The brain is the most cholesterol rich organ in the body containing about 25% of the body’s free cholesterol. Cholesterol cannot pass the blood brain barrier and be imported or exported directly, instead it is synthesised in situ and metabolised to oxysterols, oxidised forms of cholesterol, which can pass the blood brain barrier. 24S-Hydroxycholesterol is the dominant oxysterol in brain after parturition but during development a myriad of other oxysterols are produced which persist as minor oxysterols after birth. During both development and in later life, oxysterols and other sterols interact with a variety of different receptors, including nuclear receptors e.g. liver X receptors; membrane bound G protein-coupled receptors e.g. smoothened; the endoplasmic reticulum resident proteins e.g. INSIG (insulin induced gene), or the cholesterol sensing protein SCAP (SREBP cleavage activating protein); and the ligand-gated ion channel N-methyl-D-aspartate receptors found in nerve cells. In this review we summaries the different oxysterols (neuro-oxysterol) and sterols (neuro-sterols) found in the central nervous system whose biological activity is transmitted via these different classes of protein receptors.
