24(S)-Hydroxycholesterol is the major brain metabolite formed from cholesterol in the brain and is important for brain cholesterol homeostasis in addition to being an an endogenous agonist of the nuclear liver X receptors (LXRs).
24(S)-Hydroxycholesterol is the major brain metabolite formed from cholesterol in the brain and is important for brain cholesterol homeostasis in addition to being an an endogenous agonist of the nuclear liver X receptors (LXRs). Impairment of brain cholesterol metabolism has been associated with several neurodegenerative diseases, including multiple sclerosis, Alzheimer′s, and Huntington diseases. The exact role role of 24(S)-Hydroxycholesterol is unclear, and it may have differing effects depending on concentration. Low concentrations can protect neuronal cells against oxidative stress, while high concentrations induce necroptosis-like neuronal cell death. 24(S)-Hydroxycholesterol has also been found to be a potent allosteric modulator of N-methyl-d-aspartate receptors, potentiating NMDAR-mediated EPSCs in rat hippocampal neurons with an EC50 of 1.2 μM.

The major cholesterol metabolite in brain, 24(S)-hydroxycholesterol (24S-HC), serves as a vehicle for cholesterol removal. Its effects on neuronal function, however, have only recently begun to be investigated. Here, we review that nascent work. Our own studies have demonstrated that

N-methyl-D-aspartate receptors (NMDARs) are glutamate-gated ion channels that are critical to the regulation of excitatory synaptic function in the CNS. NMDARs govern experience-dependent synaptic plasticity and have been implicated in the pathophysiology of various neuropsychiatric disorders including the cognitive deficits

The aim of this paper was to more completely study the mitochondrial CYP27A1 initiated acidic pathway of cholesterol metabolism. The mitochondrial CYP27A1 initiated pathway of cholesterol metabolism (acidic pathway) is known to synthesize two well-described vital regulators of cholesterol/lipid homeostasis
