Given its lack of a transmembrane domain, GPI-anchored uPAR has high mobility on the cell surface and can interact with later partners with the ability to communicate with the internal cell compartment to produce downstream intracellular signaling mediated by effector molecules, such as the focal adhesion kinase, Src, and Akt. uPAR binds vitronectin, and multiple cell receptors, such as different types of transmembrane receptor [the formyl peptide receptors (FPRs), integrins, and VEGFR2 [23] ], establishing crosstalk between membrane-bound uPAR and its co-receptors. Serum plasminogen activator urokinase receptor predicts elevated risk of acute respiratory distress syndrome in patients with sepsis and is positively associated with disease severity, inflammation and mortality ./cache/cord-305389-n5cppi72.txt ./txt/cord-305389-n5cppi72.txt
