Figure 1From: BACE1 is at the crossroad of a toxic vicious cycle involving cellular stress and β-amyloid production in Alzheimer’s diseaseOxidative stress mediates Aβ-induced BACE1 transcriptional activation. Aβ peptides trigger oxidative stress by inducing ROS generation and impairing the antioxidant system. Oxidative stress and inflammatory cytokines activates JNK, then its transcription factor AP-1 upregulates BACE1. As BACE1 produces Aβ peptides, a vicious cycle is established. Aβ, amyloid peptide; AP-1, activator protein-1; BACE1, β-secretase βAPP cleaving enzyme 1; JNK, c-Jun N-terminal kinases; ROS, reactive oxygen species.Back to article page
