LRP1 normally suppresses pro-atherogenic signaling in VSMCs through transcriptional regulation and autophagy control; its downregulation during atherosclerosis removes this inhibition, permitting P2RY12 upregulation and consequent foam cell accumulation. However, the mechanism lacks specificity (LRP1 regulates thousands of genes) and current druggability is poor—no small molecule restores LRP1 expression, and gene therapy cannot efficiently target medial VSMCs.
# LRP1-Dependent Tau Uptake Disruption in Tauopathic Neurodegeneration
## Background and Rationale
The progressive spreading of hyperphosphorylated tau pathology throughout the brain represents a hallmark of Alzheimer's disease and related tauopathies, including progressive supranuclear palsy, corticobasal degeneration, and frontotemporal lobar degeneration with tau inclusions. Central to this spreading mechanism is the intercellular transfer of pathological tau species, wherein diseased neuro
