24-Hydroxycholesterol plays a significant role in the regulation of cholesterol homeostasis in the brain. It is involved in the conversion of excess cholesterol into a form that can be transported out of the brain, facilitating its elimination. This process is crucial for maintaining healthy brain function and preventing the accumulation of cholesterol, which could lead to neurodegenerative diseases. Additionally, 24-Hydroxycholesterol is studied for its potential implications in understanding and treating conditions such as Alzheimer's disease, where cholesterol metabolism is often disrupted. Its role in modulating the liver X receptor (LXR) pathway also makes it a subject of interest in research focused on lipid metabolism and inflammation.
