    摘要: The invention relates to the adhesion of platelet GpIbα to strand β3 of domain A1 of von Willebrand factor (vWF), the strand β3 comprising amino acid residues at amino acid position 560-566 and/or a functional part or equivalent thereof, the platelet GpIbα, the GpIbα region comprising an amino acid sequence corresponding to a beta-switch loop of platelet GpIbα, comprising amino acid residues at amino acid position 227-242 and/or a functional part or equivalent thereof. The invention provides a method of interfering with adhesion of blood platelets to vWF that includes modulating adhesion. The invention further provides proteinaceous compounds, antibodies, medicaments and pharmaceutical compositions to that end. The invention also provides means and methods to increase platelet adhesion by topical application of a compound increasing platelet adhesion.
