A section of the brain from a stroke model reveals that, in the area affected by the stroke (left), there is increased expression of molecules that weaken the blood brain barrier (white signal).

In the inset, the small blood vessels in the brain, i.e. the cerebral microvasculature, can be seen at a higher magnification stained in red and the molecules that weaken the blood brain barrier are labeled in white.
