Peri-capillary VRS water dynamics. Brain capillary endothelial tight junctions and active suppression of AQP-1 expression highly restricts water movement across the BBB. By contrast, significant water flow (blue arrow) is present inside the BBB within VRS (interstitial flow), mediated by active water inflow through AQP-4. Modified from Reference [9].
