oxLDL/LOX-1/ROS Signaling Induces P2RY12 via Nrf2 Activation

oxLDL/LOX-1/ROS Signaling Induces P2RY12 via Nrf2 Activation starts from the claim that modulating OLR1 (LOX-1), NFE2L2 (Nrf2) within the disease context of neurodegeneration can redirect a disease-relevant process.

Mechanistic Overview


oxLDL/LOX-1/ROS Signaling Induces P2RY12 via Nrf2 Activation starts from the claim that modulating OLR1 (LOX-1), NFE2L2 (Nrf2) within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview oxLDL/LOX-1/ROS Signaling Induces P2RY12 via Nrf2 Activation starts from the claim that modulating OLR1 (LOX-1), NFE2L2 (Nrf2) within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview oxLDL/LOX-1/ROS Signaling Induces P2RY12 via Nrf2 Activation starts from the claim that Oxidized LDL accumulating in atherosclerotic lesions engages LOX-1 on VSMCs, generating ROS that activate Nrf2-mediated transcription of P2RY12. This creates a reinforcing loop where P2RY12-promoted foam cell formation increases oxLDL uptake, further amplifying P2RY12 expression. However, the Nrf2 paradox (atheroprotective Nrf2 driving pro-atherogenic P2RY12) and prior clinical failures of LOX-1 and Nrf2-targeted therapies substantially weaken translational potential.
