    Dlg1 activates beta-catenin signaling to regulate retinal angiogenesis and the blood-retina and blood-brain barriers

    Chris Cho et al.
    Discs large homologue 1 (Dlg1) activates beta-catenin (i.e., canonical Wnt) signaling in CNS endothelial cells to regulate retinal angiogenesis and the development and maintenance of the blood-brain and blood-retina barriers.

    Neurovascular sequestration in paediatric P. falciparum malaria is visible clinically in the retina

    Valentina Barrera et al.
    Clinical, clinicopathological and image data from Malawian children shows that sequestration in P. falciparum cerebral malaria is visible clinically in the eye as orange retinal vessels and is strongly associated with death.

    Endocytic recycling and vesicular transport systems mediate transcytosis of Leptospira interrogans across cell monolayer

    Yang Li et al.
    L. interrogans utilizes endocytic recycling and vesicular transport systems for transcytosis across endothelial or epithelial barrier in blood vessels or renal tubules, which contributes to spreading and transmission of leptospirosis.

    Beta-catenin signaling regulates barrier-specific gene expression in circumventricular organ and ocular vasculatures

    Yanshu Wang et al.
    Elevating beta-catenin signaling converts endothelial cells in typically fenestrated central nervous system vasculature to a blood-brain barrier (BBB) phenotype and promotes a BBB gene expression program and chromatin landscape.

    eNOS-induced vascular barrier disruption in retinopathy by c-Src activation and tyrosine phosphorylation of VE-cadherin

    Takeshi Ninchoji et al.
    Vascular leakage from pathological vessels in retinopathy aggravates the disease, but endothelial junction stability and barrier integrity can be restored by blocking formation of nitric oxide.

    Absence of TGFβ signaling in retinal microglia induces retinal degeneration and exacerbates choroidal neovascularization

    Wenxin Ma et al.
    TGFβ signaling to retinal microglia is central to the regulation of neuroinflammatory responses relevant to age-related macular degeneration (AMD), a leading cause of blindness in the developed world.

    Hypoxia-induced metabolic stress in retinal pigment epithelial cells is sufficient to induce photoreceptor degeneration

    Toshihide Kurihara et al.
    Mouse models in which hypoxia can be genetically triggered in retinal pigmented epithelial cells show that hypoxia-induced metabolic stress alone can lead to photoreceptor atrophy/dysfunction.

    VEGF signaling regulates the fate of obstructed capillaries in mouse cortex

    Patrick Reeson et al.
    Mapping the fate of clogged brain capillaries reveals that VEGF signaling plays a critical role in dictating whether capillaries regain blood flow and persist or are pruned from the vascular tree.

    Brain micro-inflammation at specific vessels dysregulates organ-homeostasis via the activation of a new neural circuit

    Yasunobu Arima et al.
    A link between chronic stress and organ dysfunction is explained by the gateway reflex, in which brain micro-inflammation at specific vessels establishes a new neural pathway to induce fatal organ failure particularly in gastrointestine and heart.

    Silicone oil-induced ocular hypertension and glaucomatous neurodegeneration in mouse

    Jie Zhang et al.
    An effective and reversible mouse glaucoma model that replicates the secondary glaucoma in human patients caused by silicone oil after retina surgeries presents significant neurodegeneration, and is suitable for neuroprotectants selection.
