Immune cells and their derived molecules have major impact on brain function. Mice deficient in adaptive immunity have impaired cognitive and social function compared to that of wild-type mice. Importantly, replenishment of the T cell compartment in immune deficient mice restored proper brain function. Despite the robust influence on brain function, T cells are not found within the brain parenchyma, a fact that only adds more mystery into these enigmatic interactions between T cells and the brain. Our results suggest that meningeal space, surrounding the brain, is the site where CNS-associated

The lymphatic vessels (LVs) contribute to tissue homeostasis and function by facilitating the clearance of excess fluid and macromolecules from the interstitial tissue of the brain. Various routes for the extracranial transport of LV drainage from the brain parenchyma to the deep cervical lymph nodes were described. The purpose of current research is to show the presence, distribution, and average diameter of LVs accompanying the two arteries supplying the human brain tissue: internal carotid (ICA) and vertebral (VA) arteries in humans. The ICA and VA tissue samples were obtained from 3 human
