    Prdm16 Supports Arterial Flow Recovery by Maintaining Endothelial Function

    Within the vasculature, Prdm16 expression was strictly expressed by arterial endothelial and smooth muscle cells.

    Programming to S1PR1+ Endothelial Cells Promote Restoration of Vascular Integrity

    Researchers addressed mechanisms of generation of a population of S1PR1+ endothelial cells and their pivotal role in restoring endothelial integrity.

    Abstract

    Transcription Factor FOXP2 Is a Flow-Induced Regulator of Collecting Lymphatic Vessels

    Through transcriptional analysis of murine dermal lymphatic endothelial cells, scientists identified Foxp2, a member of the FOXP family of transcription factors implicated in speech development, as a collecting vessel signature gene.

    Blood–Brain Barrier Opening by Intracarotid Artery Hyperosmolar Mannitol Induces Sterile Inflammatory and Innate Immune Responses

    Proteomic changes occurred within five min of intracarotid arterial hyperosmolar mannitol (ICAHM) infusion and returned to baseline by 96 hours. Transcriptomic analyses following ICAHM blood–brain barrier disruption further supported an sterile inflammatory response.

    Abstract

    Endothelial Cell Invasion Is Controlled by Dactylopodia

    Researchers showed that endothelial tip cells use dactylopodia as the main cellular protrusion for invasion into nonvascular extracellular matrix. They showed that dactylopodia and filopodia protrusions were balanced by myosin IIA and actin-related protein 2/3 activity.

    Endothelial IGF-1 Receptor Mediates Crosstalk with the Gut Wall to Regulate Microbiota in Obesity

    The authors used gene‐modified mice with endothelial cell‐specific overexpression of human IGF‐1R and their wild‐type littermates.

    Rapid Endotheliitis and Vascular Damage Characterize SARS-CoV-2 Infection in a Human Lung-Chip Model

    Using a vascularised lung‐on‐chip model, scientists found that infection of alveolar epithelial cells led to limited apical release of virions, consistent with reports of monoculture infection.

    Complement Activation by an Angiogenic Imbalance Leads to Systemic Vascular Endothelial Dysfunction: A New Proposal for the Pathophysiology of Preeclampsia

    Researchers evaluated whether angiogenic imbalance affected the expression and secretion of inhibitory complement factor H in endothelial cells, resulting in complement activation and systemic vascular endothelial dysfunction.
    [Journal of Reproductive Immunology]

    Abstract

    Vascular Dysfunction after Modelled TBI Is Rescued with Administration of Umbilical Cord Derived Mesenchymal Stromal Cells and Is Associated with Modulation of the Angiogenic Response

    Investigators hypothesized that the perivascular properties of human umbilical cord perivascular cells could reduce vascular dysfunction after modelled traumatic brain injury by preserving the pericyte-endothelial interactions.

    Abstract

    Total and Endothelial Cell-Derived Cell-Free DNA in Blood Plasma Does Not Change during Menstruation

    The authors measured total cell free (cf)DNA by targeting ALU repetitive sequences and measured endothelial-derived cfDNA by methylation-specific qPCR targeting an endothelium-unique unmethylated CDH5 DNA region.

    Sphingolipids in HDL – Potential Markers for Adaptation to Pregnancy?

    Scientists describe the relationship between plasma high density lipoprotein and vascular function during healthy pregnancy and details how this is lost in pre-eclampsia, a disorder of pregnancy associated with widespread endothelial dysfunction.
