    Description: 27-Hydroxycholesterol is a selective estrogen receptor modulator and an agonist of the liver X receptor, it may negatively modulate cognitive effects and cholesterol metabolism in the brain. 27-Hydroxycholesterol can enhance cell release of IL-8, IL-1β, and TNF-α and to upregulate matrix metalloproteinase-9 (MMP-9) via TLR4/NF-κB-dependent pathway; it also can reduce hepatic inflammation in hyperlipidemic mice.
    Targets: Liver X Receptor | HMG-CoA Reductase | LDL | TLR | TNF-α | NF-kB | MMP(e.g.TIMP) | IL Receptor | P450 (e.g. CYP17)

    27-Hydroxycholesterol contributes to disruptive effects on learning and memory by modulating cholesterol metabolism in the rat brain.[Pubmed: 25987203]
    Cholesterol metabolism is important for neuronal function in the central nervous system (CNS). The oxysterol 27-Hydroxycholesterol (27-OHC) is a cholesterol metabolite that crosses the blood-brain barrier (BBB) and may be a useful substitutive marker for neurodegenerative diseases. However, the effects of 27-Hydroxycholesterol on learning and memory and the underlying mechanisms are unclear.
    METHODS AND RESULTS:
    To determine this mechanism, we investigated learning and memory and cholesterol metabolism in rat brain following the injection of various doses of 27-Hydroxycholesterol into the caudal vein. We found that 27-Hydroxycholesterol increased cholesterol levels and upregulated the expression of liver X receptor-α (LXR-α) and adenosine triphosphate (ATP)-binding cassette transporter protein family member A1 (ABCA1). In addition, 27-Hydroxycholesterol decreased the expression of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CR) and low-density lipoprotein receptor (LDLR) in rat brain tissues.
    CONCLUSIONS:
    These findings suggest that 27-Hydroxycholesterol may negatively modulate cognitive effects and cholesterol metabolism in the brain.

    27-hydroxycholesterol mediates negative effects of dietary cholesterol on cognition in mice.[Pubmed: 25453744]
    In spite of the fact that cholesterol does not pass the blood-brain barrier, treatment of mice with dietary cholesterol causes significant effects on a number of genes in the brain and in addition a memory impairment.
    METHODS AND RESULTS:
    We have suggested that these effects are mediated by 27-hydroxycholesterol, which is able to pass the blood-brain barrier. To test this hypothesis we utilized Cyp27-/- mice lacking 27-hydroxycholesterol. The negative effect on memory observed after treatment of wildtype mice with dietary cholesterol was not observed in these mice. The cholesterol diet reduced the levels of the "memory protein" Arc (Activity Regulated Cytoskeleton associated protein) in the hippocampus of the wildtype mice but not in the hippocampus of the Cyp27-/- mice.
    CONCLUSIONS:
    The results are consistent with 27-hydroxycholesterol as the mediator of the negative effects of cholesterol on cognition.
