Preclinical effects of APOE ϵ4 on cerebrospinal fluid Aβ42 concentrations
Background: From earlier studies it is known that the APOE ϵ2/ϵ3/ϵ4 polymorphism modulates the concentrations of cerebrospinal fluid (CSF) beta-amyloid1-42 (Aβ42) in patients with cognitive decline due to Alzheimer's disease (AD), as well as in cognitively healthy controls. Here, in a large cohort consisting solely of cognitively healthy individuals, we aimed to evaluate how the effect of APOE on
