Journal ArticleDOI
A paravascular pathway facilitates CSF flow through the brain parenchyma and the clearance of interstitial solutes, including amyloid β.
Jeffrey J. Iliff,Minghuan Wang,Minghuan Wang,Yonghong Liao,Benjamin A. Plogg,Weiguo Peng,Georg Andreas Gundersen,Helene Benveniste,G. Edward Vates,Rashid Deane,Steven A. Goldman,Erlend A. Nagelhus +11 more
TL;DR: An anatomically distinct clearing system in the brain that serves a lymphatic-like function is described and may have relevance for understanding or treating neurodegenerative diseases that involve the mis-accumulation of soluble proteins, such as amyloid β in Alzheimer's disease.
Journal ArticleDOI
Glial-conditional deletion of aquaporin-4 (Aqp4) reduces blood–brain water uptake and confers barrier function on perivascular astrocyte endfeet
Nadia Nabil Haj-Yasein,Gry Fluge Vindedal,Martine Eilert-Olsen,Georg Andreas Gundersen,Øivind Skare,Petter Laake,Arne Klungland,Anna E. Thoren,John M. Burkhardt,Ole Petter Ottersen,Erlend A. Nagelhus +10 more
TL;DR: The data suggest that the blood–brain barrier (BBB) is more complex than anticipated, and under certain conditions, the astrocyte covering of brain microvessels is rate limiting to water movement.
Journal ArticleDOI
Evidence that compromised K+ spatial buffering contributes to the epileptogenic effect of mutations in the human kir4.1 gene (KCNJ10)
Nadia Nabil Haj-Yasein,Vidar Jensen,Gry Fluge Vindedal,Georg Andreas Gundersen,Arne Klungland,Ole Petter Ottersen,Øivind Hvalby,Erlend A. Nagelhus +7 more
TL;DR: Combined K+ and extracellular volume recordings indicate that compromised K+ spatial buffering in brain underlies the epilepsy phenotype associated with human KCNJ10 mutations.
Journal ArticleDOI
Evidence that pericytes regulate aquaporin-4 polarization in mouse cortical astrocytes
Georg Andreas Gundersen,Gry Fluge Vindedal,Øivind Skare,Erlend A. Nagelhus,Erlend A. Nagelhus,Erlend A. Nagelhus +5 more
TL;DR: The data support the concept that pericytes regulate AQP4 polarization, a member of the dystrophin-associated protein complex (DAPC), and the enrichment of α-syntrophin in membranes ensheathingpericytes persisted after Aqp4 gene deletion.
Journal ArticleDOI
Deletion of aquaporin-4 changes the perivascular glial protein scaffold without disrupting the brain endothelial barrier.
Martine Eilert-Olsen,Nadia Nabil Haj-Yasein,Gry Fluge Vindedal,Rune Enger,Georg Andreas Gundersen,Eystein Hellstrøm Hoddevik,Pétur Henry Petersen,Finn Mogens Haug,Øivind Skare,Øivind Skare,Marvin E. Adams,Stanley C. Froehner,John M. Burkhardt,Anna E. Thoren,Erlend A. Nagelhus +14 more
TL;DR: It is concluded that Aqp4 deletion reduces the expression of perivascular glial scaffolding proteins without affecting the endothelial barrier and that AQP4 and α‐syntrophin are mutually dependent upon each other for proper periv vascular expression.
