Sun Exposure, Vitamin D And Photohealth Over The Lifetime

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.
Nox Isoforms And Chemokine Receptors As Therapeutic Targets In Vascular Disease And Stroke

Summary
I am a pharmacologist (a scientist who studies drugs and how they work) trying to find new drugs to treat heart attacks and strokes. I seek to understand the pathways that cause white blood cells and free radicals to accumulate in the walls of arteries in patients with high blood pressure and high cholesterol, and in the brain after stroke. I will then test whether these pathways can be blocked with novel chemical compounds that may eventually be developed into drugs suitable for use in humans.
Professor Godfrey is an immunologist with a long standing history as a pioneer in the study of a specialised type of white blood cell, known as NKT cells. NKT cells are activated in response to lipid-based molecules that are thought to alert the immune system, via NKT cell activation, to the presence of infectious agents or other abnormalities. A better understanding of how NKT cells function will provide new approaches to battling a broad range of diseases where these cells are implicated, incl ....Professor Godfrey is an immunologist with a long standing history as a pioneer in the study of a specialised type of white blood cell, known as NKT cells.

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.
Understanding the immune response is proving extremely complex and promising results for disease treatments from animal models are often difficult to translate to new clinical therapies. My research is unearthing weaknesses in our current knowledge of the immune system and seeking to replace them with a foundation that can exploit new developments in computer modelling and systems biology. In this way I aim to rationally manipulate the immune response.
Understanding Immune Regulation During Parasitic Diseases.

Summary
Chronic infectious diseases such as HIV/AIDS, tuberculosis, malaria and leishmaniasis are responsible for significant morbidity and mortality. They are all characterised by severe immune dysfunction. We will study a parasitic infection to identify important immune cell populations and molecules that promote chronic infectious disease. This knowledge will enable the development of better treatments and vaccines for range of infectious diseases that affect people in many parts of the world.
This application will increase the impact of cancer immunotherapy on disease prevention and treatment, by developing new targets and novel combination immunotherapies. Outcomes will include an improved understanding of the immune reaction with cancer and more effective strategies to prevent cancer spread and safely target and eradicate a larger proportion of established and advanced malignant disease.
Defining The Requirements For Effective Immune Responses

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

The development of protective immunity is essential to fight infection. This depends on a small number of master regulatory transcription factors that drive the differentiation of precursor cells into mature immune cells such as NK, T and dendritic cells. This proposal will provide a fundamental advance in our understanding of immune cells and impact strategies aimed at the prevention and treatment of pathogen infections.
