Brain cholesterol homeostasis in Wilson disease

Wilson disease (WD) is an autosomal recessive inherited disorder of copper (Cu) metabolism, resulting in pathological accumulation of Cu in many organs and tissues, predominantly in the liver and brain. There clearly is a close and complex relationship between Cu and the cholesterol's metabolic pathway; therefore any theory about the cholesterol metabolism in the brain of patients with WD must take it into account. The hypothesis presented in this paper is that the imbalance in cerebral copper homeostasis caused by WD may plays a key role in the derangement of the cholesterol homeostasis in the brain, and thus promoting the observed WD related neurological disorders.
