🧪 Overview

The same signal may be beneficial early and damaging late. Testing endothelial transcytosis with pericyte-protective dosing should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.

IF endothelial transcytosis defines the BBB therapeutic window, THEN inhibiting caveolae-mediated transcytosis early will reduce tracer leakage by >=30%, but late inhibition after gliosis will reduce leakage by <10%.
Predicted outcome: Early transcytosis inhibition reduces leakage >=30%; late inhibition reduces leakage <10% in the same model.
Falsification: Timing has no effect or late treatment rescues leakage as strongly as early treatment.

IF endothelial transcytosis is upstream of neurodegeneration biomarkers, THEN endothelial vesicle markers will increase >=20% before plasma NfL rises in longitudinal at-risk cohorts.
Predicted outcome: Endothelial transcytosis EV markers rise >=20% at a visit preceding NfL increase by at least 6 months.
Falsification: EV marker rise does not precede NfL or changes by <5%.
