摘要

BACKGROUND The endothelial glycocalyx (GCX) plays an important role in vascular barrier function. Damage to the GCX occurs due to a variety of causes including hypoxia, ischemia-reperfusion, stress-related sympathoadrenal activation, and inflammation. Tranexamic acid (TXA) may prevent GCX degradation. The therapeutic window for TXA administration and the mechanism of action has been under review. Membrane-anchored proteases (sheddases) are key components in endothelial cell biology including the regulation of vascular permeability. The effect of TXA administration on stress-related GCX damage, and the role of sheddases in this process was studied in a cell-based model.
