WebAbstract Objective: GPVI (glycoprotein VI) is a key molecular player in collagen-induced platelet signaling and aggregation. Recent evidence indicates that it also plays important role in platelet aggregation and thrombus growth through interaction with fibrin (ogen). WebFibrinogen alone did not induce GPVI shedding ( Figure 5A), and shedding required fibrin polymerization as inclusion of GPRP ablated GPVI proteolysis ( Figure 5A-B), demonstrating that...
