Mechanistic description
The debate supports carrying forward LRP1-mediated tau uptake disruption as an initiator of early tau propagation only if a proximal endpoint changes before the late outcome. The decisive validation path is: cell-type-specific LRP1 perturbation with live tau uptake, trans-synaptic spread, and vascular safety readouts.
Mechanism / pathway
- LRP1
- neurodegeneration
Evidence for (1)
Preregistered claim: LRP1-mediated tau uptake disruption in neurons initiates the earliest tau propagation cascade; blocking LRP1 prevents downstream spreading
Evidence against (1)
LRP1 has broad vascular and lipid roles, so blocking uptake may trade tau reduction for impaired clearance or vascular toxicity
