Synthetic ceramide analogues increase amyloid-β 42 production by modulating γ-secretase activity.

Abstract excerpt

γ-Secretase cleaves amyloid β-precursor protein (APP) to generate amyloid-β peptide (Aβ), which is a causative molecule of Alzheimer disease (AD). The C-terminal length of Aβ, which is determined by γ-secretase activity, determines the aggregation and deposition profiles of Aβ, thereby affecting the onset of AD. In this study, we found that the synthetic ceramide analogues...
