(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) Canonical Wnt signaling is crucial for vascularization of the central nervous system and blood-brain barrier (BBB) formation. BBB formation and modulation are not only important for development, but also relevant for vascular and neurodegenerative diseases. However, beyond the early requirement of Wnt signaling for brain capillary development, there is little understanding of how Wnt signaling further contributes to brain angiogenesis and BBB formation. more...

(Submitter supplied) The early blood vessels of the embryo and yolk sac in mammals develop by aggregation of de novo forming angioblasts into a primitive vascular plexus, which then undergoes a complex remodeling process. Angiogenesis is also important for disease progression in the adult. However, the precise molecular mechanism of vascular development remains unclear. It is therefore of great interest to determine which genes are specifically expressed in developing endothelial cells.Here, we utilized Flk1-deficient mouse embryos, which lack endothelial cells, to perform a genome-wide survey for genes related to vascular development.

(Submitter supplied) Context dependent molecular cues shape the formation of the cerebral vascular network and the function of the blood-brain barrier (BBB). The Wnt/ß-catenin pathway is orchestrating CNS vascular development, but downstream mediators have not been characterized. Here we generated an endothelial cell-specific R26-Axin1 overexpression (AOE) mouse model to inhibit Wnt/ß-catenin signaling. In AOE mice we discovered that blockade of Wnt/ß-catenin pathway leads to premature regression and remodeling without compromising BBB integrity. more...

(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 GPR124/RECK/WNT7 pathway essentially regulates central nervous system angiogenesis and blood-brain barrier (BBB) function. GPR124, a brain endothelial adhesion 7-pass transmembrane protein, associates with membrane RECK, which binds and stabilizes newly synthesized WNT7 for subsequent transfer to Frizzled (FZD) and canonical b-catenin signaling. GPR124 function remains enigmatic; while its extracellular domain (ECD) is required, the poorly conserved intracellular domain (ICD) appears to be variably required in mammals versus zebrafish, potentially mediated by bridging of the GPR124 and FZD ICDs by intracellular adaptor proteins. more...

(Submitter supplied) The mammalian brain, spinal cord, and retina are supplied by capillaries that do not permit free diffusion of molecules between serum and parenchyma, a property that defines the blood-brain and blood-retina barriers. Exceptions to this pattern are found in the circumventricular organs (CVOs), a set of small midline brain structures that are supplied by high permeability capillaries. In the eye and brain, high permeability capillaries are also present in the choriocapillaris, which supplies the retinal pigment epithelium and photoreceptors, and the ciliary body and choroid plexus, the sources of aqueous humor and cerebrospinal fluid, respectively. more...

(Submitter supplied) Vascular endothelial cells (ECs) derived from the central nervous system (CNS) variably lose their unique barrier properties during in vitro culture, hindering the development of robust assays for BBB function, including drug permeability and extrusion assays. In previous work (Sabbagh et al., 2018) we characterized transcriptional and accessible chromatin landscapes of acutely isolated CNS ECs. In this report, we compare transcriptional and accessible chromatin landscapes of acutely isolated CNS ECs versus CNS ECs in short-term in vitro culture. more...

(Submitter supplied) Vascular endothelial cell (EC) function depends on appropriate organ-specific molecular and cellular specializations. To explore genomic mechanisms that control this specialization, we have analyzed and compared the transcriptome, accessible chromatin, and DNA methylome landscapes from mouse brain, liver, lung, and kidney ECs. Analysis of transcription factor (TF) motifs at candidate cis-regulatory elements together with TF gene expression reveals both shared and organ-specific EC TFs. more...
