Antigen-presenting cells control immune responses. Different types of these cells do different jobs and affect different diseases. We wish to control these processes by determining how the cells live and die. In particular we are interested in controlling the local immune responses during rejection of islet transplantation, which can cure type 1 diabetes.
Prevention Of Pancreatic Beta Cell Destruction In Diabetes

Summary
Associate Professor Helen Thomas is a molecular and cell biologist with a particular interest in pancreatic islet biology, studying the mechanisms of pancreatic beta-cell destruction in diabetes. The aim of this work is to develop strategies to protect these cells. Such protection will improve our ability to preserve beta-cell mass in type 1 and type 2 diabetes, and after islet transplantation.
My work focuses on cells of the immune system that act as sentinels on the lookout for invading pathogens and danger. These cells are called dendritic cells. I am particularly interested in understanding how these cells function within the bone marrow environment and how they may sense viral infection or cancerous cells within this tissue. We aim to understand their function in specific diseases including Lupus and in pre-leukemia conditions, and also in infectious and parasitic diseases.

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
Diabetes is a major health epidemic & diabetic complications are a major cause of morbidity and mortality in our community. My studies have increased our understanding of how inflammation contributes to diabetes but also directly led to the discovery of novel therapies that are been trialed in patients with type 1 diabetes undergoing islet cell transplants. My studies have increased our knowledge of the factors that lead to type 1 diabetes and the development of new treatments.
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.
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.

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.
The genetic material is packaged in the cell nucleus with histone proteins. Modifications of histones determine if a particular area of the genome is active or repressed. We are investigating the roles of a family of histone modifying proteins, the MYST proteins. Mutations in these proteins cause intellectual disability and cancer. The research program will provide knowledge that may become the basis for the development of drugs for the treatment of cancer and neurodegenerative disorders.
