Nathans explains that, normally, these blood vessel endothelial cells contain permeable "windows" and relatively loose "bolts" connecting the cells together. (sciencedaily.com)
Nathans adds, "We now know that endothelial cells that make up the blood-brain barrier have to receive signals constantly from nearby brain or retinal cells telling them, 'You're in the brain. (sciencedaily.com)
The "windows" in the other endothelial cells in the body are protein portals that allow large molecules to pass through easily -- to be filtered by the kidneys, for example. (sciencedaily.com)
So the body seals off these areas from bloodborne pathogens by tightening the "bolts" between and closing the "windows" of the endothelial cells that form the blood vessels servicing those areas. (sciencedaily.com)
