Platelets

The platelet research group investigates both haemostatic and non-haemostatic platelet biology using classical and nano-pharmacology. The group is especially interested in the following areas:

  • cancer-cell platelet interactions, mechanisms and pathophysiological implications
  • the development and application of pioneering approaches for studying platelet function for example, nano-balance, microfluidics, proteomics.
  • platelet-nanoparticle interactions; disposition and toxicity.
  • classical pharmacology of platelets and inhibitors of platelet function.
  • the role of the metalloproteinases in platelet function.
  • the design and evaluations of novel aspirin technologies that have lower toxicity and the capacity to release nitric oxide (mutual prodrugs).

The focus of the group is to understand better the physiological and pathological roles of platelets leading to the provision of new therapeutics or new ways of delivering established therapeutics with a better therapeutic profile.
