Physiology of Cerebrospinal Fluid Secretion, Recirculation, and Resorption Brett M. Morrison, in Cerebrospinal Fluid in Clinical Practice, 2009 INTRODUCTION The brain actually has two discrete fluid compartments: the interstitial fluid (ISF) space that surrounds the neurons and glia, and the cerebrospinal...
In searching for the drainage route of the interstitial fluid (ISF) in the deep brain, we discovered a regionalized ISF drainage system as well as a new function of myelin in regulating the drainage. The traced ISF from the caudate nucleus drained to the ipsilateral cortex along myelin fiber ...
Interstitial fluid transports nutrients and removes waste between the organs and tissues in our body. In the brain, interstitial fluid is thought to be composed of circulating cerebrospinal fluid, cellular waste and blood plasma, and past research has shown a link between interstitial fluid flow and...
This review surveys evidence for the flow of brain interstitial fluid (ISF) via preferential pathways through the brain, and its relation to cerebrospinal fluid (CSF). Studies over >100 years have raised several controversial points, not all of them resolved. Recent studies have usefully combined ...
CSF from the subarachnoid space moves rapidly into the brain along paravascular routes surrounding penetrating cerebral arteries, exchanging with brain interstitial fluid (ISF) and facilitating the clearance of interstitial solutes, such as amyloid beta, in a pathway that we have termed the "glymphatic...
In the absence of a true lymphatic system in the brain parenchyma, alternative clearance pathways for excess fluid and waste products have been proposed. Suggested mechanisms for clearance implicate a role for brain interstitial and cerebrospinal fluids. However, the proposed direction of flow, the an...
Interstitial fluid (ISF) refers to the fluid between the parenchymal cells and along the perivascular spaces (PVS). ISF plays a crucial role in delivering nutrients and clearing waste products from the brain. This narrative review focuses on the use of MRI techniques to measure various ISF charac...
The interstitial fluid (ISF) drainage pathway has been hypothesized to underlie the clearance of solutes and metabolites from the brain. Previous work has implicated the perivascular spaces along arteries as the likely route for ISF clearance; however, it has never been demonstrated directly. The ...
Here, using a unique large pore-sized membrane microdialysis, we characterized soluble Aβ oligomers in brain interstitial fluid (ISF) of awake, freely moving APP/PS1 transgenic and control WT mice. We could detect high-molecular-weight (HMW) and low-molecular-weight (LMW) Aβ oligomers in ...
