    Visceral Obesity and Insulin Resistance Associate with CD36 Deletion in Lymphatic Endothelial Cells

    Investigators showed that that intestinal lymphatic endothelial cells (LECs) have an increasing CD36 expression from lymphatic capillaries to collecting vessels, and that LEC CD36 regulated lymphatic integrity and optimized lipid transport.

    DLL1 Orchestrates CD8+ T Cells to Induce Long-Term Vascular Normalization and Tumor Regression

    Scientists showed that elevated levels of Delta-like 1 (DLL1) in the breast and lung tumor microenvironment induced long-term tumor vascular normalization to alleviate tumor hypoxia and promoted the accumulation of interferon γ–expressing CD8+ T cells and the polarization of M1-like macrophages.

    Abstract

    Cancer-Secreted Exosomal miR-21-5p Induces Angiogenesis and Vascular Permeability by Targeting KRIT1

    Researchers showed the delivery of miR-21-5p from colorectal cancer (CRC) cells to endothelial cells via exosomes increased the amount of miR-21-5p in recipient cells, suggesting that exosomal miR-21-5p was involved in angiogenesis and vascular permeability in CRC.

    3D Cell Culture Using a Clinostat Reproduces Microgravity-Induced Skin Changes

    Investigators showed that under time-averaged simulated microgravity, the thickness of the endothelial cell arrangement increased by up to 59.75%, indicating skin irritation due to vasodilation, and that the diameter of keratinocytes and fibroblast co-cultured spheroids decreased by 6.66%, representing skin thinning.
