocholesterol-caused neuronal cell death [PDF]
Lipid peroxidation products have been known to induce cellular adaptive responses and enhance tolerance against subsequent oxidative stress through up-regulation of antioxidant compounds and enzymes.

Assessment of brain cholesterol metabolism biomarker 24S-hydroxycholesterol in schizophrenia. [PDF]
AbstractPlasma 24S-hydroxycholesterol mostly originates in brain tissue and likely reflects the turnover of cholesterol in the central nervous system. As cholesterol is disproportionally enriched in many key brain structures, 24S-hydroxycholesterol is a promising biomarker for psychiatric and neurologic disorders that impact brain structure.

Linking oxysterols and different stages of mild cognitive impairment: insights from gut metabolites and N6-methyladenosine [PDF]
Background Oxysterols, gut metabolites, and N6-methyladenosine (m6A) are extensively implicated in the pathogenesis of cognitive dysfunction, while their alterations in different stages of mild cognitive impairment (MCI) have not been elucidated ...

Treatment with efavirenz extends survival in a Creutzfeldt-Jakob disease model by regulating brain cholesterol metabolism [PDF]
Prion diseases are fatal, infectious, and incurable neurodegenerative conditions affecting humans and animals, caused by the misfolding of the cellular prion protein (PrPC) into its pathogenic isoform, PrPSc. In humans, sporadic Creutzfeldt-Jakob disease
