Abstract
Objective—We studied the impact of native (natCRP) and modified CRP (mCRP) isoforms on platelet adhesion and thrombus growth under arterial flow.Methods and Results—Blood was perfused over type I collagen at a wall shear rate of 1500 s−1, and platelet deposition and thrombus growth were evaluated by confocal microscopy. natCRP and mCRP were either incubated with blood before perfusion experiments or immobilized in the collagen surface and exposed to flowing blood. mCRP significantly increased platelet adhesion and thrombus growth when directly incubated with blood and when immobilized on a collagen surface (PPPConclusions—Our data indicate that whereas serum natCRP may not affect thrombus growth, mCRP displays a prothrombotic phenotype enhancing not only platelet deposition, but also thrombus growth under arterial flow conditions.Keywords
