Platelet Glycoprotein IIb/IIIa Inhibitors
Glycoprotein IIb/IIIa (GPIIb-IIIa) complexes (integrin aIIbb3) mediate platelet aggregation by binding fibrinogen or von Willebrand factor (vWF), protein cofactors that form bridges between adjacent platelets. The cross-linked adhesive proteins assemble platelets into the aggregate. Agents that block the function of the GPIIb-IIIa complex of platelets constitute a powerful new generation of ant...
متن کاملPlatelet glycoprotein IIb/IIIa inhibitors.
To the Editor: Platelet glycoprotein (GP) IIb/IIIa antagonists only prompt an overall 8.5% relative reduction in 30-day deaths or myocardial infarction in acute coronary syndromes (ACS),1 and Quinn et al1 suggested that this limited benefit may be due to factors such as antagonist-induced platelet activation. I suggest that limited benefits of GP IIb/IIIa inhibition are due basically to limited...
متن کاملThe genomic organization of platelet glycoprotein IIIa.
The platelet membrane glycoprotein (GP) IIb/IIIa complex, a member of the integrin family of adhesive receptors involved in cell-cell and cell-matrix interactions, contains binding sites for fibrinogen, von Willebrand factor, fibronectin, and vitronectin. Absence or defects of this receptor result in the platelet bleeding disorder Glanzmann's thrombasthenia. In this report, we describe the isol...

متن کاملCharacterization of autoantigenic epitopes on platelet glycoprotein IIb/IIIa using random peptide libraries.
Most patients with chronic immune thrombocytopenic purpura (ITP) have autoantibodies directed against the glycoprotein (GP) IIb/IIIa complex. We have used a filamentous phage library that displays random linear hexapeptides to identify peptide sequences recognized by these autoantibodies. Plasma antibody eluates from two patients were used to select for phage displaying autoantibody-reactive pe...
