"Overrturning decades of textbook teaching, researchers at the University of Virginia School of Medicine have discovered that the brain is directly connected to the immune system by vessels previously thought not to exist.
The finding could have significant implications for the study and treatment of neurological diseases ranging from autism to Alzheimer’s disease to multiple sclerosis."
"The unexpected presence of the lymphatic vessels raises a tremendous number of questions that now need answers, both about the workings of the brain and the diseases that plague it.
For example: 'In Alzheimer’s, there are accumulations of big protein chunks in the brain,' Kipnis said. 'We think they may be accumulating in the brain because they’re not being efficiently removed by these vessels.'”
