Early Endosomes Act as Local Exocytosis Hubs to Repair Endothelial Membrane Damage

March 20, 2023

[Advanced Science] Using live-cell imaging and correlative light and electron microscopy, it was demonstrated that membrane injury triggered a previously unknown exocytosis of early endosomes that was induced by Ca2+ entering through the wound.

CD45 Is Sufficient to Initiate Endothelial-to-Mesenchymal Transition in Human Endothelial Cells

March 20, 2023

[Arteriosclerosis Thrombosis And Vascular Biology] Scientists activated the endogenous CD45 promoter in human endothelial colony forming cells using CRISPR/inactive Cas9 transcriptional activation.

Endothelial DLL4 Is an Adipose Depot–Specific Fasting Sensor Regulating Fatty Acid Fluxes

March 20, 2023

[Arteriosclerosis Thrombosis And Vascular Biology] Researchers combined transcriptional analysis of native human adipose tissue microvascular endothelial cells (AT-EC) together with in vitro approaches in primary human AT-EC and in vivo and ex vivo studies of mice under fed and fasted conditions.

Serum Amyloid A and Interleukin -1β Facilitate LDL Transcytosis across Endothelial Cells and Atherosclerosis via NF-κB/Caveolin-1/Cavin-1 Pathway

March 20, 2023

[Atherosclerosis] Effects of serum amyloid A and IL-1β on transcytosis of low density lipoprotein (LDL) were measured by an in vitro LDL transcytosis model. NF-κB/caveolin-1/cavin-1 pathway activation was investigated by Western blots and ELISA.

Inflammatory Stimuli Induce Shedding of Heparan Sulfate from Arterial but Not Venous Porcine Endothelial Cells Leading to Differential Proinflammatory and Procoagulant Responses

March 20, 2023

[Scientific Reports] Using a 3D round-channel microfluidic system, the authors investigated the endothelial glycocalyx, particularly heparan sulfate, on porcine arterial and venous endothelial cells.

Exosome-Transmitted miR-29a Induces Colorectal Cancer Metastasis by Destroying the Vascular Endothelial Barrier

March 20, 2023

[Carcinogenesis] In vitro co-culture investigations further revealed that epithelial mesenchymal transition cancer cells released exosomal miR-29a, which altered vascular endothelial permeability.

Notch Pathways Regulate Expression of Angiostatic Factor Activin A in Endothelial – Pericyte-like Mesenchymal Stromal Cell Interactions

March 20, 2023

[Stem Cells And Development] Contributions of notch signaling pathways were evaluated in endothelial cell (EC)-adipose mesenchymal stem/stromal cell (ASC) co-cultures.

EPAS1 Resistance to miRNA-Based Regulation Contributes to Prolonged Expression of HIF-2 during Hypoxia in Human Endothelial Cells

March 20, 2023

[Gene] Scientists tested 23 microRNA that were predicted to interact with the EPAS1 transcript,18 of which were induced during prolonged hypoxia, and demonstrated that none of them were functional in vitro.

CD109-Regulated Mechanical Properties of Endothelial Cells

March 20, 2023

[Cytoskeleton] Researchers investigated the effect of the immobilization of CD109 antigen with specific antibodies on nanomechanical properties of human umbilical endothelial cells using atomic force microscopy in quantitative nanomechanical property mapping mode.

The Role of the Blood–Brain Barrier during Neurological Disease and Infection

March 20, 2023

[Biochemical Society Transactions] The authors evaluate and summarize some of the latest research on the role of the blood-brain barrier (BBB) during neurological disease and infection with a focus on the effects of inflammation and flow disturbances on the BBB.
