This stunning new research shows that the brain and central nervous system is no different from the rest of the body. We now can study how the immune system works in the brain, and how these lymphatic vessels allow or inhibit immune cells in brain tissue.
What do these newly discovered lymphatic cleansing and immunological systems share?
They are lymphatic vessels and rely on veins.
That's right. The glymphatic system which cleases our brain utilizes paravenous spaces, and the newly discovered immune system in the CNS drains along the dural sinuses.
The implication of these discoveries is monumental. If lymphatic vessels do not have adequate drainage, due to a stenotic dural sinus, jugular stenosis, mechanical impingement or venous problems, the brain's immune system and cleansing system will not function properly.
The venous system which drains the brain is essential for perfusion, cleansing and proper immune function.
