Mechanistic description

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.

Mechanism / pathway

  1. tight-junction remodeling
  2. tight-junction remodeling
  3. neurodegeneration
