Cholesterol 0-11 beta-secretase 1 Homo sapiens 39-44 22551668-2 2012 We previously reported that cholesterol accumulation in NPC-cells leads to cholesterol-dependent increased APP processing by beta-secretase (BACE1) and decreased APP expression at the cell surface (Malnar et al. Cholesterol 28-39 beta-secretase 1 Homo sapiens 141-146 22551668-2 2012 We previously reported that cholesterol accumulation in NPC-cells leads to cholesterol-dependent increased APP processing by beta-secretase (BACE1) and decreased APP expression at the cell surface (Malnar et al. Cholesterol 75-86 beta-secretase 1 Homo sapiens 141-146 22551668-5 2012 We hypothesized that increased formation of APP-CTFs and Abeta in NPC disease is due to cholesterol-mediated altered endocytic trafficking of APP and/or BACE1. Cholesterol 88-99 beta-secretase 1 Homo sapiens 153-158 22551668-7 2012 Moreover, we observed that NPC cells show cholesterol dependent sequestration and colocalization of APP and BACE1 within enlarged early/recycling endosomes which can lead to increased beta-secretase processing of APP. Cholesterol 42-53 beta-secretase 1 Homo sapiens 108-113 22551668-9 2012 Our findings suggest that increased cholesterol levels, such as in NPC disease and sporadic AD, may be the upstream effector that drives amyloidogenic APP processing characteristic for Alzheimer"s disease by altering endocytic trafficking of APP and BACE1.
