The blood-brain barrier consists of specialized cells that line blood vessels passing through the brain. These cells collectively permit only certain molecules to pass to and from the brain, maintaining the distinct biochemistry and cell populations of the central nervous system versus the rest of the body. Where the blood-brain barrier leaks, the result is inflammation and dysfunction in brain tissue as, a reaction to the presence of unexpected and unwanted molecules and cells. Unfortunately the blood-brain barrier declines and malfunctions with age, as is the case for all complex biological systems. This is likely an important contribution to the development of <a href="https://en.wikipedia.org/wiki/Neurodegener…
The Aged Blood-Brain Barrier is More Vulnerable to Disruption by Hypoxia
