BBB in vitro model | Type of experiment | Special conditions | Documentation of BBB permeability increase | Tight junction proteins alterations | Reference |
|
BBMEC monolayers | Hypoxic stress | Glial conditioned-media treatment | Permeability studies with [14]-sucrose | Claudin-1 shows a significant increase following hypoxic stress |
[21] |
|
BBMEC monolayers | Hypoxia/reoxygenation | none | TEER measurements and [14]-sucrose transfer across the barrier | Significant increase in expression of occludin, ZO-1, and ZO-2 |
[131] |
|
Rat GP8/3.9 cells | ROS generating environment by a mixture of xanthine oxidase and hypoxanthine | — | TEER FITC-dextran permeability across the barrier | Decrease of occludin and claudin-5 expression after exposure to oxidative environment |
[103] |
|
PBMEC | Hypoxia | Coculture with astrocytes/C6 glioma cells | TEER and passage of [3H]inulin | Decreased ZO-1 immunoreactivity at regions of cell-cell contact | [43] |
|
BMVECs on a 8.0 m matrigel-based insert | MMPs aggression | Coculture with leukemic cells | 40 kDa dextran-FITC flux by flow cytometry analysis | Downregulation of ZO-1, claudin-5, and occludin | [132] |
|
hCMEC/D3 (immortalized human BEC line) | A peptides treatments | — | permeability to the paracellular tracer 70 kD FITC-dextran | Decrease in the occludin level, whereas claudin-5 and ZO-1 were unaffected | [85] |
|
Human BMVEC | Exposure to ROS | — | TEER and monocytes migration studies | Decreased occludin and ZO-1 total content, whereas claudin-5 expression depended on the type of stressor used | [91] |
