Summary
Blood platelets play a key role in blood clot formation, prevention of bleeding and are the principal elements contributing to thrombosis leading to heart attack and stroke. Numerous studies have defined pathways promoting platelet activity, however less is known about their negative regulation. In this fellowship I will examine the role for proteins, Dok2 and Dok1, in the negative regulation of platelets, hoping this leads to development of novel therapeutics for prevention of cardiac disease.

Summary
Biosensors use biomolecules to detect a chemical event. They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected.

They are becoming important for the rapid and reliable measurement of the concentrations of molecules in fluids. In human medicine they will be of great use to general practitioners and patients for instantaneous read outs of concentrations of many different biological molecules. How well a biosensor responds depends on the method in which the biomolecule is immobilised to a surface and the signal detected. We have made a significant advance in biosensing capabilities using a recombinant protein (thioredoxin) and demonstrated the improvement that is possible by (i) immobilising the protein in a highly oriented way and (ii) using a sensitive electrical signal to monitor the response. Here we will undertake more comprehensive testing by extending the number of proteins to include the 4 major classes of redox-sensitive biomolecules (proteins) in the body. This will enable us to establish the broad application of our methods and substantially improve our ability to commercialize our discoveries.Read moreRead less
