Expression of urokinase plasminogen activator receptor on monocytes and granulocytes is modulated by cardiac surgery
Abstrakt
Aims: Coronary artery bypass grafting (CABG) is linked to the induction of the blood coagulation/fibrinolysis cascade, which is an integral component of inflammation induced by cardiac surgery. We followed the modulation of urokinase plasminogen activator receptor uPAR (CD87) separately for monocytes and granulocytes in blood of cardiac surgery patients.
Methods: Expression of uPAR, analyzed as Median Fluorescence Intensity (MFI), on blood monocytes and granulocytes was determined by flow cytometry. Changes in uPAR expression in patients undergoing CABG using standard cardiopulmonary bypass ("on-pump") were compared to the changes in uPAR expression in patients undergoing CABG using mini-invasive cardiopulmonary bypass ("mini on-pump").
Conclusion: uPAR expression on granulocytes and monocytes is significantly modulated by cardiac surgery.
