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.
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.
Oxidative Processes In Vascular Health And Disease

Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Pathophysiology And Treatment Of Malaria In Our Region

Summary
Malaria continues to kill 420,000 people/year. I will lead a team of clinical scientists in identifying how each of the different malaria parasites cause damage to small blood vessels, kidneys and other organs, and will test whether two different drugs can improve these processes and reduce illness. Many of my previous research findings have changed malaria treatment in Australia and across SE Asia, and, where appropriate, I will use new research findings to improve treatments.
Heart failure (HF) describes where the heart cannot pump adequately to meet the bodyÍs needs. Mortality remains high; therefore, there is an urgent need for new treatment approaches. The present grant aims to: (1) evaluate treatments for patients at high-risk for future development of HF (2) examine the ability to safely withdraw unnecessary HF drugs (3) focus on the effect of HF on the kidney via novel treatment strategies (4) examine the emerging role of cancer drugs in development of HF.
Improving Outcomes In Heart Failure Through Basic, Clinical And Translational Research

Summary
Heart failure (HF) is a common, chronic cardiovascular condition characterised by a reduced capacity of the heart to function. Patients with HF have a poor quality of life and significantly reduced survival. My proposed programme of research will improve the understanding of heart failure (HF) and lead to better treatments.
Personalised Exercise As Medicine. Optimising The Prescription To Maximise The Benefit

Summary
Humans have never been less physically active than in contemporary Western society. These studies will provide an evidence-basis to address the inactivity epidemic by laying the foundation for personalised and effective exercise prescriptions, to which people are more likely to adhere.
Sun Exposure, Vitamin D And Photohealth Over The Lifetime
Funder

Funding Amount
$622,655.00
Summary
Australia is a sunny country with a diverse population. Inappropriate sun exposure for skin type leads to skin cancer (mainly in the fair-skinned) and vitamin D deficiency (particularly in the darker-skinned). Potential benefits of sun exposure are broader than vitamin D production, but remain ill-defined. There are few data on appropriate sun exposure for children. This research fellowship builds the evidence to guide sun exposure messages.
Pancreatic Islet Inflammation And Its Role In Diabetes And Islet Transplantation

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.
