MeSH definition : A vascular waste clearance system in the brain analogous to the lymphatic system that
facilitates transporting of solutes and waste products from CEREBROSPINAL FLUID (CSF)
and brain INTERSTITIAL FLUID (ISF). CSF from the SUBARACHNOID SPACE enters the brain
periarterial spaces, into the interstitium via channels (e.g., AQUAPORIN 4 PROTEIN)
on astrocytic endfeet and exchanges with brain ISF before perivenous drainage of solutes
and waste.;
