Oxysterol-binding protein ORP6 regulates lipid metabolism and brain Aβ production

Journal of Lipid Research
The mammalian brain is the most cholesterol-rich organ of the body, relying on in situ de novo cholesterol synthesis. Maintaining cholesterol homeostasis is crucial for normal brain function.

Effects of brain cholesterol homeostasis imbalance on Alzheimer's disease and its related molecular mechanisms

Chinese Journal of Contemporary Neurology and Neurosurgery, 2022
The pathogenesis of Alzheimer's disease (AD) mainly includes the decrease of neurons and synapses, the deposition of the extracellular β⁃ amyloid protein (Aβ), the formation of neuritic plaques (NPs) and neurofibrillary tangles (NFTs) caused by ...

Urinary cholesterol: its association with a macromolecular protein- lipid complex [PDF]

, 1984
The cholesterol-containing complexes in the urine of normal subjects and patients with diseases accompanied by hyperexcretion of urinary cholesterol were characterized. In normal subjects, the major portion of the recovered urinary cholesterol was eluted

Systemic Extracerebral Atherosclerotic Burden and Dementia Risk After Incident Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Stroke survivors are at increased risk of dementia, but clinically accessible markers of risk heterogeneity remain limited. Previous studies have largely examined atherosclerotic disease in individual vascular beds rather than the overall burden of systemic extracerebral atherosclerosis.

Chronic cholesterol administration to the brain supports complete and long-lasting cognitive and motor amelioration in Huntington’s disease

Pharmacological Research, 2023
Evidence that Huntington's disease (HD) is characterized by impaired cholesterol biosynthesis in the brain has led to strategies to increase its level in the brain of the rapidly progressing R6/2 mouse model, with a positive therapeutic outcome.

Fibronectin in human gallbladder bile: cholesterol pronucleating and/or mucin "link" protein? [PDF]

, 1994
Some biliary proteins (pronucleators) seem to be essential factors for cholesterol crystal formation and crystal growth in bile. A recent study suggests that fibronectin is such a pronucleator in bile.

Effects of ursodeoxycholic acid on synthesis of cholesterol and bile acids in healthy subjects [PDF]

, 2004
Background/Aims: Ursodeoxycholic acid ( UDCA) decreases biliary secretion of cholesterol and is therefore used for the dissolution of cholesterol gallstones.

Caregiver Perspectives on the Burden of Disease and Treatment in Uncontrolled Gout

Arthritis Care &Research, EarlyView.
Objective Uncontrolled gout (UG) refers to persistently elevated serum urate (SU) levels >6 mg/dL and ongoing gout symptoms despite use of urate‐lowering therapy (ULT). The objective of this study was to evaluate the burden associated with informal caregiving for individuals with UG.

Physiological Functions of Side-Chain-Retaining Sterols in the Brain and Their Roles in Neurodegenerative Diseases

Metabolites
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.
