Cell-to-cell propagation of pathogenic tau is a major mechanism that contributes to spread of neurotoxic tau and neuronal death in Alzheimer’s disease. The low-density lipoprotein receptor-related protein 1 (LRP1) is the major receptor mediating uptake of tau into neurons and, thus, potentially contributing to pathogenic tau propagation throughout the brain. We have identified a viral glycoprotein that can bind LRP1 with high affinity and potently block tau engagement. In this project, we will structural and biochemical methods to characterize LRP1-tau interactions and investigate how the viral glycoprotein can block LRP1-mediated tau spreading. We also expect our studies to develop a framework to design new therapies to inhibit the propagation of pathogenic tau in AD and other dementias.
