Differences between meningeal lymphatic system and glymphatic system.

Parameter	Meningeal Lymphatic System	Glymphatic System
localization	dura mater	brain interstitium
structure	resemble lymphatic vessels from other organs, however, have also some characteristic features	perivascular astrocyte endfeet wall and brain interstitium
forces of fluid movement	probably contractile activity of collecting mLVs wall (similarly as in lymphatic vessels in other organs)	dependent on arterial pressure, respiratory, sleep and position of head
function	drainage of CSF from subarachnoid space, including venous sinuses to the deep cervical lymph nodes	CSF-ISF exchange in the brain parenchyma

Abbreviations: CSF - cerebrospinal fluid; ISF - interstitial fluid; mLVs - meningeal lymphatic vessels.
