The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs).Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain.hree cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs).

CREATE-ing tools that deliver genes past the blood-brain barrier. Your brain has a natural defense that protects it from infection and harm, itâs called the blood-brain barrier (BBB). The BBB is a selectively permeable layer of tightly packed cells that separates the blood in your circulatory system from your brain.
