The crash of that communication system can impact diseases including Alzheimer's disease, stroke and multiple sclerosis. In the Lancet Neurology article, Banks and his colleagues called for more research to better understand how the blood-brain barrier relates to immune cells.

Because it passes no judgment on which foreign substances are there to treat diseases and which are penetrating the brain to do harm, it locks all of them out. That makes getting drugs into the brain where they can do their work in treating brain diseases difficult.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2007/12/071218101237.htm"><P>The blood-brain barrier is woefully misunderstood, said Banks, who also is a staff physician at Veterans Affairs Medical Center in St. Louis. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2007/12/071218101237.htm"><P>"The general theme of our review article is the blood-brain barrier is not a brick wall but a regulating interface between the brain and the rest of the body.
