Haplo-Insufficiency of Profilin1 in Vascular Endothelial Cells Is Beneficial but Not Sufficient to Confer Protection against Experimentally Induced Atherosclerosis
[Cytoskeleton] The authors investigated the impact of endothelial cell-specific partial loss of profilin1 expression in atherosclerosis development.
SARS-CoV-2 Infection Activates Inflammatory Macrophages in Vascular Immune Organoids
[Scientific Reports] The authors established vascular immune organoids from human pluripotent stem cells and examined the effect of SARS-CoV-2 infection.
Glutamatergic Neuronal Activity Regulates Angiogenesis and Blood-Retinal Barrier Maturation via Norrin/β-Catenin Signaling
[Neuron] Using in vivo genetic studies in mice, scRNA-seq, and functional validation, researchers showed that deep plexus angiogenesis and paracellular blood-retinal barrier maturation were delayed in Vglut1−/− retinas where neurons failed to release glutamate.
Endomucin Selectively Regulates Vascular Endothelial Growth Factor Receptor-2 Endocytosis through Its Interaction with AP2
[Cell Communication and Signaling] The authors investigated the molecular mechanism underlying endomucin’s involvement in the regulation of vascular endothelial growth factor-induced endocytosis.
Anti-Lymphangiogenesis for Boosting Drug Accumulation in Tumors
[Signal Transduction and Targeted Therapy] Investigators verified that anlotinib, a tyrosine kinase inhibitor with anti-lymphangiogenesis activity, and SAR131675, a selective VEGFR-3 inhibitor, effectively decreased the density of tumor lymphatic vessels in mouse cancer models.
Canonical and Non-Canonical Roles of Complement in Atherosclerosis
[Nature Reviews Cardiology] Scientists summarize the classical and the emerging non-classical roles of the complement system in the pathogenesis of atherosclerosis.
NYU Langone Health’s New Optimal Aging Institute to Further Explore the Link Between Vascular Health & Aging
[NYU Langone Health] Researchers at the newly formed Optimal Aging Institute at NYU Langone Health have been awarded $31 million by the National Institutes of Health to study how vascular risk factors contribute to dementia and other age-related disorders in those over the age of 85, building upon existing research.
Endothelial DR6 in Blood-Brain Barrier Malfunction in Alzheimer’s Disease
[Cell Death & Disease] Investigators found that brain endothelial death receptor 6 (DR6) levels were significantly reduced in a murine model of Alzheimer's disease at the onset of amyloid-β accumulation.
The Requirement of the Mitochondrial Protein NDUFS8 for Angiogenesis
[Cell Death & Disease] The authors investigated the potential involvement of NADH:ubiquinone oxidoreductase core subunit S8 (NDUFS8) in angiogenesis. In HUVECs and other endothelial cell types, they employed viral shRNA to silence NDUFS8 or employed the CRISPR/Cas9 method to knock it out.
CD32 Captures Committed Haemogenic Endothelial Cells during Human Embryonic Development
[Nature Cell Biology] Researchers performed transcriptomic analysis of 28- to 32-day human embryos and observed that the expression of Fc receptor CD32 was highly enriched in the endothelial cell population that contained hemogenic endothelial cells.
A Brain-Specific Angiogenic Mechanism Enabled by Tip Cell Specialization
[Nature] Investigators revealed a molecular mechanism for brain-specific angiogenesis that operated under the control of Wnt7a/b ligands—well-known blood–brain barrier maturation signals.
Eph-Ephrin Signaling Couples Endothelial Cell Sorting and Arterial Specification
[Nature Communications] Researchers combined cell type-specific and inducible mouse genetics, flow experiments in vitro, single-cell RNA sequencing and biochemistry to show that the balance between ephrin-B2 and its receptor EphB4 was critical for arterial specification, cell sorting, and arteriovenous patterning.
