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.
The gap can be tested by treating tight-junction remodeling as an upstream driver rather than a passive correlate. If true, perturbing dynamic contrast MRI should shift CSF/serum albumin ratio before downstream neurodegeneration markers change.
