Abstract

24-hydroxycholesterol (24OH-C) is synthesized almost exclusively in neurons. This oxysterol is mostly present as ester form in both cerebrospinal fluid and plasma. The enzyme lecithin-cholesterol acyltransferase esterifies 24OH-C in the brain, and the level of 24OH-C esters in cerebrospinal fluid was found to be correlated with the level of 24OH-C esters in plasma. Decreased levels of 24OH-C esters levels were previously found in Alzheimer's disease and Amyotrophic Lateral Sclerosis. This finding was attributed to the inhibitory effect of oxidative stress on lecithin-cholesterol acyltransferase activity in neurodegenerative conditions. Data reported here show that the plasma level of 24OH-C esters is decreased also in Parkinson's disease. ROC analysis identified 69.0% of 24OH-C esterification as the threshold (AUC = 0.98) discriminating patients (N = 19) from healthy subjects (N = 19) with 100% specificity vs controls, 89.5% sensitivity, 94.7% accuracy, and 100% precision. The level of 24OH-C esters was not correlated with UPDRS I or UPDRS III when evaluated at the time of blood sampling. By contrast, it was negatively correlated with UPDRS I (r = -0.4984, p = 0.0299) after one year of follow up. Therefore, this level might rep...Continue Reading
