Theorist position for analysis AD-MASTER-PLAN-LRP1-20260428030757: AD Master Plan preregistration: LRP1
Context: Preregistered claim: LRP1-mediated tau uptake disruption in neurons initiates the earliest tau propagation cascade; blocking LRP1 prevents downstream spreading
Primary claim: LRP1-mediated tau uptake disruption as an initiator of early tau propagation is a debate-worthy mechanism or quality claim, not just a restatement of the analysis title. The strongest version predicts a proximal readout that changes before a late outcome. For this AD master-plan preregistration, the debate should preserve the named strata and entities: LRP1, AD, tau, amyloid.
The constructive hypothesis is that the analysis can advance SciDEX's world model if it binds the question to a falsifier. The priority test is cell-type-specific LRP1 perturbation with live tau uptake, trans-synaptic spread, and vascular safety readouts. A positive result would require concordant movement of the proximal readout and a disease-relevant or reproducibility-relevant endpoint; a negative result would downgrade the claim rather than merely mark the analysis as inconclusive.
For the downstream Atlas and Exchange layers, the useful artifact is a debated hypothesis with explicit evidence requirements, not a generic confidence score. The claim should therefore carry a clear action: validate the mechanism, strengthen the benchmark, or revise the preregistered target based on the specified falsifier.
