(Submitter supplied) Following the identification of a critical time window of Blood Brain Barrier formation in the mouse embryo, we aimed to identify genes important for barriergenesis. To this end, we isolated cortical and lung E13.5 endothelial cells and compared expression between the two populations. The working hypothesis was that endothelial cells which are actively building a barrier would have a uniqe pattern of gene expression that would be detectable in comparison to a non-barrier endothelial population that is also active in vasculogenesis.

(Submitter supplied) The blood-brain barrier (BBB) consists of specific physical barriers, enzymes and transporters, which together maintain the necessary extracellular environment of the central nervous system (CNS). The main physical barrier is found in the CNS endothelial cell, and depends on continuous complexes of tight junctions combined with reduced vesicular transport. Other possible constituents of the BBB include extracellular matrix, astrocytes and pericytes, but the relative contribution of these different components to the BBB remains largely unknown. more...

(Submitter supplied) The Wnt signaling pathway regulates blood-brain barrier (BBB) formation and function in both development and pathogenesis of diseases, and is essential for CNS angiogenesis and BBB formation in both embryonic and postnatal development. However, how Wnt signaling affects brain tumor endothelial cells is largely unknown. We isolated endothelial cells from tumors in control or LGK974 treated mice, and analyzed the role of Wnt signaling inhibition on tumor endothelial cells.

(Submitter supplied) To explore the mechanisms through which GLUT1 controls EC function, we compared transcriptomic alterations induced by loss of GLUT1 by performing RNA sequencing analysis on freshly isolated ECs from P6 GLUT1EC-/- brains. At P6, 447 genes were differentially expressed between WT and GLUT1-/- ECs. Subsequent gene set enrichment analysis showed that within the most differentially expressed pathways, several ones were related to p53, as well as inflammatory related pathways.

(Submitter supplied) To explore the mechanisms through which GLUT1 controls EC function, we compared transcriptomic alterations induced by loss of GLUT1 by performing RNA sequencing analysis on freshly isolated ECs from adult (8 week old) GLUT1EC-/- brains. In adult brains ECs, 1494 genes were differentially expressed between WT and GLUT1-/- ECs but we did not observe compensatory upregulation of other GLUTs. Interestingly, pathway analysis revealed that ECs from GLUT1EC-/- mice were characterized by a robust activation of inflammatory and extracellular matrix pathways.

(Submitter supplied) Brain development requires a massive increase in brain lipogenesis and accretion of the essential omega-3 fatty acid docosahexaenoic acid (DHA). Brain acquisition of DHA is primarily mediated by the transporter Major Facilitator Superfamily Domain containing 2a (Mfsd2a) expressed in the endothelium of the blood-brain barrier. Mfsd2a transports DHA and other polyunsaturated fatty acids esterified to lysophosphatidylcholine (LPC-DHA). more...

(Submitter supplied) Canonical Wnt signaling in endothelial cells (ECs) is required for vascularization of the central nervous system (CNS) and for formation and maintenance of barrier properties unique to CNS vasculature. Gpr124 is an orphan member of the adhesion G-protein-coupled receptor family that is expressed in ECs and is essential for CNS angiogenesis and barrier formation via an unknown mechanism. Using canonical Wnt signaling assays in cell culture and genetic loss- and gain-of-function experiments in mice, we show that Gpr124 functions as a co-activator of Wnt7a- and Wnt7b-stimulated canonical Wnt signaling via a Frizzled receptor and Lrp co-receptor, and that Gpr124-stimulated signaling functions in concert with Norrin/Frizzled4 signaling to control CNS vascular development. more...

(Submitter supplied) Endothelial cells (ECs) in the central nervous system (CNS) acquire specialized barrier properties in response to extrinsic signals, with Wnt/β-catenin signaling coordinating multiple aspects of endothelial barrier function. We used human pluripotent stem cell (hPSC)-derived endothelial progenitor cells to profile the EC response to Wnt activation using multiple strategies, including the small molecule GSK-3 inhibitor CHIR 99021, and the CNS-derived ligands Wnt7a and Wnt7b.

(Submitter supplied) Using mice with targeted gene mutations, we identify (1) distinct roles for different canonical Wnt signaling components in central nervous system (CNS) vascular development and in the specification of the blood-brain and blood-retina barriers (BBB and BRB) and (2) differential sensitivities of the vasculature in various CNS regions to perturbations in canonical Wnt signaling components. We find nearly equivalent roles for Lrp5 and Lrp6 in brain vascular development and barrier maintenance but a dominant role for Lrp5 in the retinal vasculature, an especially high sensitivity of the BBB in the cerebellum and pons/interpeduncular nuclei to decrements in canonical Wnt signaling, and plasticity in the barrier properties of mature CNS vasculature. more...

(Submitter supplied) Signaling events that regulate central nervous system (CNS) angiogenesis and blood-brain barrier (BBB) formation are only beginning to be elucidated. By evaluating the gene expression profile of mouse vasculature, we identified DR6/TNFRSF21 and TROY/TNFRSF19 as regulators of CNS-specific angiogenesis in both zebrafish and mice. Furthermore, these two death receptors interact both genetically and physically and are required for vascular endothelial growth factor (VEGF)-mediated JNK activation and subsequent human brain endothelial sprouting in vitro. more...

(Submitter supplied) The formation, maintenance, and repair of the blood-brain barrier (BBB) are critical for central nervous system homeostasis. The interaction of endothelial cells with brain pericytes is known to induce BBB characteristics in brain endothelial cells during embryogenesis and could be used to differentiate human endothelial cells from stem cell source in in vitro BBB models. However, the molecular events involved in BBB maturation are not fully understood. more...

(Submitter supplied) Genetic variation in the population has an influence on the manifestation of monogenic as well as multifactorial disorders, with the underlying genetic contribution dependent on several interacting variants. Common laboratory mouse strains used for modelling human disease lack the genetic variability of the human population. Therefore, outcomes of rodent studies show limited correlation with human disease. more...

(Submitter supplied) We evaluated the effects of vascular endothelial growth factor -B (VEGF-B) and the deletion of its receptor VEGFR1 from endothelial cells on cardiac hypertrophy. Whole-genome transcriptomic analysis showed that overexpression of the ligand had similar effects on the heart transcriptome as deletion of its receptor. Both treatments also induced angiogenesis and mild cardiac hypertrophy. The aim of the study was to identify pathways, which mediate angiogenesis-induced cardiac hypertrophy.

(Submitter supplied) Reconstitution of a neurovascular unit model with blood-brain barrier (BBB) function is of great importance for drug development targeting cerebral diseases and study of brain disease mechanisms. In this study, we describe a human neurovascular unit chip designed by reconstituting necessary cellular and extracellular components in microfluidic devices. Dynamic three-dimensional co-culture of human cells (neural stem cells, brain microvascular endothelial cells, and brain vascular pericytes) in microfluidics with a stepwise unidirectional flow successfully established the chip with BBB-mimetic structural and functional features to be an effective barrier for drugs and cytokines. more...

(Submitter supplied) Bacterial meningitis is a deadly disease most commonly caused by Streptococcus pneumoniae that leads to severe neurological sequelae including cerebral edema, seizures, stroke, and mortality when untreated. Meningitis is initiated by the transfer of S. pneumoniae from hematogenous source into the brain across the blood-brain barrier (BBB); the mechanisms however are still poorly understood. Current treatment strategies include adjuvant dexamethasone therapy for cerebral edema, the prime reason for neurological complications and mortality, which is followed up by antibiotics. more...
