Aging-Related Alterations of Glymphatic Transport in Rat: In vivo Magnetic Resonance Imaging and Kinetic Study

Frontiers in Aging Neuroscience, 2022
ObjectiveImpaired glymphatic waste clearance function during brain aging leads to the accumulation of metabolic waste and neurotoxic proteins (e.g., amyloid-β, tau) which contribute to neurological disorders.

AQP1 and AQP4 Contribution to Cerebrospinal Fluid Homeostasis

Cells, 2019
Aquaporin 1 (AQP1), expressed in epithelial cells of the choroid plexus, and aquaporin 4 (AQP4) present in ependymal cells and glia limitants have been proposed to play a significant role in cerebrospinal fluid (CSF) production and homeostasis.

Morphometric changes in lateral ventricles of patients with recent-onset type 2 diabetes mellitus. [PDF]

PLoS ONE, 2013
It is becoming increasingly evident that type 2 diabetes mellitus can have effects on global and regional brain morphology. Ventricular enlargement reflecting cerebral atrophy has been reported particularly in elderly type 2 diabetes patients.
