We have studied receptor-mediated bioadhesion in the context of blood coagulation and inflammation reactions under conditions of hemodynamic flow. This work has focused on:

  • Platelet and neutrophil homotypic and heterotypic aggregation.
  • Platelet GPIb adhesion to vWF.
  • PSGL-1/P-selectin adhesion: Neutrophil membrane tethering.
  • Thresholds in neutrophil string formation.
  • Red blood cell adhesion to platelets, neutrophils and fibrin.
  • Pathological flow on vWF structure
