Scientists discover new structures in the body and brain.

Lymphatic vessels function as the pathway for immune cells to move through the body to fight infection and disease. Researchers were certain that these vessels did not exist in the brain. Now they know that they do — and this has potentially profound significance.

“The immune link with so many neurological disorders is now obvious,” Kipnis says. “If the immune system is involved with those disorders, [then] the communication between the brain and the immune system is mediated by these vessels. We believe that they probably will be found to play a major role in most, if not all, neurological conditions where the immune system is involved.”

This research will have a huge impact on the continued research on all learning difficulties.
