Armed Oncolytic Myxoma Virus Induces Systemic Antitumor Immunity Against Solid Tumors in Immunocompetent Mice

Arming oncolytic myxoma virus with immunostimulatory transgenes, particularly the IL-15Rα-IL-15 fusion protein, significantly enhances both local and systemic antitumor immunity in immunocompetent mice by remodeling the tumor microenvironment to recruit effector immune cells and improve survival.

Polarized release of brain microvascular endothelial cell- derived extracellular vesicles is functionally coupled to leukocyte transendothelial migration

Brain microvascular endothelial cells release claudin-5-containing extracellular vesicles in a polarized manner from their apical surface, where they specifically bind to adherent leukocytes to facilitate transendothelial migration via a zipper-like mechanism.
