Platelets are key blood elements that are essential for the prevention of bleeding in response to injury or infection. Overactive or spontaneously active platelets cause thrombosis and blood clot formation. My laboratory has identified new physiological pathways of activation of platelet metalloproteinases, the enzymes that regulate surface levels of the prothrombotic platelet receptors. By understanding this mechanism of receptor regulation, we can uniquely target platelet receptors in people w ....Platelets are key blood elements that are essential for the prevention of bleeding in response to injury or infection.

Associate Professor Kate Denton is an internationally recognised cardiovascular researcher. A focus of Dr Denton’s research is to find out why women do not respond to current treatments as well as men, and how factors in pregnancy (nutrition, stress, alcohol) drive the development of cardiovascular disease in offspring. Dr Denton is also leading research to understand why a new high blood pressure treatment (blocking nerves to the kidney) is proving more effective than expected.
Biomarkers For The Diagnosis And Prognostic Analysis Of Male Infertility

Summary
Male infertility is a common condition, affecting 1 in 15 men. Although a standard semen analysis is often performed to test whether a man is infertile, it is far from definitive. We have developed a new approach, by looking at proteins that are commonly missing from infertile sperm cells. From this analysis, we can definitively diagnose male infertility and are beginning to understand why men are becoming infertile.

Summary
This fellowship will capitalise on my extensive expertise in determining the three-dimensional atomic structures of proteins to uncover fundamental biological mechanisms in cancer and Alzheimer’s disease as a basis for discovering new drugs to combat these devastating diseases.
Many bacterial pathogens invade host cells to replicate and avoid detection by the host. These pathogens interact with the host and by manipulating it to its benefit they establish an environment to survive in. A detailed understanding of the targeted hosts pathways and which are essential for pathogen survival is knowledge that will allow future development of therapeutic intervention strategies.
The regulation to early T cell signalling is a critical step in immune responses. Superimposed onto the biochemical pathways is a spatial organization that defines the immunological synapse. My research aims to map the principles of the spatial organization on the molecular scale to identify how lipids could unbalance the dynamic signalling equilibrium, for example in obese patients. To achieve this goal, my research group has developed single molecule microscopy approaches.
I study hormone action at the molecular level, particularly that of growth hormone action. I focus on the mechanism of activation of its receptor, notably as a target for cancer therapy, since growth hormone is necessary for the progression of many types of cancer. The ability of growth hormone to activate neural stem cells for a prolonged period in response to voluntary exercise is also a key interest. So too is the 40% extension of lifespan in mice after genetically deleting the growth hormone ....I study hormone action at the molecular level, particularly that of growth hormone action.

I am a reproductive biologist focused on women’s reproductive health. I am studying the reasons why some women are infertile have spontaneous abortions and pregnancy complications such as pre-eclampsia. My research will define the roles of molecules that are critical in the establishment of pregnancy and the formation of a health placenta and therefore a healthy baby.
An inability to control human fertility is an issue of global significance. Frequently both unwanted pregnancies and infertility result from the same origin, a lack of understanding of how germ cells are produced. Within this fellowship I will define key processes involved in the manifestation of male fertility. Further I will extend these insights into both the fertility clinic but also into human health more broadly.
