he brain lacks traditional lymphatic vessels. Instead, interstitial fluid is
eliminated along the basement membranes of capillaries and basement
membranes surrounding smooth muscle cells of arteries, towards the surface
of the brain. These intramural periarterial drainage pathways become modified
with ageing, possession of apolipoprotein E4 genotype, hyperlipidemia, resulting
in the accumulation of aggregated proteins such as amyloid-beta (A) in the
walls of arteries as cerebral amyloid angiopathy. Soluble antigens are eliminated
from the brain along the intramural periarterial drainage pathways, towards the
cervical lymph nodes. Arteries in the grey matter of the brain possess a layer of
leptomeninges as advenitita, whereas arteries in the white matter have two such
layers, with a potential perivascular space that becomes dilated when drainage of
fluid is impaired in the greymatter. Themotive force for efficient clearance of fluids
is provided by the contractions of smooth muscle cells and therapeutic strategies
to facilitate the clearance of fluid and prevent neurodegenerative diseases may be
based on adrenergic and cholinergic interventions.
Biography
Roxana Carare is a medically qualified Clinical Neuroanatomist
who has graduated in General Medicine in Bucharest Romania
in 1996 and completed her PhD in Experimental Neuropathol-
ogy in the Faculty of Medicine, University of Southampton, UK.
She has a rich educational portfolio and leads research into the
lymphatic drainage pathways of the brain. She has published
