LDLR, VLDLR and APOBR in the pathophysiology of sporadic Alzheimer’s disease

Alzheimer’s disease (AD) and cholesterol homeostasis have long been linked, most notably by the identification of apolipoprotein E‐ε4 allele as the strongest risk factor. Yet the mechanism by which its pathogenic isoform ε4 impacts AD has remained elusive. Different GWA studies have identified other potential risk factors, many of which are also involved in the maintenance, homeostasis, mobilisation, and distribution of cholesterol. The aim of this study was to analyse three candidate genes involved in cholesterol metabolism, which showed preliminary significance and are strongly related to cholesterol processes and APOE neurobiology.
